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…
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…
Synthetic light cone catalogues of modern redshift and weak lensing surveys with AbacusSummit
Boryana Hadzhiyska, Sihan Yuan, Chris Blake +32
The joint analysis of different cosmological probes, such as galaxy clustering and weak lensing, can potentially yield invaluable insights into the nature of the primordial Univers…
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,…
A data compression and optimal galaxy weights scheme for Dark Energy Spectroscopic Instrument and weak lensing datasets
Rossana Ruggeri, Chris Blake, Joseph DeRose +23
Combining different observational probes, such as galaxy clustering and weak lensing, is a promising technique for unveiling the physics of the Universe with upcoming dark energy e…
The Outer Stellar Mass of Massive Galaxies: A Simple Tracer of Halo Mass with Scatter Comparable to Richness and Reduced Projection Effects
Song Huang, Alexie Leauthaud, Christopher Bradshaw +7
Using the weak gravitational lensing data from the Hyper Suprime-Cam Subaru Strategic Program (HSC survey), we study the potential of different stellar mass estimates in tracing ha…
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…
Stellar and Weak Lensing Profiles of Massive Galaxies in the Hyper-Suprime Cam Survey and in Hydrodynamic Simulations
Felipe Ardila, Song Huang, Alexie Leauthaud +11
We perform a consistent comparison of the mass and mass profiles of massive () central galaxies at z~0.4 from deep Hyper Suprime-Cam (HSC) observation…
How Accurately Can We Detect the Splashback Radius of Dark Matter Halos and its Correlation With Accretion Rate?
Enia Xhakaj, Benedikt Diemer, Alexie Leauthaud +5
The splashback radius () of dark matter halos has recently been detected using weak gravitational lensing and cross-correlations with galaxies. However, different metho…
The Old Host-Galaxy Environment of SSS17a, the First Electromagnetic Counterpart to a Gravitational Wave Source
Y. -C. Pan, C. D. Kilpatrick, J. D. Simon +16
We present an analysis of the host-galaxy environment of Swope Supernova Survey 2017a (SSS17a), the discovery of an electromagnetic counterpart to a gravitational wave source, GW17…
Leveraging waveform complexity for confident detection of gravitational waves
Jonah B. Kanner, Tyson B. Littenberg, Neil Cornish +6
The recent completion of Advanced LIGO suggests that gravitational waves (GWs) may soon be directly observed. Past searches for gravitational-wave transients have been impacted by…
