The gamma‐ray emission from young radio galaxies and quasars
Astronomische Nachrichten, Volume 342, Issue 9-10, Page 1176-1179, November-December 2021., 2021 Abstract According to radiative models, radio galaxies are predicted to produce γ‐rays from the earliest stages of their evolution onwards. The study of the high‐energy emission from young radio sources is crucial for providing information on the most energetic processes associated with these sources, the actual region responsible for this emission, as

Overmassive Black Holes in Dwarf Galaxies Out to z ∼ 0.9 in the VIPERS Survey
The Astrophysical Journal Letters, 2023 Supermassive black holes (SMBHs) are thought to originate from early universe seed black holes of mass M _BH ∼ 10 ^2 –10 ^5 M _⊙ and grown through cosmic time. Such seeds could be powering the active galactic nuclei (AGN) found in today’s dwarf galaxies.

The host galaxy/AGN connection [PDF]
Astronomy & Astrophysics, 2007 [ABRIDGED] We recently presented evidence of a connection between the brightness profiles of nearby early-type galaxies and the properties of the AGN they host. The radio loudness of the AGN appears to be univocally related to the host's brightness profile: radio-loud nuclei are only hosted by ``core'' galaxies while radio-quiet AGN are only found in ``

GRB Host Galaxies: An Unbiased Sample [PDF]
, 2011 We describe the current status and recent results from our Swift/VLT legacy survey, a VLT Large Programme aimed at characterizing the host galaxies of a homogeneously selected sub-sample of Swift GRBs.

Star-forming AGN host galaxies [PDF]
New Astronomy Reviews, 2001 The symbiosis of nuclear activity and star-formation in galaxies, as manifested in their spectral energy distributions (SEDs) is reviewed. Attention is drawn to an Hertzsprung-Russell diagram-equivalent for such objects, as well as to the importance of the SEDs in cosmological context.

The bulge-disc decomposition of AGN host galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We present the results from a study of the morphologies of moderate luminosity X-ray selected AGN host galaxies in comparison to a carefully mass-matched control sample at 0.5 < z < 3 in the CANDELS GOODS-S field. We apply a multi-wavelength morphological decomposition analysis to these two samples and report on the differences between the ...

Comparing metallicity correlations in nearby non-AGN and AGN-host galaxies [PDF]
The gas-phase metallicity distribution within galaxies records critical information about galactic evolution. In this work, we investigate how active galactic nuclei (AGNs) influence this distribution by measuring the two-point correlation functions of ...

The Astrophysical Journal, 2023 Pairs of galaxies hosting active galactic nuclei (AGNs) are powerful probes of merger-driven supermassive black hole (SMBH) growth as they can resolve individual AGNs and trace mergers over a large range of physical separations.

Radio galaxies in zFourGE/NMBS : no difference in the properties of massive galaxies with and without radio-AGN out to z=2.25 [PDF]
, 2016 In order to reproduce the high-mass end of the galaxy mass distribution, some process must be responsible for the suppression of star formation in the most massive of galaxies.
