EmpiriciSN: Re-sampling Observed Supernova/Host Galaxy Populations using an XD Gaussian Mixture Model
Thomas W.-S. Holoien,Philip J. Marshall,Philip J. Marshall,Risa H. Wechsler,Risa H. Wechsler +4 more
TL;DR: EmpiriciSN is an example application of this functionality that can be used for fitting an XDGMM model to observed supernova/host datasets and predicting likely supernova parameters using on a model conditioned on observed host properties.

The Aemulus Project IV: Emulating Halo Bias
Thomas McClintock,Thomas McClintock,Eduardo Rozo,Arka Banerjee,Matthew R. Becker,Matthew R. Becker,Joseph DeRose,Sean McLaughlin,Jeremy L. Tinker,Risa H. Wechsler,Zhongxu Zhai,Zhongxu Zhai +11 more
TL;DR: This work presents a halo bias emulator for modeling the clustering of halos on large scales that incorporates the cosmological dependence of the bias beyond the mapping of halo mass to peak height.
Journal ArticleDOI
UniverseMachine: Predicting Galaxy Star Formation over Seven Decades of Halo Mass with Zoom-in Simulations
TL;DR: In this article, the authors apply the galaxy-halo connection model UniverseMachine to dark matter-only zoom-in simulations of isolated Milky Way (MW)-mass halos along with their parent cosmological simulations.

TL;DR: The first set of maps and band-merged catalog from the Herschel Stripe 82 Survey (HerS) was presented in this article. But this survey was designed to measure correlations with external tracers of the dark matter density field, either point-like (radio to X-ray) or extended (i.e., clusters and gravitational lensing) to measure the bias and redshift distribution of intensities of infrared-emitting dusty star-forming galaxies and AGN.
