Jet propagation through inhomogeneous media and shock ionization

Astronomische Nachrichten, Volume 342, Issue 9-10, Page 1171-1175, November-December 2021., 2021
Abstract In this contribution, we present the first numerical simulations of a relativistic outflow propagating through the inner hundreds of parsecs of its host galaxy, including atomic and ionized hydrogen, and the cooling effects of ionization. Our results are preliminary, but we observe efficient shock ionization of atomic hydrogen in interstellar ...

The central FR0 in the sloshing cluster Abell 795: Indications of mechanical feedback from Chandra data

Astronomische Nachrichten, Volume 342, Issue 9-10, Page 1207-1211, November-December 2021., 2021
Abstract We present a detailed study of the galaxy cluster Abell 795 and of its central Fanaroff‐Riley Type 0 (FR0) radio galaxy. From an archival Chandra observation, we found a dynamically disturbed environment with evidences for sloshing of the intracluster medium.

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 ...

Do Moderate-Luminosity Active Galactic Nuclei Suppress Star Formation? [PDF]

, 2009
The growth of supermassive black holes and their host galaxies are thought to be linked, but the precise nature of this symbiotic relationship is still poorly understood. Both observations and simulations of galaxy formation suggest that the energy input

The Kiloparsec-scale Influence of the AGN in NGC 1068 with SALT RSS Fabry–Pérot Spectroscopy

The Astronomical Journal, 2023
We present Fabry–Pérot (FP) imaging and longslit spectroscopy of the nearby Seyfert II galaxy NGC 1068 using the Robert Stobie Spectrograph (RSS) on the Southern African Large Telescope (SALT) to observe the impact of the central active galactic nucleus (

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 ...

The triggering probability of radio-loud AGN: A comparison of high and low excitation radio galaxies in hosts of different colors [PDF]

, 2012
Low luminosity radio-loud active galactic nuclei (AGN) are generally found in massive red elliptical galaxies, where they are thought to be powered through gas accretion from their surrounding hot halos in a radiatively inefficient manner.

The Incidence of Active Galactic Nuclei in Pure Disk Galaxies: The Spitzer View [PDF]

, 2009
We have conducted a high-resolution spectroscopic study using Spitzer of 18 bulgeless (Sd/Sdm) galaxies that show no definitive signatures of nuclear activity in their optical spectra. This is the first systematic mid-IR search for weak or hidden AGNs in

The first 62 AGN observed with SDSS-IV MaNGA -- III: stellar and gas kinematics [PDF]

, 2019
We investigate the effects of Active Galactic Nuclei (AGN) on the gas kinematics of their host galaxies, using MaNGA data for a sample of 62 AGN hosts and 109 control galaxies (inactive galaxies).
