Quenching star formation with low-luminosity AGN winds
Ivan Almeida, Rodrigo Nemmen, Rogemar A. Riffel
We present a simple model for low-luminosity active galactic nucleus (LLAGN) feedback through winds produced by a hot accretion flow. The wind carries considerable energy and depos…
Active Galactic Nuclei signatures in Red Geyser galaxies from Gemini GMOS-IFU observations
G. S. Ilha, R. A. Riffel, T. V. Ricci +8
Red Geysers are quiescent galaxies with galactic scale ionised outflows, likely due to low-luminosity Active Galactic Nuclei (AGN). We used Gemini GMOS-IFU observations of the inne…
The Eddington ratio-dependent changing look events in NGC 2992
Muryel Guolo, Daniel Ruschel-Dutra, Dirk Grupe +5
We present an analysis of historical multi-wavelength emission of the Changing Look (CL) Active Galactic Nucleus (AGN) in NGC 2992, covering epochs ranging from 1978 to 2021, as we…
Deep learning model for multiwavelength emission from low-luminosity active galactic nuclei
Ivan Almeida, Roberta Duarte, Rodrigo Nemmen
Most active supermassive black holes (SMBH) in present-day galaxies are underfed and consist of low-luminosity active galactic nuclei (LLAGN). They have multiwavelength broadband s…
On the relation between mini-halos and AGN feedback in clusters of galaxies
A. Richard-Laferrière, J. Hlavacek-Larrondo, R. S. Nemmen +10
A variety of large-scale diffuse radio structures have been identified in many clusters with the advent of new state-of-the-art facilities in radio astronomy. Among these diffuse r…
VLT/SINFONI study of black hole growth in high redshift radio-loud quasars from the CARLA survey
M. Marinello, R. A. Overzier, H. J. A. Röttgering +11
We present VLT/SINFONI observations of 35 quasars at 2.1 < z < 3.2, the majority of which were selected from the Clusters Around Radio-Loud AGN (CARLA) survey. CARLA quasars have l…
