A Differentiable Model of the Evolution of Dark Matter Halo Concentration
Dash Stevanovich, Andrew P. Hearin, Daisuke Nagai
We introduce a new model of the evolution of the concentration of dark matter halos, c(t). For individual halos, our model approximates c(t) as a power law with a time-dependent in…
Cluster Cosmology Without Cluster Finding
Enia Xhakaj, Alexie Leauthaud, Johannes Lange +5
We propose that observations of super-massive galaxies contain cosmological constraining power similar to conventional cluster cosmology, and we provide promising indications that…
Constraints on from a full-scale and full-shape analysis of redshift-space clustering and galaxy-galaxy lensing in BOSS
Johannes U. Lange, Andrew P. Hearin, Alexie Leauthaud +5
We present a novel simulation-based cosmological analysis of galaxy-galaxy lensing and galaxy redshift-space clustering. Compared to analysis methods based on perturbation theory,…
Assembly Bias & Redshift-Space Distortions: Impact on cluster dynamics tests of general relativity
Andrew P. Hearin
The redshift-space distortion (RSD) of galaxies surrounding massive clusters is emerging as a promising testbed for theories of modified gravity. Conventional applications of this…
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…
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…
