Relationship of supermassive black holes with global properties of galaxies

Abstract

On the basis of Castillo, Y. S. Master Thesis, which include a comprehensive bibliographic review from Astronomy and Astrophysics professional papers, related to super massive black holes (hereinafter SMBHs) and several properties of their host galaxies, ten publications considered representative has been selected, as regards data and significant correlations between central black hole masses and the global properties of the host galaxies. Taking these ten publications data, have been selected 11 relevant properties that were grouped into three kinds of tables: elliptical galaxies, disk galaxies and peculiar galaxies (peculiar includes active, irregular galaxies and mergers of galaxies). The final sample is 144 galaxies. 1,453 Data were collected in total. Also developed nine plots of correlations between central super massive black hole masses from the sample versus the following nine properties of galaxies: central velocity dispersion, bulb Luminosity, SMBH influence radio, bulb effective radio, spheroid mass, mass-luminosity ratio, redshift, distance from the center of the Galaxy, and far infrared luminosity. With the help of correlation plots became a comparative analysis between these correlations and correlations from five recent theoretical models of formation and evolution of galaxies. The results seem to support the formation of galaxies from dark matter halos that would later form disk galaxies, whose central black holes would be galactic growth engines, at moderate accretion rates.

Keywords: super massive black hole (SMBH); correlation; galaxy; velocity dispersion; evolution; formation.
