Small black hole meets big black hole
What happens as a small black hole spirals into a supermassive black hole?
What happens as a small black hole spirals into a supermassive black hole?
Transient noise in the LIGO detector – called “glitches” – can contaminate gravitational wave signals. We need to know how to deal with them, particularly in the case when we don’t know what the signal will look like.
How do we identify whether gravitational waves are produced by triple systems?
Gravitational waves are believed to be able to “kick” black hole merger remnants out of their host galaxy. We can search for signatures of that kick directly in gravitational wave signals.
Continuous gravitational waves produced by spinning neutron stars are another avenue for LIGO to listen to the Universe.
