Science

- Fields of research. Research in both theoretical and observational astrophysics:

Cosmology and large-scale structure of the Universe.
Book about cosmology from a sceptical point of view, compiling scientific, philosophical and sociological arguments [158]. Review on the caveats and open questions in the standard cosmology[44,100,129,170]; book review on a text about this topic[101]. Review on tests on the expansion of the Universe[114], review on problems of dark matter and dark energy hypotheses [135], review on alternative cosmological models [161].
Cosmological tests, comparing observations at different redshifts with predictions of different cosmological models, either with expansion or static: measurement of the angular size variation in galaxies[86]; measurement of the ratio between angular sizes and sizes along the line of sight (Alcock-Paczynski test)[106,123,162]; use of Hubble diagram of QSOs using a nonlinear relation between the ultraviolet and X-ray luminosities[120]; Hubble diagram in supernovae[163]. Relationship in spiral galaxies of size, internal attenuation and dust emission and possible uses as cosmological test [155].
Study on the historical evolution of measurements of two cosmological parameters: the Hubble constant [148,165] and amplitude of mass fluctuations [148], showing that the recent "Hubble tension" is most likely due to an underestimation of error bar, as it was in the past.
Cosmic Microwave Background Radiation (CMBR) anisotropies: Galactic contamination[18,52,68], Sunyaev-Zel'dovich effect in the interaction with cluster of galaxies[128], analysis on the origin of the peaks in the power spectrum for any cosmology[103,104], lack of large-angle correlations in the fluctuations that argues against the basic inflationary paradigm, and perhaps even suggests non-inflationary alternatives for the origin and growth of perturbations in the early Universe[130,156].
Large-scale structure of the Universe, distribution of galaxies: application of statistical mechanics[1,12]; analytical calculation of the evolution of these structures in the non-linear regime[23,32]; statistical analysis of data[7,8,45,73,80]; measurement of the correlation between CMBR anisotropies and galaxy counts[85], something that should be detected if dark energy existed, with the result of an absence of such a correlation, against the claims of some cosmologists. Dust content of galaxy clusters[111,124].

Estimation of the ages of galaxies at high redshift, to constrain the possible scenarios of formation of extremely red and massive elliptical galaxies observed at redshifts between 0.8 and 3.8 [83,95,127], and showing that using "cosmic chronometers" is not a good method [127,133] for age evolution analysis.
Exploration of the variation of the fine structure constant along cosmological timescale[87,92,118], with the result of a compatibility with a constant value.
Anomalous redshifts in apparently linked systems of galaxies/QSOs with different redshifts [34,35,46,48,53,54,58,71,81]: some old anomalies are still present, but the data do not allow to conclude the existence of non-cosmological redshifts. Press release with the highlights of the workshop about alternative mechanisms to produce redshifts which was held in Clonakilty-Cork, Ireland in May 15-18, 2006 [57]. Theoretical scenarios and tests of massive photons [152,171].

Quasars/QSOs.
Review on problems in our understanding of QSOs[89].
Non-evolution of the dependence of black hole masses on bolometric luminosities for QSOs[97].
Analysis of the observed distribution of jets with superluminal motions, to conclude that the kinetic power of each quasar should be much higher than previously estimated, on the order of the bolometric luminosity[99].
Observation of optical counterparts of ULX (Ultraluminous X-ray Sources) near some galaxies, to conclude that many (most) of them are background QSOs[47,50,54,56,66,79].

Milky Way structure.
Development of some tools of analysis: calculation of correlations functions in the distribution of stars to derive information about the position of the clusters[11,17]; analytical solution for the correction of star counts subject to confusion in overcrowded fields [9,11]; the inversion of the stellar statistics equation applied to the Galactic Bulge[11,13,15,22,29,51,74]; the use of Red clump giant stars as tracers of Galactic structure[38,82].
Observational works dedicated to the morphological study of the components of the Galaxy: the bulge[11,13,15,20,22,25,26,27,28,29,51,61,63,65,74,76,77,122,125,139,160], the "long bar"[2,4,5,6,11,14,16,19,20,24,28,31,59,61,63,64,65,74,77,91,93,102,105]; the disc[20,27,38,39,49,60,69,72,75,109,115,131,146,147,159], spiral arms[126]; the extinction by dust[43]. There is a distinction of the bar and the bulge as different structures, possibly with different angles, something which was also observed in other galaxies[112]. Remarkably is the refutation [122,125,139,160] of an X-shaped bulge claimed by other authors.
Against other hypotheses which aimed to discover a new satellite dwarf galaxy to explain the excess of stars in the region of Canis Major, arguments were given [55,67] to think that there is not such a galaxy but it is a projection effect of the warp+flare in the external disc of the Milky Way. Moreover, the Monoceros ring, which was assumed to be a stream associated to the remnants of this dwarf galaxy in the interaction with the Milky Way, does also appear instead to be part of our Galaxy, being its excess star counts due to the flare of the thick disc [90,98,109].

