Observing gravitational-wave transient GW150914 with minimal assumptions

  title={Observing gravitational-wave transient GW150914 with minimal assumptions},
  author={The Ligo Scientific Collaboration and The Virgo Collaboration},
The gravitational-wave signal GW150914 was first identified on Sept 14 2015 by searches for short-duration gravitational-wave transients. These searches identify time-correlated transients in multiple detectors with minimal assumptions aboutthe signal morphology, allowing them to be sensitive to gravitational waves emitted by a wide range of sources including binary black-hole mergers. Over the observational period from September 12th to October 20th 2015, these transient searches were… 
GWTC-2: Compact Binary Coalescences Observed by LIGO and Virgo during the First Half of the Third Observing Run
We report on gravitational-wave discoveries from compact binary coalescences detected by Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between 1 April 2019 15฀00
Rapid-response and high-precision wide-field photometry of transients and gravitational wave counterparts
This work focuses on the use of the small-aperture PIRATE robotic telescope, built with off the shelf components at a relatively low cost, in the observation of numerous astrophysical objects. This
Characterisation of the mechanical properties of thin-film mirror coating materials for use in future interferometric gravitational wave detectors
Predicted by Einstein’s General Theory of Relativity, gravitational waves are periodic fluctuations in the curvature of space-time that propagate at the speed of light and are caused by acceleration
Detecting and characterizing gravitational waves with minimal assumptions
After many years of preparation and anticipation, we are finally in the era of routine gravitational-wave detection. All of the detected signals so far have come from merging compact objects– either
Enhancing the significance of gravitational wave bursts through signal classification
This case study applies a multivariate analyses based on artificial neural networks to classify waves emitted in compact binary coalescences and enhances by orders of magnitude the significance of signals belonging to this broad astrophysical class against the noise background.
All-sky search for short gravitational-wave bursts in the first Advanced LIGO run
We present the results from an all-sky search for short-duration gravitational waves in the data of the first run of the Advanced LIGO detectors between September 2015 and January 2016. The search
Looking for ancillary signals around GW150914
We replicated the procedure in Liu and Jackson (arXiv:1609.08346), who had found evidence for a low amplitude signal in the vicinity of GW150914. This was based upon the large correlation between the

Characterization of transient noise in Advanced LIGO relevant to gravitational wave signal GW150914
On September 14, 2015, a gravitational wave signal from a coalescing black hole binary system was observed by the Advanced LIGO detectors. This paper describes the transient noise backgrounds used to
