On the Deceleration and Spreading of Relativistic Jets I: Jet Dynamics
Paul C. Duffell, Tanmoy Laskar
Jet breaks in gamma ray burst (GRB) afterglows provide a direct probe of their collimation angle. Modeling a jet break requires an understanding of the "jet spreading" process, whe…
Modules for Experiments in Stellar Astrophysics (MESA): Convective Boundaries, Element Diffusion, and Massive Star Explosions
Bill Paxton, Josiah Schwab, Evan B. Bauer +10
We update the capabilities of the software instrument Modules for Experiments in Stellar Astrophysics (MESA) and enhance its ease of use and availability. Our new approach to locat…
A GRB and Broad-lined Type Ic Supernova from a Single Central Engine
Jennifer Barnes, Paul C. Duffell, Yuqian Liu +4
Unusually high velocities (< ~0.1c) and correspondingly high kinetic energies have been observed in a subset of Type Ic supernovae (so-called "broad-lined Ic" supernovae; SNe Ic-BL…
