Tracking the precession of compact binaries from their gravitational-wave signal
Patricia Schmidt, Mark Hannam, Sascha Husa +1
We present a simple method to track the precession of a black-hole-binary system, using only information from the gravitational-wave (GW) signal. Our method consists of locating th…
A search for gravitational waves associated with the August 2006 timing glitch of the Vela pulsar
The LIGO Scientific Collaboration, J. Abadie, B. P. Abbott +499
The physical mechanisms responsible for pulsar timing glitches are thought to excite quasi-normal mode oscillations in their parent neutron star that couple to gravitational wave e…
Length requirements for numerical-relativity waveforms
Mark Hannam, Sascha Husa, Frank Ohme +1
One way to produce complete inspiral-merger-ringdown gravitational waveforms from black-hole-binary systems is to connect post-Newtonian (PN) and numerical-relativity (NR) results…
First search for gravitational waves from the youngest known neutron star
LIGO Scientific Collaboration, J. Abadie, B. P. Abbott +537
We present a search for periodic gravitational waves from the neutron star in the supernova remnant Cassiopeia A. The search coherently analyzes data in a 12-day interval taken fro…
Matching post-Newtonian and numerical relativity waveforms: systematic errors and a new phenomenological model for non-precessing black hole binaries
L. Santamaria, F. Ohme, P. Ajith +10
We present a new phenomenological gravitational waveform model for the inspiral and coalescence of non-precessing spinning black hole binaries. Our approach is based on a frequency…
Constraining the mass of the graviton using coalescing black-hole binaries
Drew Keppel, P. Ajith
We study how well the mass of the graviton can be constrained from gravitational-wave (GW) observations of coalescing binary black holes. Whereas the previous investigations employ…
