Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

Active galactic nuclei (AGN) are powered by the accretion of material onto a supermassive
black hole (SMBH) and are among the most luminous objects in the Universe. However, the …

The Dark Energy Spectroscopic Instrument (DESI) completed its 5 month Survey Validation
in 2021 May. Spectra of stellar and extragalactic targets from Survey Validation constitute …

The quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-
messenger era is compelling. Detecting dual active galactic nuclei (AGN)–active SMBHs at …

The relative positions of the high and low surface brightness regions of radio-loud active
galaxies in the 3CR sample were found by Fanaroff and Riley to be correlated with their …

We present integral field unit observations covering the [o iii] λλ4959, 5007 and Hβ emission
lines of 16 z< 0.2 type 2 active galactic nuclei (AGN). Our targets are selected from a well …

We present two large catalogs of active galactic nucleus (AGN) candidates identified across
30,093 deg 2 of extragalactic sky from the Wide-field Infrared Survey Explorer's AllWISE …

Stern et al. presented a study of Wide-field Infrared Survey Explorer (WISE) selection of
active galactic nuclei (AGNs) in the 2 deg 2 COSMOS field, finding that a simple criterion W1 …

We constructed a sample of 23 344 radio-loud active galactic nuclei (RLAGN) from the
catalogue derived from the LOFAR Two-Metre Sky Survey (LoTSS) survey of the HETDEX …
