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 halo occupation distribution (HOD) from z = 0.1 to 0.3 using Surv

We present observational constraints on the galaxy-halo connection, focusing particularly on galaxy assembly bias, from a novel combination of counts-in-cylinders statistics, $P(N_{\rm{CIC}})$, with the standard measurements of the projected two-poin

Most of the dark matter (DM) search over the last few decades has focused on WIMPs, but the viable parameter space is quickly shrinking. Asymmetric Dark Matter (ADM) is a WIMP-like DM candidate with slightly smaller masses and no present day annihila

We investigate analytically whether in a close encounter with a star, a dark matter (DM) particle can be accelerated above the escape speed of a globular cluster and be ejected. We find that this mechanism is not sufficient to eject a massive, extend

We present a Bayesian hierarchical inference formalism (Basilisk) to constrain the galaxy-halo connection using satellite kinematics. Unlike traditional methods, Basilisk does not resort to stacking the kinematics of satellite galaxies in bins of cen

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 known as galaxy assembly bias. Yet, it is known that such correlations

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) DR7. We employ an updated analysis framework that includes detailed m

We constrain the newly-introduced decorated Halo Occupation Distribution (HOD) model using SDSS DR7 measurements of projected galaxy clustering or r-band luminosity threshold samples. The decorated HOD is a model for the galaxy-halo connection that a

Standard halo occupation distribution (HOD) models predict how galaxies occupy halos based on a single property, the virial mass, M vir. To incorporate galaxy assembly bias, we consider alternative halo mass proxies to use in the HOD. A promising rep

In the coming decade, a new generation of massively multiplexed spectroscopic surveys, such as the Prime Focus Spectrograph Galaxy Evolution Survey (PFS), Wide Area Vista Extragalactic Survey-Deep (WAVES), and Multi-Object Optical and Near-infrared S
