Corrfunc --- A Suite of Blazing Fast Correlation Functions on the CPU
Manodeep Sinha, Lehman H. Garrison
The two-point correlation function (2PCF) is the most widely used tool for quantifying the spatial distribution of galaxies. Since the distribution of galaxies is determined by gal…
A Hybrid Deep Learning Approach to Cosmological Constraints From Galaxy Redshift Surveys
Michelle Ntampaka, Daniel J. Eisenstein, Sihan Yuan +1
We present a deep machine learning (ML)-based technique for accurately determining and from mock 3D galaxy surveys. The mock surveys are built from the AbacusCosmos sui…
Cosmology with galaxy-galaxy lensing on non-perturbative scales: Emulation method and application to BOSS LOWZ
Benjamin D. Wibking, David H. Weinberg, Andrés N. Salcedo +5
We describe our nonlinear emulation (i.e., interpolation) framework that combines the halo occupation distribution (HOD) galaxy bias model with -body simulations of nonlinear st…
KELT-24b: A 5M Planet on a 5.6 day Well-Aligned Orbit around the Young V=8.3 F-star HD 93148
Joseph E. Rodriguez, Jason D. Eastman, George Zhou +76
We present the discovery of KELT-24 b, a massive hot Jupiter orbiting a bright (V=8.3 mag, K=7.2 mag) young F-star with a period of 5.6 days. The host star, KELT-24 (HD 93148), has…
Generating Approximate Halo Catalogs for Blind Challenges in Precision Cosmology
Lehman H. Garrison, Daniel J. Eisenstein
We present a method for generating suites of dark-matter halo catalogs with only a few -body simulations, focusing on making small changes to the underlying cosmology of a simul…
