Black hole quasinormal modes in the era of LIGO

Understand

After a long wait, gravitational wave astronomy has finally begun.

• Binary black hole mergers are being detected by LIGO and Virgo, and theorists are starting to receive a wealth of data to be analized.
• At this point we can at long last begin to test alternative theories of gravity and different models of compact objects.
• One powerful tool to do this is the perturbative analysis of background spacetimes.
