Coming of Age in the Dark Sector: How Dark Matter Haloes grow their Gravitational Potential Wells
Frank C. van den Bosch, Fangzhou Jiang, Andrew Hearin +3
We present a detailed study of how dark matter haloes assemble their mass and grow their (central) potential well. We characterize these via their mass accretion histories (MAHs) a…
Probing Satellite Quenching With Galaxy Clustering
Robert T. Chamberlain, Neal Dalal, Andrew Hearin +1
Satellites within simulated massive clusters are significantly spatially correlated with each other, even when those satellites are not gravitationally bound to each other. This co…
Accounting for baryonic effects in cosmic shear tomography: Determining a minimal set of nuisance parameters using PCA
Tim Eifler, Elisabeth Krause, Scott Dodelson +3
Systematic uncertainties that have been subdominant in past large-scale structure (LSS) surveys are likely to exceed statistical uncertainties of current and future LSS data sets,…
Beyond Halo Mass: Galactic Conformity as a Smoking Gun of Central Galaxy Assembly Bias
Andrew P. Hearin, Douglas F. Watson, Frank C. van den Bosch
Quenched central galaxies tend to reside in a preferentially quenched large-scale environment, a phenomenon that has been dubbed galactic conformity. Remarkably, this tendency pers…
Predicting Galaxy Star Formation Rates via the Co-evolution of Galaxies and Halos
Douglas F. Watson, Andrew P. Hearin, Andreas A. Berlind +6
In this paper, we test the age matching hypothesis that the star formation rate (SFR) of a galaxy of fixed stellar mass is determined by its dark matter halo formation history, and…
