A machine learning-based method for populating dark matter halos in N-body simulations with substructure
Milad Noorikuhani, Jeremy Tinker
Dark matter N-body simulations that resolve halo substructure (subhalos) with high accuracy can be used for generating reliable catalogs of central and satellite galaxies via galax…
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…
Aemulus : Precise Predictions for Matter and Biased Tracer Power Spectra in the Presence of Neutrinos
Joseph DeRose, Nickolas Kokron, Arka Banerjee +6
We present the Aemulus simulations: a suite of 150 -body simulations with a mass resolution of $3.51\times 10^{10} \frac{Ω_{cb}}{0.3} ~ h^{-1} M_{\o…
Abundance matching analysis of the emission line galaxy sample in the extended Baryon Oscillation Spectroscopic Survey
Sicheng Lin, Jeremy L. Tinker, Michael R. Blanton +4
We present the measurements of the small-scale clustering for the emission line galaxy (ELG) sample from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) in the Sloan D…
The Aemulus Project VI: Emulation of beyond-standard galaxy clustering statistics to improve cosmological constraints
Kate Storey-Fisher, Jeremy Tinker, Zhongxu Zhai +3
There is untapped cosmological information in galaxy redshift surveys in the non-linear regime. In this work, we use the AEMULUS suite of cosmological -body simulations to const…
DESI Bright Galaxy Survey: Final Target Selection, Design, and Validation
ChangHoon Hahn, Michael J. Wilson, Omar Ruiz-Macias +57
Over the next five years, the Dark Energy Spectroscopic Instrument (DESI) will use 10 spectrographs with 5000 fibers on the 4m Mayall Telescope at Kitt Peak National Observatory to…
