ELGLRG distribution through dark matter halo dynamics
Ginevra Favole, Francisco-Shu Kitaura, Boryana Hadzhiyska +3
We investigate the clustering and halo occupation distribution (HOD) of DESI Y1 emission-line (ELGs) and luminous red (LRGs) galaxies at , including their cross-correlat…
Field-Level Comparison and Robustness Analysis of Cosmological N-body Simulations
Adrian E. Bayer, Francisco Villaescusa-Navarro, Sammy Sharief +6
We present the first field-level comparison of cosmological N-body simulations, considering various widely used codes: Abacus, CUBEPM, Enzo, Gadget, Gizmo, PKDGrav, and Ramses.…
nifty-ls: Fast and Accurate Lomb-Scargle Periodograms Using a Non-Uniform FFT
Lehman H. Garrison, Dan Foreman-Mackey, Yu-hsuan Shih +1
We present nifty-ls, a software package for fast and accurate evaluation of the Lomb-Scargle periodogram. nifty-ls leverages the fact that Lomb-Scargle can be computed using a non-…
Self-Similar Mass Accretion History in Scale-Free Simulations
John Soltis, Lehman Garrison
Using a scale-free -body simulation generated with the ABACUS -body code, we test the robustness of halo mass accretion histories via their convergence to self-similarity. We…
AbacusPNG: A modest set of simulations of local-type primordial non-Gaussianity in the DESI era
Boryana Hadzhiyska, Lehman Garrison, Daniel J. Eisenstein +1
A measurement of a primordial non-Gaussianity (PNG) signal through late- or early-Universe probes has the potential to transform our understanding of the physics of the primordial…
On the co-rotation of Milky Way satellites: LMC-mass satellites induce apparent motions in outer halo tracers
Nicolas Garavito-Camargo, Adrian M. Price-Whelan, Jenna Samuel +8
Understanding the physical mechanism behind the formation of a co-rotating thin plane of satellite galaxies, like the one observed around the Milky Way (MW), has been challenging.…
