Early supernova emission -- logarithmic corrections to the planar phase
Tamar Faran, Re'em Sari
When the shock wave generated in a supernova explosion breaks out of the stellar envelope, the first photons, typically in the X-ray to UV range, escape to the observer. Following…
Oblique Shock Breakout from a Uniform Density Medium
Itai Linial, Re'em Sari
The emergence of a shock from a medium with a free surface is an important process in various astrophysical phenomena. It generates the first light associated with explosions like…
A Reverse Shock in GRB 181201A
Tanmoy Laskar, Hendrik van Eerten, Patricia Schady +26
We present comprehensive multiwavelength radio to X-ray observations of GRB 181201A spanning from s to days after the burst, comprising the first joint AL…
Tidal disruption events, main-sequence extreme-mass ratio inspirals and binary star disruptions in galactic nuclei
Re'em Sari, Giacomo Fragione
The Galactic Center has been under intense scrutiny in the recent years thanks to the unprecedented missions aiming at measuring the gas and star dynamics near the supermassive bla…
Recombination Effects on Supernova Light Curves
Tamar Faran, Tomer Goldfriend, Ehud Nakar +1
The light curves of type-II supernovae (SNe) are believed to be highly affected by recombination of hydrogen that takes place in their envelopes. In this work, we analytically inve…
