“…We build on these efforts and use the constraints on GR deviations obtained by the LIGO-Virgo collaboration (LVC) [30] to analyze whether these two theories can be constrained with the binary BH events detected during the first two observation runs of the LVC. More specifically, we will consider the binary BH events in the LIGO-Virgo Catalog GWTC-1 GW150914 [31,32], GW151226 [33], GW170104 [34], GW170608 [35] and GW170814 [36] for which the posteriors on theory-independent GR modifications, obtained through a Markov-Chain-Monte-Carlo (MCMC) exploration of the parameter space, have been made public [3,37].

Gravitational waves can probe general relativity in the extreme gravity regime. We study how the events detected so far by the LIGO-Virgo collaboration can probe higher-curvature corrections to general relativity, focusing on Einstein-dilaton-Gauss-Bonnet and dynamical Chern-Simons gravity. We find that the two events with a low-mass m ≈ 7M ⊙ BH (GW151226 and GW170608) place stringent constraints on Einstein-dilaton-Gauss-Bonnet gravity, α 1/2 EdGB 5.6 km, whereas dynamical Chern-Simons gravity remains unconstrained.

“…As in the previous LIGO/Virgo searches [23][24][25], intervals of poor data quality are identified and excluded from the analysis. To monitor environmental disturbances and their influence on the detectors, each observatory is equipped with an array of sensors: seismometers, accelerometers, microphones, magnetometers, radio receivers, weather sensors, ac-power line monitors, and a cosmic-ray detector.…”

6We 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 algorithms use minimal assumptions on the signal morphology, so they are sensitive to a wide range of sources emitting gravitational waves. The analyses target transient signals with duration ranging from milliseconds to seconds over the frequency band of 32 to 4096 Hz. The first observed gravitational-wave event, GW150914, has been detected with high confidence in this search; the other known gravitational-wave event, GW151226, falls below the search's sensitivity. Besides GW150914, all of the search results are consistent with the expected rate of accidental noise coincidences. Finally, we estimate rate-density limits for a broad range of non-BBH transient gravitational-wave sources as a function of their gravitational radiation emission energy and their characteristic frequency. These rate-density upper-limits are stricter than those previously published by an order-of-magnitude.

“…As in previous LIGO, Virgo and GEO transient searches [17][18][19], a range of monitors tracking environmental noise and the state of the instruments are used to discard periods of poor quality data. Numerous studies have been performed to identify efficient veto criteria to remove nonGaussian noise features, while having the smallest possible impact on detector live time [27].…”

“…This leaves a background residual that has to be estimated from the data. To calculate the background rate of noise events arising from glitches occurring simultaneously at the two LIGO sites by chance [17][18][19], the analyses are repeated on Oð10 6 Þ independent timeshifted data sets. Those data sets are generated by translating the time of data in one interferometer by a delay of some integer number of seconds, much larger than the maximum GW travel time ≃10 ms between the Livingston and Hanford facilities.…”

“…Since burst methods do not require precise waveform models, the unmodeled search space may include BBH mergers with misaligned spins, large mass ratios, or eccentric orbits. A number of all-sky, all-time burst searches have been performed on data from initial LIGO and Virgo [17][18][19]. Recent work has focussed on improving detection confidence in unmodeled searches, and the last year has seen several improvements in the ability to distinguish astrophysical signals from noise transients [20][21][22][23][24].…”

The gravitational-wave signal GW150914 was first identified on September 14, 2015, by searches for short-duration gravitational-wave transients. These searches identify time-correlated transients in multiple detectors with minimal assumptions about the 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 12 to October 20, 2015, these transient searches were sensitive to binary black hole mergers similar to GW150914 to an average distance of ∼600 Mpc. In this paper, we describe the analyses that first detected GW150914 as well as the parameter estimation and waveform reconstruction techniques that initially identified GW150914 as the merger of two black holes. We find that the reconstructed waveform is consistent with the signal from a binary black hole merger with a chirp mass of ∼30 M ⊙ and a total mass before merger of ∼70 M ⊙ in the detector frame.
