Lagrangian Bias as a Gaussian Random Field
Arka Banerjee
Halo bias is typically treated as a set of coefficients in a perturbative expansion. We show instead that every point in a Gaussian density field has a well-defined scale-independe…
Joint analysis of small-scale galaxy clustering and galaxy--galaxy lensing from BOSS galaxies
Wenhao Gao, Zhenjie Liu, Zhongxu Zhai +8
We present a joint analysis of galaxy clustering and galaxy--galaxy lensing measurements from BOSS galaxies using a simulation-based emulation method combined with a halo occupatio…
N-body Simulations of cosmologies with Light Massive Relics
Vikhyat Sharma, Arka Banerjee
The presence of additional relativistic particles at the time of recombination can be inferred through their contribution to . If these species have a finite but low…
Aemulus : Precision halo mass functions in wCDM cosmologies
Delon Shen, Nickolas Kokron, Joseph DeRose +4
Precise and accurate predictions of the halo mass function for cluster mass scales in cosmologies are crucial for extracting robust and unbiased cosmological informat…
