Probing the Curious Case of a Galaxy Cluster Merger in Abell 115 with High Fidelity Chandra X-ray Temperature and Radio Maps
Eric J. Hallman, Brian Alden, David Rapetti +2
We present results from an X-ray and radio study of the merging galaxy cluster Abell 115. We use the full set of 5 Chandra observations taken of A115 to date (360 ks total integrat…
Length Scales and Turbulent Properties of Magnetic Fields in Simulated Galaxy Clusters
Hilary Egan, Brian W. O'Shea, Eric Hallman +5
Additional physics beyond standard hydrodynamics is needed to fully model the intracluster medium (ICM); however, as we move to more sophisticated models, it is important to consid…
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…
On The Road To More Realistic Galaxy Cluster Simulations: The Effects of Radiative Cooling and Thermal Feedback Prescriptions on the Observational Properties of Simulated Galaxy Clusters
Stephen Skory, Eric Hallman, Jack O. Burns +3
Flux limited X-ray surveys of galaxy clusters show that clusters come in two roughly equally proportioned varieties: "cool core" clusters (CCs) and non-"cool core" clusters (NCCs).…
Structure and Turbulence in Simulated Galaxy Clusters and the Implications for the Formation of Radio Halos
Eric J. Hallman, Tesla E. Jeltema
We track the histories of massive clusters of galaxies formed within a cosmological hydrodynamic simulation. Specifically, we track the time evolution of the energy in random bulk…
The Properties of X-ray Cold Fronts in a Statistical Sample of Simulated Galaxy Clusters
Eric J. Hallman, Samuel W. Skillman, Tesla E. Jeltema +4
We examine the incidence of cold fronts in a large sample of galaxy clusters extracted from a (512h^-1 Mpc) hydrodynamic/N-body cosmological simulation with adiabatic gas physics c…
