متن کاملFirst LIGO events: binary black holes mergings
Based on evolutionary scenarios for binary stellar evolution we study the merging rates of relativistic binary stars (NS+NS, NS+BH, BH+BH) under di erent assumptions of BH formation. We nd the BH+BH merging rate in the range one per 200,000 { 500,000 year in a Milky-Way type galaxy, while the NS+NS merging rate Rns is approximately 10 times as high, which means that the expected event rate even...
متن کاملSearch for black hole ringdown signals in LIGO S4 data
The final state of a compact binary coalescence is expected to be a perturbed black hole which will radiate away the perturbations as gravitational waves. At late times, the distorted black hole will be sufficiently similar to a Kerr black hole [1] that black hole perturbation theory can be used to model the waveforms [2]. These ringdown waveforms are a superposition of quasi-normal modes, the ...
متن کاملGW150914: First results from the search for binary black hole coalescence with Advanced LIGO
B. P. Abbott et al. (LIGO Scientific Collaboration and Virgo Collaboration) (Received 9 March 2016; published 7 June 2016) On September 14, 2015, at 09∶50:45 UTC the two detectors of the Laser Interferometer GravitationalWave Observatory (LIGO) simultaneously observed the binary black hole merger GW150914. We report the results of a matched-filter search using relativistic models of compact-obj...
متن کاملLIGO / VIRGO searches for gravitational radiation in hypernovae
A torus around a stellar mass Kerr black hole can emit about 10% of the spin-energy of the black hole in gravitational radiation, potentially associated with a gamma-ray burst. Wide tori may develop buckling modes by the Papaloizou-Pringle instability and gravitational radiation-reaction forces in the Burke-Thorne approximation. Gravitational wave experiments may discover these emissions in a f...
