Which Milky Way Streams Make the Best Dark Matter Detectors?
Vedant Chandra, Charlie Conroy, Risa Wechsler +7
The abundance and properties of low-mass dark matter subhalos can be inferred by measuring the density and velocity structure of stellar streams, testing physical models of dark ma…
Novel Challenges in Tracking Self-Interacting Dark Matter Subhalos
Demao Kong, Hai-Bo Yu, Ethan O. Nadler +2
Cosmological N-body simulations are among the primary tools for studying structure formation in the Universe. Analyses of these simulations critically depend on accurately identify…
Merger Response of Halo Anisotropy Properties
Kuan Wang, Philip Mansfield, Dhayaa Anbajagane +1
Anisotropy properties -- halo spin, shape, position offset, velocity offset, and orientation -- are an important family of dark matter halo properties that indicate the level of di…
Symfind: Addressing the Fragility of Subhalo Finders and Revealing the Durability of Subhalos
Philip Mansfield, Elise Darragh-Ford, Yunchong Wang +2
A major question in CDM is what this theory actually predicts for the properties of subhalo populations. Subhalos are difficult to simulate and to find within simulations, and t…
Haunted haloes: tracking the ghosts of subhaloes lost by halo finders
Benedikt Diemer, Peter Behroozi, Philip Mansfield
Dark matter subhaloes are key for the predictions of simulations of structure formation, but their existence frequently ends prematurely due to two technical issues, namely numeric…
MultiCAM: A multivariable framework for connecting the mass accretion history of haloes with their properties
Ismael Mendoza, Philip Mansfield, Kuan Wang +1
Models that connect galaxy and halo properties often summarize a halo's mass accretion history (MAH) with a single value, and use this value as the basis for predictions. However,…
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…
Approximating Density Probability Distribution Functions Across Cosmologies
Huanqing Chen, Nickolay Y. Gnedin, Philip Mansfield
Using a suite of self-similar cosmological simulations, we measure the probability distribution functions (PDFs) of real-space density, redshift-space density, and their geometric…
How Biased Are Halo Properties in Cosmological Simulations?
Philip Mansfield, Camille Avestruz
Cosmological N-body simulations have been a major tool of theorists for decades, yet many of the numerical issues that these simulations face are still unexplored. This paper measu…
Debiased Galaxy Cluster Pressure Profiles from X-ray Observations and Simulations
Yizhou He, Philip Mansfield, Markus M. Rau +2
We present an updated model for the average cluster pressure profile, adjusted for hydrostatic mass bias by combining results from X-ray observations with cosmological simulations.…
The Sheet of Giants: Unusual Properties of the Milky Way's Immediate Neighbourhood
Maria K. Neuzil, Philip Mansfield, Andrey V. Kravtsov
We quantify the shape and overdensity of the galaxy distribution in the `Local Sheet' within a sphere of Mpc, and compare these properties with the expectations of the CDM…
The Three Causes of Low-Mass Assembly Bias
Philip Mansfield, Andrey V. Kravtsov
We present a detailed analysis of the physical processes that cause halo assembly bias -- the dependence of halo clustering on proxies of halo formation time. We focus on the origi…
The splashback radius of halos from particle dynamics. II. Dependence on mass, accretion rate, redshift, and cosmology
Benedikt Diemer, Philip Mansfield, Andrey V. Kravtsov +1
The splashback radius , the apocentric radius of particles on their first orbit after falling into a dark matter halo, has recently been suggested as a physically motiv…
Splashback Shells of Cold Dark Matter Halos
Philip Mansfield, Andrey V. Kravtsov, Benedikt Diemer
The density field in the outskirts of dark matter halos is discontinuous due to a caustic formed by matter at its first apocenter after infall. In this paper, we present an algorit…
SCORCH I: The Galaxy-Halo Connection in the First Billion Years
Hy Trac, Renyue Cen, Philip Mansfield
SCORCH (Simulations and Constructions of the Reionization of Cosmic Hydrogen) is a new project to study the Epoch of Reionization (EoR). In this first paper, we probe the connectio…
