Neutron Star Kicks from Asymmetric Collapse
Chris L. Fryer
Many neutron stars are observed to be moving with spatial velocities, in excess of 500km/s. A number of mechanisms have been proposed to give neutron stars these high velocities. O…
3-Dimensional Core-Collapse
C. L. Fryer, M. S. Warren
In this paper, we present the results of 3-dimensional collapse simulations of rotating stars for a range of stellar progenitors. We find that for the fastest spinning stars, rotat…
Diffuse X-Rays from the Inner 3 Parsecs of the Galaxy
Gabriel Rockefeller, Chris L. Fryer, Fulvio Melia +1
Recent observations with the Chandra X-ray Observatory have provided us with the capability to discriminate point sources, such as the supermassive black hole Sgr A*, from the diff…
Neutrino-Driven Explosions in GRBs and Hypernovae
Chris L. Fryer, Peter Meszaros
We study the physics behind the neutrino-driven mechanism for gamma-ray bursts and hypernovae, deriving the critical density at which these outbursts occur in the collapsar model.…
Gamma-Ray Lines from Asymmetric Supernovae
A. L. Hungerford, C. L. Fryer, M. S. Warren
We present 3-dimensional SPH simulations of supernova explosions from 100 seconds to 1 year after core-bounce. By extending our modelling efforts to a 3-dimensional hydrodynamics t…
