Subhalos are Anisotropically Distributed and Aligned with the Smooth Matter Distribution of Their Host Halos
Lorena Mezini, Andrew R. Zentner, Kuan Wang +1
We investigate the distributions of subhalos about their hosts in two suites of zoom-in N-body simulations of halo growth -- one suite focused on Milky Way-Mass halos ($\sim 10^{12…
The DESI One-Percent Survey: Evidence for Assembly Bias from Low-Redshift Counts-in-Cylinders Measurements
Alan N. Pearl, Andrew R. Zentner, Jeffrey A. Newman +28
We explore the galaxy-halo connection information that is available in low-redshift samples from the early data release of the Dark Energy Spectroscopic Instrument (DESI). We model…
The Influence of Subhaloes on Host Halo Properties
Lorena Mezini, Catherine E. Fielder, Andrew R. Zentner +3
Within the CDM cosmology, dark matter haloes are comprised of both a smooth component and a population of smaller, gravitationally bound subhaloes. These components are often tr…
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,…
Evidence of Galaxy Assembly Bias in SDSS DR7 Galaxy Samples from Count Statistics
Kuan Wang, Yao-Yuan Mao, Andrew R. Zentner +4
We present observational constraints on the galaxy-halo connection, focusing particularly on galaxy assembly bias, from a novel combination of counts-in-cylinders statistics, $P(N_…
Concentrations of Dark Haloes Emerge from Their Merger Histories
Kuan Wang, Yao-Yuan Mao, Andrew R. Zentner +3
The concentration parameter is a key characteristic of a dark matter halo that conveniently connects the halo's present-day structure with its assembly history. Using 'Dark Sky', a…
Cosmological Evidence Modelling: a new simulation-based approach to constrain cosmology on non-linear scales
Johannes U. Lange, Frank C. van den Bosch, Andrew R. Zentner +3
Extracting accurate cosmological information from galaxy-galaxy and galaxy-matter correlation functions on non-linear scales () requires cosmologic…
How to Optimally Constrain Galaxy Assembly Bias: Supplement Projected Correlation Functions with Count-in-cells Statistics
Kuan Wang, Yao-Yuan Mao, Andrew R. Zentner +6
Most models for the connection between galaxies and their haloes ignore the possibility that galaxy properties may be correlated with halo properties other than mass, a phenomenon…
Updated Results on the Galaxy-Halo Connection from Satellite Kinematics in SDSS
Johannes U. Lange, Frank C. van den Bosch, Andrew R. Zentner +2
We present new results on the relationship between central galaxies and dark matter haloes inferred from observations of satellite kinematics in the Sloan Digital Sky Survey (SDSS)…
Maturing Satellite Kinematics into a Competitive Probe of the Galaxy-Halo Connection
Johannes U. Lange, Frank C. van den Bosch, Andrew R. Zentner +2
The kinematics of satellite galaxies moving in a dark matter halo are a direct probe of the underlying gravitational potential. Thus, the phase-space distributions of satellites re…
The Immitigable Nature of Assembly Bias: The Impact of Halo Definition on Assembly Bias
Antonia S. Villarreal, Andrew R. Zentner, Yao-Yuan Mao +6
Dark matter halo clustering depends not only on halo mass, but also on other properties such as concentration and shape. This phenomenon is known broadly as assembly bias. We explo…