Galactic kinematics and dynamics.
Invited review on dynamics and kinematics of the Milky Way disc [151]. Kinematics and dynamics in the Milky Way: From the proper and radial heliocentric motions of stars in the outer disc, its rotation speed is obtained [107,134,136,140,142,149,150,166], the motions perpendicular to the plane [113,116,134,136,140,142,143,144,147,166,167] and Galactocentric radial motions [121,134,136,137,140,142,143,144,166]. Also, analysis of radial motion in other galaxies[138]. A case against the discovery of the precession of the Galactic warp [154].
Rotation curves: theoretical research on the relationship between disc density and velocities [145]. Fit of Milky Way rotation curve with models of dark matter or modified gravity (MOND) [149,169]. Exact Semianalytical Calculation of Rotation Curves with Bekenstein-Milgrom Nonrelativistic MOND [153]. Solution of an old problem: virial theorem in clusters of galaxies with MOND [164,168].
Research about the hypothesis of an extragalactic origin of the High Velocity Clouds, as part of the intergalactic medium in the Local Group[21,42] and with large ratio of dark matter. Development of a new hypothesis that explains the generation of warps in spiral galaxies due to the accretion of intergalactic flows directly onto the disc [33,42,70]. Analysis of the correlations between intrinsic parameters and warp characteristics of spiral warped galaxies [36,42], concluding that very massive hypothetical dark matter haloes have nothing to do with the formation of warps; in agreement with the hypothesis. Also, a catalog of optical warps[41] shows that most of the spiral galaxies are warped while no lenticular galaxy is warped. This is again in agreement with my the hypothesis because lenticular galaxies have no gas and the accretion onto the disc can only be produced if there is gas in the disc. The flaring of the disc as a function of the galactocentric angle is another fact which is in agreement with the hypothesis [70,78].
Study of the effect of the bar of spiral galaxies to increase the accretion of intergalactic matter into the haloes [62]. Dynamical study of two isolated bars with allowed geometric deformation described as modified Jacobi ellipsoids [110]: the bars repel to each other and the exchange of angular momentum will cause them to modify its geometry by enlarging its long axis. Analysis of the correlation between the number of tidal dwarf satellite galaxies and the size of the bulge [119]: it was found out in a level of 5-sigma, which points out that the formation of bulges has to do with the interaction among galaxies, as predicted in models of modified gravity. Criticism on the discovery of a galaxy without dark matter [132].

Other researches. Observation of optical counterparts of Gamma Ray Bursts[37,40]. Search of stars that were in old surveys and are not observed at present[141]. Participation in the near infrared photometric survey VISTA [84,88,94,96,108], and the optical photometric and spectroscopic survey SDSS-III [117,157].

