The Concentration-Mass Relation of Massive, Dynamically Relaxed Galaxy Clusters: Agreement Between Observations and CDM Simulations
Elise Darragh-Ford, Adam B. Mantz, Elena Rasia +5
The relationship linking a galaxy cluster's total mass with the concentration of its mass profile and its redshift is a fundamental prediction of the Cold Dark Matter (CDM) paradig…
: Mapping Vertical Phase Spiral Characteristics Throughout the Real and Simulated Milky Way
Elise Darragh-Ford, Jason A. S. Hunt, Adrian M. Price-Whelan +1
The recent discovery of a spiral pattern in the vertical kinematic structure in the solar neighborhood provides a prime opportunity to study non-equilibrium dynamics in the Milky W…
Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program
Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao +39
We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift ta…
Six More Ultra-Faint Milky Way Companions Discovered in the DECam Local Volume Exploration Survey
W. Cerny, C. E. Martínez-Vázquez, A. Drlica-Wagner +28
We report the discovery of six ultra-faint Milky Way satellites discovered through matched-filter searches conducted using Dark Energy Camera (DECam) data processed as part of the…
Symphony: Cosmological Zoom-in Simulation Suites over Four Decades of Host Halo Mass
Ethan O. Nadler, Philip Mansfield, Yunchong Wang +9
We present Symphony, a compilation of cosmological, cold-dark-matter-only zoom-in simulations spanning four decades of host halo mass, from $10^{15}~M_{\mathrm{\o…
Multiple phase spirals suggest multiple origins in Gaia DR3
Jason A. S. Hunt, Adrian M. Price-Whelan, Kathryn V. Johnston +1
{\it Gaia} Data Release 2 (DR2) revealed that the Milky Way contains significant indications of departures from equilibrium in the form of asymmetric features in the phase space de…
Signal in Noise: Exploring Meaning Encoded in Random Character Sequences with Character-Aware Language Models
Mark Chu, Bhargav Srinivasa Desikan, Ethan O. Nadler +3
Natural language processing models learn word representations based on the distributional hypothesis, which asserts that word context (e.g., co-occurrence) correlates with meaning.…
Snowmass2021 Cosmic Frontier White Paper: Prospects for obtaining Dark Matter Constraints with DESI
Monica Valluri, Solene Chabanier, Vid Irsic +29
Despite efforts over several decades, direct-detection experiments have not yet led to the discovery of the dark matter (DM) particle. This has led to increasing interest in altern…
From Images to Dark Matter: End-To-End Inference of Substructure From Hundreds of Strong Gravitational Lenses
Sebastian Wagner-Carena, Jelle Aalbers, Simon Birrer +4
Constraining the distribution of small-scale structure in our universe allows us to probe alternatives to the cold dark matter paradigm. Strong gravitational lensing offers a uniqu…
Characterization of the background spectrum in DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, I. Arnquist +31
We construct the first comprehensive radioactive background model for a dark matter search with charge-coupled devices (CCDs). We leverage the well-characterized depth and energy r…
Searching for Dwarf Galaxies in DR2 Phase-Space Data Using Wavelet Transforms
Elise Darragh-Ford, Ethan O. Nadler, Sean McLaughlin +1
We present a wavelet-based algorithm to identify dwarf galaxies in the Milky Way in DR2 data. Our algorithm detects overdensities in 4D position--proper motion space,…
Measurement of the bulk radioactive contamination of detector-grade silicon with DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, D. Baxter +28
We present measurements of bulk radiocontaminants in the high-resistivity silicon CCDs from the DAMIC at SNOLAB experiment. We utilize the exquisite spatial resolution of CCDs to d…
Constraints on Light Dark Matter Particles Interacting with Electrons from DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, D. Baxter +31
We report direct-detection constraints on light dark matter particles interacting with electrons. The results are based on a method that exploits the extremely low levels of leakag…
