Scattering from Dusty Outflows in Hot Dust-Obscured Galaxies with Blue Excess Emission
R. J. Assef, M. Stalevski, F. E. Bauer +15
(Context) Hot Dust-Obscured Galaxies (Hot DOGs) are a population of hyper-luminous quasars heavily obscured by dust and gas. While most have rest UV/optical SEDs dominated by their…
The eROSITA X-ray luminosity function of active galactic nuclei
W. Roster, J. Buchner, M. Salvato +23
The paper measures the soft X‑ray luminosity function of active galactic nuclei using eROSITA data across a wide luminosity and redshift range, introduces a redshift‑dependent brok…
An Exploratory Analysis of New Large Gaia-informed Quasar Samples in SDSS-V
Shir Aviram, Benny Trakhtenbrot, Tom Dwelly +22
The paper presents an exploratory analysis of a new all‑sky quasar catalog from SDSS‑V, using Gaia‑ and WISE‑based selection methods (GUA and Skewt‑QSO) that yield over 250,000 spe…
Project Hephaistos -- IV. James Webb Space Telescope Observations of Two Dyson Sphere Candidates
Erik Zackrisson, Arjan Bik, Anita Ali Asgar +11
We report on JWST/MIRI imaging and spectroscopy of two M-dwarf stars previously singled out by project Hephaistos as potential Dyson-sphere candidates (their candidates D and E) du…
Spatially resolved optical and mid-infrared spectroscopy of SDSS1335+0728: implications for the origin of the Ansky event
P. Sánchez-Sáez, M. Masterson, L. Hernández-GarcÃa +25
The galaxy SDSS1335+0728 brightened abruptly in December 2019 (the Ansky event) and has since been confirmed as the host of extreme X-ray quasi-periodic eruptions (QPEs) of debated…
Hidden Monsters with SPHEREx I: A goldmine for heavily reddened quasars at cosmic noon
Matthew Stepney, Manda Banerji, Franz E. Bauer +2
Heavily reddened quasars (HRQs) are luminous, dust-obscured broad-line quasars thought to represent a short-lived phase of intense black hole growth and feedback. Previous studies…
