Will the LIGO collaboration announce today that it has detected more gravitational waves? There is a session this morning at 10.45 a.m. at the APS April Meeting with the enticing name “Results from Advanced LIGO“, and I think it’s safe to say that you should get there early if you want to get a seat.
In February the LIGO announced the first ever detection of a gravitational wave, which was made while the collaboration’s two detectors were being calibrated. Now that the experiment has been running since September 2015, it will be interesting to see if the first detection was a rare event that they were lucky to see, or if LIGO will be detecting the mergers of black-hole pairs on a regular basis.
Stay tuned to for updates, and in the meantime enjoy this photograph I took of the Mormon Temple, which is across the road from the convention centre here in Salt Lake City.
