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…

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…

Redshift evolution and covariances for joint lensing and clustering studies with DESI Y1

Sihan Yuan, Chris Blake, Alex Krolewski +48

Galaxy-galaxy lensing (GGL) and clustering measurements from the Dark Energy Spectroscopic Instrument Year 1 (DESI Y1) dataset promise to yield unprecedented combined-probe tests o…

Cluster Cosmology Without Cluster Finding

Enia Xhakaj, Alexie Leauthaud, Johannes Lange +5

We propose that observations of super-massive galaxies contain cosmological constraining power similar to conventional cluster cosmology, and we provide promising indications that…

Constraints on from a full-scale and full-shape analysis of redshift-space clustering and galaxy-galaxy lensing in BOSS

Johannes U. Lange, Andrew P. Hearin, Alexie Leauthaud +5

We present a novel simulation-based cosmological analysis of galaxy-galaxy lensing and galaxy redshift-space clustering. Compared to analysis methods based on perturbation theory,…

Beyond Mass: Detecting Secondary Halo Properties with Galaxy-Galaxy Lensing

Enia Xhakaj, Alexie Leauthaud, Johannes Lange +3

Secondary halo properties beyond mass, such as the mass accretion rate (MAR), concentration, and the half mass scale, are essential in understanding the formation of large-scale st…
