Silencing the Giant: Evidence of Active Galactic Nucleus Feedback and Quenching in a Little Red Dot at z = 4.13

Astrophysical Journal
The James Webb Space Telescope (JWST) has uncovered a ubiquitous population of dust-obscured compact sources at z ≳ 4. Many of these objects exhibit signs of active galactic nucleus (AGN) activity, making their study crucial for understanding the ...

A Study on Active Galactic Nucleus Variability

2022
Active Galactic Nuclei (AGNs) are accreting supermassive black holes at the center of galaxies, known for rich spectral features and multi-time scale variability in their electromagnetic emission. The origin of the variability in AGN light curves can be either intrinsic, meaning related processes that take place inside the AGN system, or extrinsic, i.e.

IC4553: Masers Around an Active Galactic Nucleus

Publications of the Astronomical Society of Australia, 1984
AbstractThe galaxy IC4553 (Arp 220) is a peculiar galaxy having a redshift of 0.02. It has been variously described as consisting of a symbiotic pair of galaxies, as having a highly peculiar pair of nuclei, or as consisting of a nucleus bisected by a dust lane. In addition, it exhibits OH maser emission which is both the most intrinsically luminous (by

A galactic model with a pulsating active nucleus. I

Astrophysics and Space Science, 1973
The chemical evolution of the Galaxy with a pulsating active nucleus is investigated. The surface densities of gas, stellar remnants, stars and chemical species such as helium and heavy elements inZ≧6 are calculated as functions of the position in the Galaxy and of the evolutional time of the Galaxy.
