The hyperluminous X‐ray source population
Astronomische Nachrichten, Volume 344, Issue 4, May 2023., 2023 Abstract We have recently published a catalog of 1843 candidate ultraluminous X‐ray sources (ULXs). This is the largest catalog of ULXs to date and was built by cross‐correlating recent serendipitous source catalogs from the XMM‐Newton, Swift, and Chandra observatories with a large sample of galaxies, primarily from HyperLEDA.

Cosmic Sands: The Origin of Dusty, Star-forming Galaxies in the Epoch of Reionization
The Astrophysical Journal, 2023 We present the Cosmic Sands suite of cosmological zoom-in simulations based on the simba galaxy formation model in order to study the buildup of the first massive and dusty galaxies in the early universe.

The submillimetre properties of ultraluminous infrared galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We present the results of SCUBA observations of a complete sample of local ULIRGs. Twenty of the initial sample of 23 sources are detected at 850 um and nearly half of the objects are also detected at 450 um. This data is combined with existing observations of a further seven ULIRGs to produce the largest sample of submm observations of ULIRGs ...

Discovery of a Low-redshift Hot Dust-obscured Galaxy
The Astrophysical Journal, 2023 We report the discovery of the hyperluminous, highly obscured active galactic nuclei (AGN) WISE J190445.04+485308.9 (W1904+4853, hereafter, L _bol ∼ 1.1 × 10 ^13 L _⊙ ) at z = 0.415.

Hidden Quasars in Ultraluminous Infrared Galaxies [PDF]
Symposium - International Astronomical Union, 1999 Many ultraluminous infrared galaxies (ULIRGs) are powered by quasars hidden in the center, but many are also powered by starbursts. A simply diagnostic diagram is proposed that can identify obscured quasars in ULIRGs by their high-ionization emission lines ([O III]λ5007/Hβ ≳ 5), and “warm” IR color (f25/f60≳ 0.25).

Ultraluminous infrared galaxies and the origin of quasars [PDF]
The Astrophysical Journal, 1988 The Infrared Astronomical Satellite (IRAS) has discovered a class of ultraluminous infrared galaxies (L ir > 1012 L ⊙) that are bolometrically as luminous, and slightly more numerous than optically selected quasars in the local universe (z ≲ 0.2).

A Near-infrared-faint, Far-infrared-luminous Dusty Galaxy at z ∼ 5 in COSMOS-Web
The Astrophysical Journal, 2023 A growing number of far-infrared (FIR) bright sources completely invisible in deep extragalactic optical surveys hint at an elusive population of z > 4 dusty, star-forming galaxies.

Energetic nuclear transients in luminous and ultraluminous infrared galaxies [PDF]
Astronomy & Astrophysics, 2022 Energetic nuclear outbursts have been discovered in luminous and ultraluminous infrared galaxies (U/LIRGs) at unexpectedly high rates. To investigate this population of transients, we performed a search in mid-IR data from the Wide-field Infrared Survey Explorer (WISE) satellite and its NEOWISE survey to detect and characterise luminous and smoothly ...
