The Gamma-ray Burst Jet Energy Distribution Suggests A Quasi-universal, Weakly Magnetized Jet Evolving Over Cosmic Time

Nicole M. Lloyd-Ronning, Fabio De Colle, Gal Birenbaum +2

We present distributions of gamma-ray burst observed and inferred properties for those GRBs with redshifts. We show that the isotropic energy distribution, which spans over four or…

The GRB Intrinsic Duration Distribution: Progenitor Insights Across Cosmic Time

Nicole M. Lloyd-Ronning, Omer Bromberg, Tsvi Piran

We present the distribution of the intrinsic duration of gamma-ray bursts' prompt emission. This expands upon the analysis of Bromberg et al., 2012 and Bromberg et al. 2013 who sho…

Tidal disruption of a magnetized star

Pavel Abolmasov, Omer Bromberg, Amir Levinson +1

Tidal disruptions of stars by supermassive black holes in galactic centers (TDEs) are now being actively studied both theoretically and observationally. They are observed throughou…

Numerical approach to compressible shallow-water dynamics of neutron-star spreading layers

Aleksandr Rusakov, Pavel Abolmasov, Omer Bromberg

A weakly magnetized neutron star (NS) undergoing disk accretion should release about a half of its power in a compact region known as the accretion boundary layer. Latitudinal spre…

Afterglow Linear Polarization Signatures from Shallow GRB Jets: Implications for Energetic GRBs

Gal Birenbaum, Ramandeep Gill, Omer Bromberg +2

Gamma-ray bursts (GRBs) are powered by ultra-relativistic jets. The launching sites of these jets are surrounded by dense media, which the jets must cross before they can accelerat…
