    We present a study of the scaling relations (SRs) between the masses of Supermassive Black Hole (SMBH) and the structural parameters of the host galaxies in the local Universe. This work is based mainly on two-dimensional (2D) photometric decompositions of near-infrared (NIR) images of 2MASS, as well as on an ongoing mid-infrared data analysis for a sample of galaxies with direct MBH estimates comprising late- to early-type galaxies. We first verify the accuracy of our photometric decomposition by examining the Fundamental Plane (FP) and its projections, such as Kormendy and Faber-Jackson, Luminosity-Size, among other SRs, and the for SMBH relations with host galaxy parameters. We place our results also in the context of bulge types, namely, classical and pseudo bulges. In general, we found that classical bulges follow the same relations as elliptical galaxies, while pseudobulges are usually outliers; however, pseudobulges show a trend that is weakly consistent with BH scaling relations. We also provide a complementary bulge classification criterion. Next, we move on to explore the high-mass regime of SRs by including core elliptical galaxies, and we find that core galaxies tend to present flatter slopes in SRs. We highlight that the trends found across the different populations in SRs, such as classical bulges, pseudobulges, lenticular, elliptical, and core galaxies, arise from distinct evolutionary pathways.

    #1: Una galaxia moribunda desencadena el nacimiento de nuevas estrellas
    30/01/2022

    ¿Qué provocó el nacimiento de nuestro Sol? Un artículo reciente de investigadores del Instituto de Radioastronomía y Astrofísica (IRyA) sugiere que la respuesta puede estar en una pequeña galaxia satélite que está siendo devorada lentamente por nuestra galaxia, la Vía Láctea.
