Characterization of Transient Noise in Advanced LIGO Relevant to Gravitational Wave Signal GW150914
نویسندگان
چکیده
On 14 September 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 determine the significance of the event (designated GW150914) and presents the results of investigations into potential correlated or uncorrelated sources of transient noise in the detectors around the time of the event. The detectors were operating nominally at the time of GW150914. We have ruled out environmental influences and non-Gaussian instrument noise at either LIGO detector as the cause of the observed gravitational wave signal.

Detecting Gravitational-Wave Memory with LIGO: Implications of GW150914.
It may soon be possible for Advanced LIGO to detect hundreds of binary black hole mergers per year. We show how the accumulation of many such measurements will allow for the detection of gravitational-wave memory: a permanent displacement of spacetime that comes from strong-field, general relativistic effects. We estimate that Advanced LIGO operating at design sensitivity may be able to make a ...
متن کاملRadio Follow-up of Gravitational-wave Triggers during Advanced Ligo O1
We present radio follow-up observations carried out with the Karl G. Jansky Very Large Array during the first observing run (O1) of the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO). A total of three gravitational wave triggers were followed up during the ≈ 4 months of O1, from September 2015 to January 2016. Two of these triggers, GW150914 and GW151226, are binary black h...
متن کاملEvidence of gravitational waves, or evidence of confirmation bias?
On February 11 2016 the LIGO Scientific Collaboration announced the discovery of gravitational waves. Their announcement has been met with a great deal of excitement and enthusiasm by the scientific community. However, a careful and detailed analysis of the published papers, and other internal LIGO documents, reveal critical scientific methodology problems and unresolved questions surrounding t...
متن کاملRemarks on Graviton Propagation in Light of GW 150914
The observation of gravitational waves from the Laser Interferometer Gravitational-Wave Observatory (LIGO) event GW150914 may be used to constrain the possibility of Lorentz violation in graviton propagation, and the observation by the Fermi Gamma-Ray Burst Monitor of a transient source in apparent coincidence may be used to constrain the difference between the velocities of light and gravitati...
متن کاملClassification methods for noise transients in advanced gravitational-wave detectors II: performance tests on Advanced LIGO data
The data taken by the advanced LIGO and Virgo gravitational-wave detectors contains short duration noise transients that limit the significance of astrophysical detections and reduce the duty cycle of the instruments. As the advanced detectors are reaching sensitivity levels that allow for multiple detections of astrophysical gravitational-wave sources it is crucial to achieve a fast and accura...
