A Multi-Code Analysis Toolkit for Astrophysical Simulation Data
Matthew J. Turk, Britton D. Smith, Jeffrey S. Oishi +4
The analysis of complex multiphysics astrophysical simulations presents a unique and rapidly growing set of challenges: reproducibility, parallelization, and vast increases in data…
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…
The Nature of the Warm/Hot Intergalactic Medium I. Numerical Methods, Convergence, and OVI Absorption
Britton D. Smith, Eric J. Hallman, J. Michael Shull +1
We perform a series of cosmological simulations using Enzo, an Eulerian adaptive-mesh refinement, N-body + hydrodynamical code, applied to study the warm/hot intergalactic medium.…
Protostellar Feedback Processes and the Mass of the First Stars
Jonathan C. Tan, Britton D. Smith, Brian W. O'Shea
We review theoretical models of Population III.1 star formation, focusing on the protostellar feedback processes that are expected to terminate accretion and thus set the mass of t…
Hubble/COS Observations of the Quasar HE 2347-4342: Probing the Epoch of He II Patchy Reionization at Redshifts z = 2.4-2.9
Michael Shull, Kevin France, Charles Danforth +2
We report ultraviolet spectra of the high-redshift (z_em = 2.9) quasar, HE 2347-4342, taken by the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST). Spectra in…
Galaxy Cluster Radio Relics in Adaptive Mesh Refinement Cosmological Simulations: Relic Properties and Scaling Relationships
Samuel W. Skillman, Eric J. Hallman, Brian W. O'Shea +3
Cosmological shocks are a critical part of large-scale structure formation, and are responsible for heating the intracluster medium in galaxy clusters. In addition, they are also c…
