Short-duration gamma-ray bursts from off-axis collapsars
Davide Lazzati, Brian J. Morsony, Mitchell C. Begelman
We present 2D high-resolution hydrodynamic simulations of the relativistic outflows of long-duration gamma-ray burst progenitors. We analyze the properties of the outflows at wide…
Prospects of High-Resolution X-ray Spectroscopy for AGN Feedback in Galaxy Clusters
S. Heinz, M. Brueggen, B. Morsony
One of the legacies of the {\rm Chandra} era is the discovery of AGN-inflated X-ray cavities in virtually all cool-core clusters, with mechanical luminosities comparable to or larg…
Very high efficiency photospheric emission in long duration gamma-ray bursts
Davide Lazzati, Brian J. Morsony, Mitch Begelman
We numerically analyze the evolution of a long-duration gamma-ray burst jet as it leaves the progenitor star and propagates to the photospheric radius, where radiation can be relea…