BACK TO THE INDEX

	Cosmology and large-scale structure of the Universe. Book about cosmology from a sceptical point of view, compiling scientific, philosophical and sociological arguments [158]. Review on the caveats and open questions in the standard cosmology[44,100,129,170]; book review on a text about this topic[101]. Review on tests on the expansion of the Universe[114], review on problems of dark matter and dark energy hypotheses [135], review on alternative cosmological models [161]. Cosmological tests, comparing observations at different redshifts with predictions of different cosmological models, either with expansion or static: measurement of the angular size variation in galaxies[86]; measurement of the ratio between angular sizes and sizes along the line of sight (Alcock-Paczynski test)[106,123,162]; use of Hubble diagram of QSOs using a nonlinear relation between the ultraviolet and X-ray luminosities[120]; Hubble diagram in supernovae[163]. Relationship in spiral galaxies of size, internal attenuation and dust emission and possible uses as cosmological test [155]. Study on the historical evolution of measurements of two cosmological parameters: the Hubble constant [148,165] and amplitude of mass fluctuations [148], showing that the recent "Hubble tension" is most likely due to an underestimation of error bar, as it was in the past. Cosmic Microwave Background Radiation (CMBR) anisotropies: Galactic contamination[18,52,68], Sunyaev-Zel'dovich effect in the interaction with cluster of galaxies[128], analysis on the origin of the peaks in the power spectrum for any cosmology[103,104], lack of large-angle correlations in the fluctuations that argues against the basic inflationary paradigm, and perhaps even suggests non-inflationary alternatives for the origin and growth of perturbations in the early Universe[130,156]. Large-scale structure of the Universe, distribution of galaxies: application of statistical mechanics[1,12]; analytical calculation of the evolution of these structures in the non-linear regime[23,32]; statistical analysis of data[7,8,45,73,80]; measurement of the correlation between CMBR anisotropies and galaxy counts[85], something that should be detected if dark energy existed, with the result of an absence of such a correlation, against the claims of some cosmologists. Dust content of galaxy clusters[111,124]. Estimation of the ages of galaxies at high redshift, to constrain the possible scenarios of formation of extremely red and massive elliptical galaxies observed at redshifts between 0.8 and 3.8 [83,95,127], and showing that using "cosmic chronometers" is not a good method [127,133] for age evolution analysis. Exploration of the variation of the fine structure constant along cosmological timescale[87,92,118], with the result of a compatibility with a constant value. Anomalous redshifts in apparently linked systems of galaxies/QSOs with different redshifts [34,35,46,48,53,54,58,71,81]: some old anomalies are still present, but the data do not allow to conclude the existence of non-cosmological redshifts. Press release with the highlights of the workshop about alternative mechanisms to produce redshifts which was held in Clonakilty-Cork, Ireland in May 15-18, 2006 [57]. Theoretical scenarios and tests of massive photons [152,171].
	Quasars/QSOs. Review on problems in our understanding of QSOs[89]. Non-evolution of the dependence of black hole masses on bolometric luminosities for QSOs[97]. Analysis of the observed distribution of jets with superluminal motions, to conclude that the kinetic power of each quasar should be much higher than previously estimated, on the order of the bolometric luminosity[99]. Observation of optical counterparts of ULX (Ultraluminous X-ray Sources) near some galaxies, to conclude that many (most) of them are background QSOs[47,50,54,56,66,79].
	Milky Way structure. Development of some tools of analysis: calculation of correlations functions in the distribution of stars to derive information about the position of the clusters[11,17]; analytical solution for the correction of star counts subject to confusion in overcrowded fields [9,11]; the inversion of the stellar statistics equation applied to the Galactic Bulge[11,13,15,22,29,51,74]; the use of Red clump giant stars as tracers of Galactic structure[38,82]. Observational works dedicated to the morphological study of the components of the Galaxy: the bulge[11,13,15,20,22,25,26,27,28,29,51,61,63,65,74,76,77,122,125,139,160], the "long bar"[2,4,5,6,11,14,16,19,20,24,28,31,59,61,63,64,65,74,77,91,93,102,105]; the disc[20,27,38,39,49,60,69,72,75,109,115,131,146,147,159], spiral arms[126]; the extinction by dust[43]. There is a distinction of the bar and the bulge as different structures, possibly with different angles, something which was also observed in other galaxies[112]. Remarkably is the refutation [122,125,139,160] of an X-shaped bulge claimed by other authors. Against other hypotheses which aimed to discover a new satellite dwarf galaxy to explain the excess of stars in the region of Canis Major, arguments were given [55,67] to think that there is not such a galaxy but it is a projection effect of the warp+flare in the external disc of the Milky Way. Moreover, the Monoceros ring, which was assumed to be a stream associated to the remnants of this dwarf galaxy in the interaction with the Milky Way, does also appear instead to be part of our Galaxy, being its excess star counts due to the flare of the thick disc [90,98,109].
	Galactic kinematics and dynamics. Invited review on dynamics and kinematics of the Milky Way disc [151]. Kinematics and dynamics in the Milky Way: From the proper and radial heliocentric motions of stars in the outer disc, its rotation speed is obtained [107,134,136,140,142,149,150,166], the motions perpendicular to the plane [113,116,134,136,140,142,143,144,147,166,167] and Galactocentric radial motions [121,134,136,137,140,142,143,144,166]. Also, analysis of radial motion in other galaxies[138]. A case against the discovery of the precession of the Galactic warp [154]. Rotation curves: theoretical research on the relationship between disc density and velocities [145]. Fit of Milky Way rotation curve with models of dark matter or modified gravity (MOND) [149,169]. Exact Semianalytical Calculation of Rotation Curves with Bekenstein-Milgrom Nonrelativistic MOND [153]. Solution of an old problem: virial theorem in clusters of galaxies with MOND [164,168]. Research about the hypothesis of an extragalactic origin of the High Velocity Clouds, as part of the intergalactic medium in the Local Group[21,42] and with large ratio of dark matter. Development of a new hypothesis that explains the generation of warps in spiral galaxies due to the accretion of intergalactic flows directly onto the disc [33,42,70]. Analysis of the correlations between intrinsic parameters and warp characteristics of spiral warped galaxies [36,42], concluding that very massive hypothetical dark matter haloes have nothing to do with the formation of warps; in agreement with the hypothesis. Also, a catalog of optical warps[41] shows that most of the spiral galaxies are warped while no lenticular galaxy is warped. This is again in agreement with my the hypothesis because lenticular galaxies have no gas and the accretion onto the disc can only be produced if there is gas in the disc. The flaring of the disc as a function of the galactocentric angle is another fact which is in agreement with the hypothesis [70,78]. Study of the effect of the bar of spiral galaxies to increase the accretion of intergalactic matter into the haloes [62]. Dynamical study of two isolated bars with allowed geometric deformation described as modified Jacobi ellipsoids [110]: the bars repel to each other and the exchange of angular momentum will cause them to modify its geometry by enlarging its long axis. Analysis of the correlation between the number of tidal dwarf satellite galaxies and the size of the bulge [119]: it was found out in a level of 5-sigma, which points out that the formation of bulges has to do with the interaction among galaxies, as predicted in models of modified gravity. Criticism on the discovery of a galaxy without dark matter [132].
