Full forward model of galaxy clustering statistics with AbacusSummit lightcones
Sihan Yuan, Boryana Hadzhiyska, Tom Abel
Novel summary statistics beyond the standard 2-point correlation function (2PCF) are necessary to capture the full astrophysical and cosmological information from the small-scale (…
Illustrating galaxy-halo connection in the DESI era with IllustrisTNG
Sihan Yuan, Boryana Hadzhiyska, Sownak Bose +1
We employ the hydrodynamical simulation IllustrisTNG to inform the galaxy-halo connection of the Luminous Red Galaxy (LRG) and Emission Line Galaxy (ELG) samples of the Dark Energy…
Stringent constraints from small-scale galaxy clustering using a hybrid MCMC+emulator framework
Sihan Yuan, Lehman H. Garrison, Daniel J. Eisenstein +1
We present a novel simulation-based hybrid emulator approach that maximally derives cosmological and Halo Occupation Distribution (HOD) information from non-linear galaxy clusterin…
