It is common knowledge that nothing in the universe can escape a Black Hole. But are there places in the universe from which a Black Hole cannot escape?
An archival X-ray search reveals that supermassive black holes at the center of galaxies may be surrounded by stellar-mass black hole companions.
Looking for something you cannot see, for example black holes, are tricky. The bending of light provides a solution.
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.
The authors discuss the possibility that the strangely-shaped supernova remnant W49B was created by a core-collapse supernova that formed strong bipolar jets instead of a spherical shockwave.
