Probing the Physics of Dusty Outflows through Complex Organic Molecules in the Early Universe
Andrey Vayner, Tanio DÃaz-Santos, Carl D. Ferkinhoff +22
Galaxy-scale outflows are of critical importance for galaxy formation and evolution. Dust grains are the main sites for the formation of molecules needed for star formation but are…
Hot Diggity Dog: Simultaneous CO and Dust Modeling of the Most Luminous WISE Hot Dust-Obscured Galaxy Unveils Extreme Molecular Gas Excitation
Kevin C. Harrington, Román Fernández Aranda, Leindert Boogaard +7
Hot dust-obscured galaxies (Hot DOGs), the most infrared (IR) luminous objects selected by the WISE all-sky mid-IR survey, have yielded a sample of intrinsically luminous quasars (…
Investigating Little Red Dots with UV Excess: Are They the High-Redshift Siblings of Blue Hot DOGs?
Lulu Bao, Chao-Wei Tsai, Jingwen Wu +7
Little Red Dots (LRDs), newly identified compact and dusty galaxies with an unexpectedly high number density observed by JWST, have an unusual "V-shaped" rest-frame UV to near-infr…
Discovery and characterization of 25 new quasars at 4.6 < z < 6.9 from wide-field multi-band surveys
Silvia Belladitta, Eduardo Bañados, Zhang-Liang Xie +18
Luminous quasars at provide key insights into the early Universe. Their rarity necessitates wide-field multi-band surveys to efficiently separate them from the main astrophys…
Powerful nuclear outflows and circumgalactic medium shocks driven by the most luminous known obscured quasar in the Universe
Andrey Vayner, Tanio DÃaz-Santos, Peter R. M. Eisenhardt +18
We report integral field spectroscopy observations with the Near-Infrared Spectrograph on board JWST targeting the 60 kpc environment surrounding the most luminous obscured quasar…
Multi-Component Ionized Gas Outflows in a Hot Dust-Obscured Galaxy W2026+0716 with Keck/OSIRIS
Chao Liu, Chao-Wei Tsai, Peter R. M. Eisenhardt +15
We present narrowband-filtered integral field unit (IFU) observations of the Hot Dust-Obscured Galaxy (Hot DOG) WISE J202615.27071624.0 (hereafter W20260716) at redshift $z=2…
