Investigating black hole accretion and feedback self-regulation in Seyfert galaxies using the FIRE-3 cosmological hydrodynamic simulations
Jonathan Mercedes-Feliz, Daniel Anglés-Alcázar, Jose Cevallos +12
Recent observations of local Seyfert galaxies show an intriguing connection between Active Galactic Nuclei (AGN) luminosity and a deficit of molecular gas on ~50pc scales compared…
Little Red Dots on FIRE: Exploring the formation and observational signatures of ultra-compact early galaxies
Niranjan Chandra Roy, Daniel Anglés-Alcázar, Rachel K. Cochrane +15
Little Red Dots (LRDs) are compact sources with broad Balmer lines, Balmer breaks, anomalous UV emission, rising red continuum, and uncertain origin. We use FIRE cosmological simul…
Little Red Dots on FIRE: The Ability of Bursty Galaxies to Host an Abundant Population of High-Redshift AGN
Andrew Marszewski, Claude-André Faucher-Giguère, Guochao Sun +5
The James Webb Space Telescope has unveiled an abundant population of potential active galactic nuclei (AGN) at high redshift () known as little red dots (LRDs), which a…
Deep and Sparse Denoising Benchmarks for Spectral Data Cubes of High-z Galaxies: From Simulations to ALMA observations
Arnab Lahiry, Tanio DÃaz-Santos, Jean-Luc Starck +4
Beyond cosmic noon, galaxies appear as faint whispers amid noise, yet this epoch is key to understanding massive galaxy assembly. ALMA's sensitivity to cold dust and [C II] emissio…
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…
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…
