Low significance of evidence for black hole echoes in gravitational wave data
Julian Westerweck, Alex B. Nielsen, Ofek Fischer-Birnholtz +6
Recent detections of merging black holes allow observational tests of the nature of these objects. In some proposed models, non-trivial structure at or near the black hole horizon…
Comments on: "Echoes from the abyss: Evidence for Planck-scale structure at black hole horizons"
Gregory Ashton, Ofek Birnholtz, Miriam Cabero +7
Recently, Abedi, Dykaar and Afshordi claimed evidence for a repeating damped echo signal following the binary black hole merger gravitational-wave events recorded in the first obse…
Searches for continuous gravitational waves from Scorpius X-1 and XTE J1751-305 in LIGO's sixth science run
Grant David Meadors, Evan Goetz, Keith Riles +2
Scorpius X-1 (Sco X-1) and X-ray transient (XTE) J1751-305 are Low-Mass X-ray Binaries (LMXBs) that may emit continuous gravitational waves detectable in the band of ground-based i…
Tuning into Scorpius X-1: adapting a continuous gravitational-wave search for a known binary system
Grant David Meadors, Evan Goetz, Keith Riles
We describe how the TwoSpect data analysis method for continuous gravitational waves (GWs) has been tuned for directed sources such as the Low Mass X-ray Binary (LMXB), Scorpius X-…
Gravitational waves from Sco X-1: A comparison of search methods and prospects for detection with advanced detectors
C. Messenger, H. J. Bulten, S. G. Crowder +13
The low-mass X-ray binary Scorpius X-1 (Sco X-1) is potentially the most luminous source of continuous gravitational-wave radiation for interferometers such as LIGO and Virgo. For…
Parameter estimation for compact binary coalescence signals with the first generation gravitational-wave detector network
the LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +801
Compact binary systems with neutron stars or black holes are one of the most promising sources for ground-based gravitational wave detectors. Gravitational radiation encodes rich i…
Einstein@Home all-sky search for periodic gravitational waves in LIGO S5 data
J. Aasi, J. Abadie, B. P. Abbott +794
This paper presents results of an all-sky searches for periodic gravitational waves in the frequency range [50, 1190] Hz and with frequency derivative ranges of [-2 x 10^-9, 1.1 x…
The characterization of Virgo data and its impact on gravitational-wave searches
J. Aasi, J. Abadie, B. P. Abbott +798
Between 2007 and 2010 Virgo collected data in coincidence with the LIGO and GEO gravitational-wave (GW) detectors. These data have been searched for GWs emitted by cataclysmic phen…
Search for Gravitational Waves from Low Mass Compact Binary Coalescence in LIGO's Sixth Science Run and Virgo's Science Runs 2 and 3
the LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +796
We report on a search for gravitational waves from coalescing compact binaries using LIGO and Virgo observations between July 7, 2009 and October 20, 2010. We searched for signals…
All-sky Search for Periodic Gravitational Waves in the Full S5 LIGO Data
J. Abadie, B. P. Abbott, R. Abbott +794
We report on an all-sky search for periodic gravitational waves in the frequency band 50-800 Hz and with the frequency time derivative in the range of 0 through -6e-9 Hz/s. Such a…
Search for gravitational waves from binary black hole inspiral, merger and ringdown
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +721
We present the first modeled search for gravitational waves using the complete binary black hole gravitational waveform from inspiral through the merger and ringdown for binaries w…
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…
