Method to get Better Sky Maps in a GstLAL Low-Latency Analysis
Prathamesh Joshi, Becca Ewing, Chad Hanna +40
Modeled gravitational wave searches correlate the strain data with a bank of gravitational wave template waveforms to make detections of gravitational wave candidates, and these re…
Improved ranking statistics of the GstLAL inspiral search for compact binary coalescences
Leo Tsukada, Prathamesh Joshi, Shomik Adhicary +37
Starting from May 2023, the LIGO Scientific, Virgo and KAGRA Collaboration is planning to conduct the fourth observing run with improved detector sensitivities and an expanded dete…
Automating the Inclusion of Subthreshold Signal-to-Noise Ratios for Rapid Gravitational-Wave Localization
Cody Messick, Surabhi Sachdev, Kipp Cannon +29
The accurate localization of gravitational-wave (GW) events in low-latency is a crucial element in the search for further multimessenger signals from these cataclysmic events. The…
GstLAL: A software framework for gravitational wave discovery
Kipp Cannon, Sarah Caudill, Chiwai Chan +28
The GstLAL library, derived from Gstreamer and the LIGO Algorithm Library, supports a stream-based approach to gravitational-wave data processing. Although GstLAL was primarily des…
Improving the background estimation technique in the GstLAL inspiral pipeline with the time-reversed template bank
Chiwai Chan, Kipp Cannon, Sarah Caudill +20
Background estimation is important for determining the statistical significance of a gravitational-wave event. Currently, the background model is constructed numerically from the s…
iDQ: Statistical Inference of Non-Gaussian Noise with Auxiliary Degrees of Freedom in Gravitational-Wave Detectors
Reed Essick, Patrick Godwin, Chad Hanna +2
Gravitational-wave detectors are exquisitely sensitive instruments and routinely enable ground-breaking observations of novel astronomical phenomena. However, they also witness non…
Cyberinfrastructure Requirements to Enhance Multi-messenger Astrophysics
Philip Chang, Gabrielle Allen, Warren Anderson +39
The identification of the electromagnetic counterpart of the gravitational wave event, GW170817, and discovery of neutrinos and gamma-rays from TXS 0506+056 heralded the new era of…
Methods for the detection of gravitational waves from sub-solar mass ultracompact binaries
Ryan Magee, Anne-Sylvie Deutsch, Phoebe McClincy +6
We describe detection methods for extensions of gravitational wave searches to sub-solar mass compact binaries. Sub-solar mass searches were previously carried out using Initial LI…
Multi-Messenger Astrophysics: Harnessing the Data Revolution
Gabrielle Allen, Warren Anderson, Erik Blaufuss +27
The past year has witnessed discovery of the first identified counterparts to a gravitational wave transient (GW 170817A) and a very high-energy neutrino (IceCube-170922A). These s…
Systematic errors in estimation of gravitational-wave candidate significance
Collin Capano, Thomas Dent, Chad Hanna +4
The statistical significance of a candidate gravitational-wave (GW) event is crucial to the prospects for a confirmed detection, or for its selection as a candidate for follow-up e…
Likelihood-Ratio Ranking Statistic for Compact Binary Coalescence Candidates with Rate Estimation
Kipp Cannon, Chad Hanna, Jacob Peoples
We present a new likelihood-ratio ranking statistic for use in searches for gravitational waves from the inspiral and merger of compact object binaries. Expanding on previous work,…
