DiffstarPop: A generative physical model of galaxy star formation history
Alex Alarcon, Andrew P. Hearin, Matthew R. Becker +3
We present DiffstarPop, a differentiable forward model of cosmological populations of galaxy star formation histories (SFH). In the model, individual galaxy SFH is parametrized by…
Illuminating the Physics of Dark Energy with the Discovery Simulations
Gillian D. Beltz-Mohrmann, Adrian Pope, Alex Alarcon +10
In this paper, we present the Discovery simulations: a new pair of high-resolution N-body simulations motivated by the DESI Y1 BAO cosmological constraints on dark energy. The Disc…
Redshift evolution and covariances for joint lensing and clustering studies with DESI Y1
Sihan Yuan, Chris Blake, Alex Krolewski +48
Galaxy-galaxy lensing (GGL) and clustering measurements from the Dark Energy Spectroscopic Instrument Year 1 (DESI Y1) dataset promise to yield unprecedented combined-probe tests o…
Toward Accurate Modeling of Galaxy Clustering on Small Scales: Halo Model Extensions and Lingering Tension
Gillian D. Beltz-Mohrmann, Adam O. Szewciw, Andreas A. Berlind +1
This paper represents an effort to provide robust constraints on the galaxy-halo connection and simultaneously test the Planck LCDM cosmology using a fully numerical model of small…
Toward Accurate Modeling of Galaxy Clustering on Small Scales: Constraining the Galaxy-Halo Connection with Optimal Statistics
Adam O. Szewciw, Gillian D. Beltz-Mohrmann, Andreas A. Berlind +1
Applying halo models to analyze the small-scale clustering of galaxies is a proven method for characterizing the connection between galaxies and their host halos. Such works are of…
The impact of baryonic physics on the abundance, clustering, and concentration of halos
Gillian D. Beltz-Mohrmann, Andreas A. Berlind
We examine the impact of baryonic physics on the halo distribution in hydrodynamic simulations (Illustris, IllustrisTNG, and EAGLE), particularly with regards to how it differs fro…
Radial Star Formation Histories in 32 Nearby Galaxies
Daniel A. Dale, Kristin R. Anderson, Louis M. Bran +10
The spatially resolved star formation histories are studied for 32 normal star-forming galaxies drawn from the the Spitzer Extended Disk Galaxy Exploration Science survey. At surfa…
Testing the Accuracy of Halo Occupation Distribution Modelling using Hydrodynamic Simulations
Gillian D. Beltz-Mohrmann, Andreas A. Berlind, Adam O. Szewciw
Halo models provide a simple and computationally inexpensive way to investigate the connection between galaxies and their dark matter haloes. However, these models rely on the assu…
Radial Star Formation Histories in Fifteen Nearby Galaxies
Daniel A. Dale, Gillian D. Beltz-Mohrmann, Arika A. Egan +13
New deep optical and near-infrared imaging is combined with archival ultraviolet and infrared data for fifteen nearby galaxies mapped in the Spitzer Extended Disk Galaxy Exploratio…
