This month’s undergraduate research post features a student who examined V404 Cygni, an X-ray binary that underwent a period of outburst. Read on to find out more!
Now that gravitational waves have been directly detected, we can begin to use binary black hole mergers to probe strange consequences of strong-field general relativity. Today’s post examines the prospect of detecting an effect called gravitational-wave memory, and considers its potential for helping you get in shape for summer.

The recent LIGO announcement has lead to exciting waves of new science. Today, we look at one theory about the potential gamma-ray burst associated with a gravitational wave.
Some fast radio bursts might be the result of a black hole lighting up a neutron star.
Quasar PSO J334.2028+01.4075 has a very healthy heart rate of 6.7 beats per decade, or once every 542 days. One explanation is that this guy hosts a pair of supermassive black holes. If true, then the astonishing interpretation of this quasar’s heart rate is that its black holes are only a few orbits away from merging!
