Abstract:
The relation between the mass of the supermassive black hole (SMBH) in
the center of galaxies and their bulge mass or central velocity
dispersion is well known. This suggests a coevolution between the
SMBHs and their galaxy hosts. Our aim is to study this relation,
specifically, for radio loud galaxies, and as a function of redshift
z. We selected a sample of 42 radio galaxies and active galactic
nuclei (AGN) with broad emission lines and spectroscopic redshifts
between z=0.3-4 by cross-matching the low radio frequency sources from
Very Large Array (VLA) FIRST with spectroscopically confirmed galaxies
from wide-field surveys, including Sloan Digital Sky Survey (SDSS)
DR14 ugriz and Dark Energy Survey (DES) DR2 grzY in the optical, Wield
Infrared Survey Explorer (WISE), and the Galaxy And Mass Assembly
(GAMA) spectroscopic survey. We characterized the stellar mass (M*),
star formation, and black hole properties (mass of the central SMBH,
Eddington ratio η , and jet power, Qmjet. The relation between
SMBH mass, M*, η , and z is placed into context by comparing
them with scaling relations (MmBH-M*, MmBH/M*-z,
MmBH-Qmjet_, and Qmjet-η from the literature. On the basis of
a multiwavelength spectral energy distribution modeling, our radio
sources are broadly consistent with being on the star-forming main
sequence. They have sub-Eddington accretion rates, η~=1% on
average, as typically found in type I AGN, while higher accretion
rates favor more powerful jets to be launched by the central engine.
We find overmassive SMBHs in (17±5% of our radio sources, similarly
to previous studies on nearby early-type galaxies. Altogether, an
evolutionary scenario in which radio-mode AGN feedback regulates the
accretion onto the SMBHs and the stellar mass assembly of the radio
sources is discussed, which may explain the observed phenomenology.
This pilot study represents a benchmark for future studies using
wide-field surveys such as Euclid and the Vera Rubin telescope.
