Illuminating the Physics of Dark Energy with the Discovery Simulations
Gillian D. Beltz-Mohrmann, Adrian Pope, Alex Alarcon +10
In this paper, we present the Discovery simulations: a new pair of high-resolution N-body simulations motivated by the DESI Y1 BAO cosmological constraints on dark energy. The Disc…

Galaxy assembly bias in the stellar-to-halo mass relation for red central galaxies from SDSS
Grecco A. Oyarzún, Jeremy L. Tinker, Kevin Bundy +2
We report evidence of galaxy assembly bias - the correlation between galaxy properties and biased secondary halo properties at fixed halo mass (M) - in the stellar-to-halo mass…

Systematic Effects in Galaxy-Galaxy Lensing with DESI
J. U. Lange, C. Blake, C. Saulder +56
The Dark Energy Spectroscopic Instrument (DESI) survey will measure spectroscopic redshifts for millions of galaxies across roughly of the sky. Cross-cor…
