Tidal disruption of solitons in self-interacting ultralight axion dark matter

Glennon, Noah; Nadler, Ethan O.; Musoke, Nathan; BANERJEE, ARKA; Prescod-Weinstein, Chanda; Wechsler, Risa H. (American Physical Society, 2022-06)

Ultralight axions (ULAs) are promising dark matter candidates that can have a distinct impact on the formation and evolution of structure on nonlinear scales relative to the cold, collisionless dark matter (CDM) paradigm. ...
The Aemulus Project. V. Cosmological Constraint from Small-scale Clustering of BOSS Galaxies

Zhai, Zhongxu; Tinker, Jeremy L.; BANERJEE, ARKA; DeRose, Joseph; Guo, Hong; Mao, Yao-Yuan; McLaughlin, Sean; Storey-Fisher, Kate; Wechsler, Risa H. (IOP Publishing, 2023-05)

We analyze clustering measurements of BOSS galaxies using a simulation-based emulator of two-point statistics. We focus on the monopole and quadrupole of the redshift-space correlation function, and the projected correlation ...
Buzzard to Cardinal: Improved Mock Catalogs for Large Galaxy Surveys

To, Chun-Hao; DeRose, Joseph; Wechsler, Risa H.; Rykoff,Eli; Wu, Hao-Yi; ADHIKARI, SUSMITA; Krause, Elisabeth; Rozo, Eduardo; Weinberg, David H (IOP Publishing, 2024-01)

We present the Cardinal mock galaxy catalogs, a new version of the Buzzard simulation that has been updated to support ongoing and future cosmological surveys, including the Dark Energy Survey (DES), DESI, and LSST. These ...
