The Impact of Cluster Structure and Dynamical State on Scatter in the Sunyaev-Zel'dovich Flux-Mass Relation
H. -Y. Karen Yang, Suman Bhattacharya, Paul M. Ricker
Cosmological constraints from cluster surveys rely on accurate mass estimates from the mass-observable relations. In order to avoid systematic biases and reduce uncertainties, we s…
The Impact of Type Ia Supernova Ejecta on Binary Companions
P. M. Ricker, K. -C. Pan, R. E. Taam
We present adaptive mesh refinement (AMR) hydrodynamical simulations of the interaction between Type Ia supernovae and their companion stars within the context of the single-degene…
Examining subgrid models of supermassive black holes in cosmological simulation
P. M. Sutter, P. M. Ricker
While supermassive black holes (SMBHs) play an important role in galaxy and cluster evolution, at present they can only be included in large-scale cosmological simulation via subgr…
Impact of Type Ia Supernova Ejecta on a Helium-star Binary Companion
Kuo-Chuan Pan, Paul M. Ricker, Ronald E. Taam
The impact of Type Ia supernova ejecta on a helium-star companion is investigated via high-resolution, two-dimensional hydrodynamic simulations. For a range of helium-star models a…
