We report a new changing-look quasar, WISE J105203. 55+ 151929.5 at z= 0.303, found by
identifying highly mid-IR-variable quasars in the Wide-field Infrared Survey Explorer …

Type 2 active galactic nuclei (AGNs) show signatures of accretion onto a supermassive
black hole through strong, high-ionization, narrow emission lines extended on scales of …

In order to better understand how active galactic nuclei (AGNs) affect the interstellar media
of their host galaxies, we perform a meta-analysis of the CO emission for a sample of z= 0.01 …

In this paper, we investigate 2727 galaxies observed by MaNGA as of 2016 June to develop
spatially resolved techniques for identifying signatures of active galactic nuclei (AGNs). We …

Major mergers between galaxies are predicted to fuel their central supermassive black holes
(SMBHs), particularly after coalescence. However, determining the prevalence of active …

Arp 187 is one of the fading active galactic nuclei (AGNs), whose AGN activity is currently
decreasing in luminosity. We investigate the observational signatures of AGN in Arp 187 …

The size and structure of the dusty circumnuclear torus in active galactic nuclei (AGNs) can
be investigated by analyzing the temporal response of the torus's infrared (IR) dust emission …

Recent mid-infrared high spatial resolution observations have revealed that active galactic
nuclei (AGNs) may host a polar dust region with the size of several pc, and such dust may be …

Massive large-scale active galactic nucleus (AGN) outflows are an important element of
galaxy evolution, being a way through which the AGN can affect most of the host galaxy …

We examine the long-term optical/near-infrared (NIR) flux variability of a 'changing-
look'active galactic nucleus (AGN) Mrk 590 between 1998 and 2007. Multiband multi-epoch …
