  • The main result of this analysis is the finding of an important phase of bulge growing at z~1, where a meaningful fraction of galaxies show high nuclear surface densities and blue colors that correspond, probably, to strong episodes of star formation conf
    The ideas on the formation history of disk galaxy bulges can beconfronted with direct observations of high redshift bulge precursors. Of vital importance is the search for strong episodes of star formation in the nuclei of the galaxies. Those episodes can result from secular processes that drive material from the outer regions inward, related to the phenomenon of the pseudobulges in the local Universe. Alternatively, they can be a consequence of rejuvenation procesess of old and red classical bulges formed at high redshifts. It is possible to distinguish between both types of bulges using a

  • Caption: Qb in in the horizontal axis and dust lane curvature of the observed galaxies in the vertical axis.
    We tested the theoretical prediction that the straightest dust lanes in bars are found in strongly barred galaxies, or more specifically, that the degree of curvature of the dust lanes is inversely proportional to the strength of the bar. The test used archival images of barred galaxies for which Qb (which has been called the bar strength parameter) was known. Our results confirm the theoretical prediction but show a large spread that cannot be accounted for by the measurement errors. We simulated 238 galaxies with different bar and bulge parameters in order to investigate the origin of the

  • Hace unos meses apareció publicado un libro bajo el título “¿Dios o la materia?” (Ed. Altera, 2008). Podría parecer una obra más de las muchas que se han lanzado al mercado editorial como remedio homeopático para la existencia. Sin embargo, dos aspectos llaman la atención: el primero, que se plantee bajo signos de interrogación, lo que sugiere la sana costumbre de proponer preguntas en lugar de ofrecer verdades únicas; y el segundo, un tentador subtítulo aclarando lo que en él se ofrece:”un debate sobre cosmología, ciencia y religión”. Es decir, que nos encontramos en un cruce de caminos, un
