Growing the First Galaxies' Merger Trees
Ethan O. Nadler, Andrew Benson, Trey Driskell +2
Modelling the growth histories of specific galaxies often involves generating the entire population of objects that arise in a given cosmology and selecting systems with appropriat…
Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program
Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao +39
We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift ta…
Novel Conservative Methods for Adaptive Force Softening in Collisionless and Multi-Species N-Body Simulations
Philip F. Hopkins, Ethan O. Nadler, Michael Y. Grudic +3
Modeling self-gravity of collisionless fluids (e.g. ensembles of dark matter, stars, black holes, dust, planetary bodies) in simulations is challenging and requires some force soft…
Strong Dark Matter Self-interactions Diversify Halo Populations within and surrounding the Milky Way
Daneng Yang, Ethan O. Nadler, Hai-Bo Yu
We perform a high-resolution cosmological zoom-in simulation of a Milky Way (MW)--like system, which includes a realistic Large Magellanic Cloud analog, using a large differential…
Six More Ultra-Faint Milky Way Companions Discovered in the DECam Local Volume Exploration Survey
W. Cerny, C. E. Martínez-Vázquez, A. Drlica-Wagner +28
We report the discovery of six ultra-faint Milky Way satellites discovered through matched-filter searches conducted using Dark Energy Camera (DECam) data processed as part of the…
Structure Formation and the Global 21-cm Signal in the Presence of Coulomb-like Dark Matter-Baryon Interactions
Trey Driskell, Ethan O. Nadler, Jordan Mirocha +6
Many compelling dark matter (DM) scenarios feature Coulomb-like interactions between DM particles and baryons, in which the cross section for elastic scattering scales with relativ…
