No gravitational waves found by LIGO
The LIGO collaboration just announced that no periodic gravitational waves were found in some frequency bands. Such gravitational waves are expected to be generated by neutron stars. They looked for coincidences between the two interferometers at Livingston and Hanford. It seems that finding gravitational waves are becoming a sort of Mission: impossible.
