Journal ArticleDOI
Cosmological constraints from galaxy clustering and the mass-to-number ratio of galaxy clusters: marginalizing over the physics of galaxy formation
Rachel M. Reddick,Rachel M. Reddick,Jeremy L. Tinker,Risa H. Wechsler,Risa H. Wechsler,Yu Lu,Yu Lu +6 more
TL;DR: In this article, the authors used a Halo Occupancy Distribution (HOD) to estimate the cosmological parameters of a galaxy, and then used the observables in each model, marginalizing over the parameters of the HOD.

TL;DR: In this paper, the authors were honored to conduct astronomical research on Iolkam Du'ag (Kitt Peak), a mountain with particular significance to the Tohono O'odham Nation.
Journal ArticleDOI
Signatures of Velocity-dependent Dark Matter Self-interactions in Milky Way-mass Halos
Ethan O. Nadler,Arka Banerjee,Arka Banerjee,Susmita Adhikari,Yao-Yuan Mao,Risa H. Wechsler,Risa H. Wechsler +6 more
TL;DR: In this article, the authors explore the impact of elastic, anisotropic, velocity-dependent dark matter self-interactions on the host halo and subhalos of Milky Way (MW) mass systems.
Journal ArticleDOI
The Las Campanas Distant Cluster Survey -- The Correlation Function
TL;DR: In this paper, the authors measured the angular correlation function for velocity-dispersion limited subsamples of the Las Campanas Distant Cluster Survey (LCDCS) at estimated redshifts of 0.35
Journal ArticleDOI

TL;DR: In this article, the authors proposed to use the cross-correlation data to calibrate photometric redshift biases while marginalizing over possible clustering bias evolution in either the calibration or unknown photometric samples.
