Survivors and Zombies: The Quenching and Disruption of Satellites around Milky Way Analogs
Debosmita Pathak, Charlotte R. Christensen, Alyson M. Brooks +3
It is necessary to understand the full accretion history of the Milky Way in order to contextualize the properties of observed Milky Way satellite galaxies and the stellar halo. Th…
Testable predictions of outside-in age gradients in dwarf galaxies of all types
Claire L. Riggs, Alyson M. Brooks, Ferah Munshi +4
We use a sample of 73 simulated satellite and central dwarf galaxies spanning a stellar mass range of to investigate the origin of their stellar age gra…
The Role of Mass and Environment on Satellite distributions around Milky Way analogs in the Romulus25 simulation
Jordan Van Nest, Ferah Munshi, Charlotte Christensen +3
We study satellite counts and quenched fractions for satellites of Milky Way analogs in Romulus25, a large-volume cosmological hydrodynamic simulation. Depending on the definition…
Broad-line region in NGC 4151 monitored by two decades of reverberation mapping campaigns. I. Evolution of structure and kinematics
Yong-Jie Chen, Dong-Wei Bao, Shuo Zhai +33
We report the results of long-term reverberation mapping (RM) campaigns of the nearby active galactic nuclei (AGN) NGC 4151, spanning from 1994 to 2022, based on archived observati…
ALMA reveals extended cool gas and hot ionized outflows in a typical star-forming galaxy at
Hollis Akins, Seiji Fujimoto, Kristian Finlator +9
We present spatially-resolved morphological properties of [CII] 158 m, [OIII] 88 m, dust, and rest-frame ultraviolet (UV) continuum emission for A1689-zD1, a strongly lensed,…
High Molecular-Gas to Dust Mass Ratios Predicted in Most Quiescent Galaxies
Katherine E. Whitaker, Desika Narayanan, Christina C. Williams +15
Observations of cold molecular gas reservoirs are critical for understanding the shutdown of star formation in massive galaxies. While dust continuum is an efficient and affordable…
