Black Hole Ringing, Quasinormal Modes, and Light Rings | Gaurav Khanna

1 Sep 2016 | Abstract: | Modelling of gravitational waves from binary black hole inspiral has played
an important role in the recent observations of such signals. The late-stage
ringdown phase of the gravitational waveform is often associated with the null
particle orbit (light ring") of the black hole spacetime. With simple models
we show that this link between the light ring and spacetime ringing is based
more on the history of applications than on an actual constraining
relationship. We also show, in particular, that a better understanding of the
disassociation between the two, may be relevant to the astrophysically
interesting case of rotating (Kerr) black holes. | Source: | arXiv, 1609.0083 | Services: | Forum | Review | PDF | Favorites |
