The bulge-disc decomposition of AGN host galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 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 99.7% confidence level, according to all model fits even those which adopt a ...

AGN Absorption Linked to Host Galaxies [PDF]
Proceedings of the International Astronomical Union, 2013 Multiwavelength identification of AGN is crucial not only to obtain a more complete census, but also to learn about the physical state of the nuclear activity (obscuration, efficiency, etc.).

GALAXIES ON DIET: FEEDBACK SIGNATURES IN RADIO-AGN HOST GALAXIES [PDF]
Publications of The Korean Astronomical Society, 2017 There exists strong evidence supporting the co-evolution of central supermassive black holes and their host galaxies; however it is still under debate how such a relation comes about and whether it is relevant for all or only a subset of galaxies. An important mechanism connecting AGN to their host galaxies is AGN feedback, potentially heating up or ...

The mass-metallicity and fundamental metallicity relations in non-AGN and AGN-host galaxies [PDF]
Monthly notices of the Royal Astronomical SocietyGalaxies’ stellar masses, gas-phase oxygen abundances (metallicity), and star formation rates (SFRs) obey a series of empirical correlations, most notably the mass-metallicity relation (MZR) and fundamental metallicity relation (FZR), which relates ...

Clustering, host galaxies, and evolution of AGN
, 2009 We explore the connection between different classes of active galactic nuclei (AGNs) and the evolution of their host galaxies, by deriving host galaxy properties, clustering, and Eddington ratios of AGNs selected in the radio, X-ray, and infrared (IR) wavebands from the wide-field (9 deg^2) Bootes survey.

The Interplay between Radio AGN Activity and Their Host Galaxies [PDF]
Galaxies, 2023 Radio activity in AGN (Active Galactic Nuclei) produce feedback on the host galaxy via the impact of the relativistic jets on the circumnuclear gas. Although radio jets can reach up to several times the optical radius of the host galaxy, in this review we focus on the observation of the feedback deposited locally in the central region of the host ...

AGN host galaxies at redshift z 0.7: peculiar or not? [PDF]
Astronomy & Astrophysics, 2012 Aims. We perform a quantitative morphological comparison between the hosts of active galactic nuclei (AGN) and quiescent galaxies at intermediate redshifts (z ≈ 0.7).

HERSCHEL OBSERVED STRIPE 82 QUASARS AND THEIR HOST GALAXIES: CONNECTIONS BETWEEN AGN ACTIVITY AND HOST GALAXY STAR FORMATION [PDF]
, 2016 In this work, we present a study of 207 quasars selected from the Sloan Digital Sky Survey quasar catalogs and the Herschel Stripe 82 survey. Quasars within this sample are high-luminosity quasars with a mean bolometric luminosity of 1046.4 erg s−1.
