Black Hole Mergers in Nuclear Star Clusters
How frequent are black hole mergers in the centers of galaxies?
These aren’t the bursts you’re looking for
During the search for an elusive electromagnetic counterpart to the newest gravitational wave in town, GW170104, a very special supernova was uncovered. Here we discuss its classification and whether it is linked to the origin of GW170104 .
Things that go “chirp” in the night
Today’s paper talks about the not-yet-observed electromagnetic counterparts to gravitational waves
Hunting for ECOs: Gravitational Wave “Smoking Guns”
Echoes after the initial gravitational wave signal are the “smoking gun” signature of exotic compact objects (ECOs).
Counterparts to Gravitational Wave Events: Very Important Needles in a Very Large Haystack
Detecting electromagnetic and gravitational signals from a single astrophysical event will be revolutionary, but how do we find the former when we don’t know exactly where the latter is?
Observing across the gravitational wave spectrum
If a low-frequency gravitational wave detector, like LISA, existed 5 years ago, we would have been able to predict that LIGO would detect a binary merger on September 14, 2015 at 09:50:45 plus or minus a few seconds.
