In today’s paper: how does tidal dissipation and gravitational wave emission affect the result of encounters between stars and black hole binaries in stellar clusters?
The quest for the true nature of gravity continues! Can gravitational waves help us find the right answer? Today’s paper describes how this could work.
In today’s paper, the authors test the theory that the earliest, metal-poorest stars are the primary source of binary black hole mergers.
Black holes colliding and neutron stars merging are not the only ways to create GWs! Dergachev and Papa, the authors of today’s paper, searched through the first half of the third LIGO observing run (called “O3a”) for continuous wave signals. They searched every point on the sky and recorded the deepest SNR they were able to search for a CW signal, leaving behind a treasure map (or atlas) for future studies
Thanks to gravitational waves, we have detections of black holes mergers. Now imagine they are embedded in AGN disks, can you guess what’s going to happen to them? The authors of today’s paper can tell you if your guess was correct!
We haven’t yet detected microhertz gravitational waves. This unusual detector could change that.
