Astronomers have known for a while that GRBs are sign-posts to galaxies which are forming lots of stars. But today’s paper used radio observations of the gas to connect that star formation to a recent merger.
In today’s paper, Rezzolla and Kumar present a solution to the x-ray afterglow problem for the short gamma ray burst model. They show that x-rays can glow steadily for hours after the initial gamma ray emission due to the interactions of a slow and a fast wind.
Asteroids and volcanoes are familiar harbingers of global doom. But what about Gamma Ray Bursts? Is another doomsday lurking?
Some GRB-SNe pairs show interesting correlations across their light curves.
This month’s undergraduate research post features pulsars as a probe of our galaxy’s magnetic field, and the possibility of asymmetries in supernovae associated with gamma-ray bursts.
Gamma-ray bursts are the most energetic explosions in the Universe. Today, we discuss how to use one GRB as a beacon to study the properties of a high redshift galaxy, the composition of the gas in the intergalactic medium at high redshift and the formation of dust in the Universe.
