We use only whitened time series of measured gravitational-wave strain as an input, and we train and test on simulated binary black hole signals in synthetic Gaussian noise representative of Advanced LIGO sensitivity. Matched filtering A matched filter is obtained by correlating a known signal or template, with an unknown time series to detect the presence of the template in the unknown signal. The recent Nobel-prize-winning detections of gravitational waves from merging black holes and the subsequent detection of the collision of two neutron stars in coincidence with electromagnetic observations have inaugurated a new era of multimessenger astrophysics.

However, the computational cost of such searches in low latency . Since the first detection of a Gravitational Wave (GW) in September 2015 at the Laser Interferometer Gravitational-Wave Observatory (LIGO), it was unclear if the Einstein's Theory (E=MC2) was true . We seek to achieve the holy grail of Bayesian inference for gravitational-wave astronomy: using deep-learning techniques to instantly produce the posterior p (θ|D) for the source parameters θ, given the detector data D. 1. However, to date, these methods have not yet been successfully applied to the analysis of long stretches of data . Gravitational-wave detection strategies are based on a signal analysis technique known as matched filtering. By . The fundamental assumption of matched filtering is that the strain s(t) measured by the interferometric detector is made up of two additive components, namely the instrument noise n(t) and the (astrophysical) signal h(t): s(t)=n(t)+h(t) (1) ; Tutors - Your username was sent to you when you first registered. adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement 80NSSC21M0056 We use only whitened time series of measured gravitational-wave strain as an input, and we train and test on simulated binary black hole signals .
