Radio Active Galactic Nuclei Activity in Low Redshift Galaxies Is Not Directly Related to Star Formation Rates

The Astrophysical Journal
We examine the demographics of radio-emitting active galactic nuclei (AGN) in the local Universe as a function of host galaxy properties, most notably both stellar mass ( M _⋆ ) and star formation rate (SFR).

The Host Galaxy Fluxes of Active Galaxy Nuclei Are Generally Overestimated by the Flux Variation Gradient Method

Universe
In terms of the variable nature of normal active galaxy nuclei (AGN) and luminous quasars, a so-called flux variation gradient (FVG) method has been widely utilized to estimate the underlying non-variable host galaxy fluxes.

First Light and Reionization Epoch Simulations (FLARES) -- XV: The physical properties of super-massive black holes and their impact on galaxies in the early universe

The Open Journal of Astrophysics
Understanding the co-evolution of super-massive black holes (SMBHs) and their host galaxies remains a key challenge of extragalactic astrophysics, particularly the earliest stages at high-redshift.

Narrow [O iii] Emission Lines as a Potential Proxy for the Evolutionary Stage of Quasars

The Astrophysical Journal
Radio spectral shape of quasars can provide insight into the ages of quasars. We have compiled data for 1804 quasars with z ≲ 1 from the Sloan Digital Sky Survey (SDSS).

Agn Host Galaxy Properties And Mass Function

, 2016
Supermassive black hole growth, nuclear activity, and galaxy evolution have been found to be closely related. In the context of AGN-galaxy coevolution, I will discuss about the relation found between the host galaxy properties and the central BH and I will present the latest determination of the host galaxy stellar mass function (HGMF), and the ...

Intrinsic and Environmental Effects on the Distribution of Star Formation in TNG100 Galaxies

The Astrophysical Journal
We present radial profiles of luminosity-weighted age (age _L ) and ΔΣ _SFR for various populations of high- and low-mass central and satellite galaxies in the TNG100 cosmological simulation.
