The Concentration Dependence of the Galaxy-Halo Connection: Modeling Assembly Bias with Abundance Matching
Benjamin V. Lehmann, Yao-Yuan Mao, Matthew R. Becker +2
Empirical methods for connecting galaxies to their dark matter halos have become essential for interpreting measurements of the spatial statistics of galaxies. In this work, we pre…
Disentangling redshift-space distortions and nonlinear bias using the 2D power spectrum
Elise Jennings, Risa H. Wechsler, Samuel W. Skillman +1
We present the nonlinear 2D galaxy power spectrum, , in redshift space, measured from the Dark Sky simulations, using galaxy catalogs constructed with both halo occupation…
Dark Sky Simulations: Early Data Release
Samuel W. Skillman, Michael S. Warren, Matthew J. Turk +3
The Dark Sky Simulations are an ongoing series of cosmological N-body simulations designed to provide a quantitative and accessible model of the evolution of the large-scale Univer…
X-ray Observations of Complex Temperature Structure in the Cool-core cluster Abell 85
David Schenck, Abhirup Datta, Jack Burns +1
X-ray observations were used to examine the complex temperature structure of Abell 85, a cool-core galaxy cluster. Temperature features can provide evidence of merging events which…
Cosmological Simulations of Isotropic Conduction in Galaxy Clusters
Britton D. Smith, Brian W. O'Shea, G. Mark Voit +2
Simulations of galaxy clusters have a difficult time reproducing the radial gas-property gradients and red central galaxies observed to exist in the cores of galaxy clusters. Therm…
Cosmological MHD Simulations of Galaxy Cluster Radio Relics: Insights and Warnings for Observations
Samuel W. Skillman, Hao Xu, Eric J. Hallman +5
Non-thermal radio emission from cosmic ray electrons in the vicinity of merging galaxy clusters is an important tracer of cluster merger activity, and is the result of complex phys…
