Probing the Reionization History and Bubble Sizes with JWST Lyman- Fraction Measurements
Aritra Kundu, Adam Lidz, Guochao Sun
Recent James Webb Space Telescope (JWST) measurements quantify the fraction of ultraviolet-selected galaxies showing detectable Lyman-alpha (Ly-) lines at . These L…
LIMFAST. V. Probing Reionization with the Synergy Between 21 cm and Photometric Galaxy Surveys
Guochao Sun, Adam Lidz, Tzu-Ching Chang +4
Cross-correlating the 21\,cm signal from intergalactic neutral hydrogen with the galaxy distribution is a powerful probe of the Epoch of Reionization and the physical mechanisms dr…
The Dynamics of Old Inner Galaxy Stars in Milky Way-mass Galaxies Using FIRE-2 Simulations
Emma Tasso, Madeline Lucey, Robyn Sanderson +2
Understanding how galaxies like the Milky Way assembled over cosmic time remains a central question in astrophysics. Understanding the processes that shaped their formation and evo…
Probing Atomic Dark Matter with Stellar Streams in Milky Way-Mass Galaxies
Lucas S. Mandacarú Guerra, Stephanie O'Neil, Mariangela Lisanti +7
We present the first detailed analysis of the effects of dissipative dark matter on stellar streams. As a concrete example, we generate a cosmological hydrodynamic zoom-in simulati…
