We report on Day 2 of the 2022 April APS Meeting!
Going with the Tide: Does tidal dissipation play an important role in stellar/black hole mergers?
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?
How to use gravitational waves to test if Einstein was right
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.
HEAVY, BUT NOT METAL: Could Metal-Free Stars be the Source of Massive Black Hole Mergers?
In today’s paper, the authors test the theory that the earliest, metal-poorest stars are the primary source of binary black hole mergers.
Using LIGO to Treasure Hunt
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
