The GstLAL Search Analysis Methods for Compact Binary Mergers in Advanced LIGO's Second and Advanced Virgo's First Observing Runs
Surabhi Sachdev, Sarah Caudill, Heather Fong +26
After their successful first observing run (September 12, 2015 - January 12, 2016), the Advanced LIGO detectors were upgraded to increase their sensitivity for the second observing…
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…
Toward Early-Warning Detection of Gravitational Waves from Compact Binary Coalescence
Kipp Cannon, Romain Cariou, Adrian Chapman +11
Rapid detection of compact binary coalescence (CBC) with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt de…
Improving the sensitivity of a search for coalescing binary black holes with non-precessing spins in gravitational wave data
Stephen Privitera, Satyanarayan R. P. Mohapatra, Parameswaran Ajith +6
We demonstrate the implementation of a sensitive search pipeline for gravitational waves from coalescing binary black holes whose components have spins aligned with the orbital ang…
Braid Groups of the Sun Graph
Alice Neels, Stephen Privitera
In this article we calculate the n-string braid groups of certain non-contractible graphs. We use techniques from the work of A. Abrams, F. Connolly and M. Doig combined with Van K…
Template bank for spinning compact binary mergers in the second observation run of Advanced LIGO and the first observation run of Advanced Virgo
Debnandini Mukherjee, Sarah Caudill, Ryan Magee +25
We describe the methods used to construct the aligned-spin template bank of gravitational waveforms used by the GstLAL-based inspiral pipeline to analyze data from the second obser…
Fast evaluation of multi-detector consistency for real-time gravitational wave searches
Chad Hanna, Sarah Caudill, Cody Messick +17
Gravitational waves searches for compact binary mergers with LIGO and Virgo are presently a two stage process. First, a gravitational wave signal is identified. Then, an exhaustive…
Searching for Gravitational Waves from Compact Binaries with Precessing Spins
Ian Harry, Stephen Privitera, Alejandro Bohé +1
Current searches for gravitational waves from compact-object binaries with the LIGO and Virgo observatories employ waveform models with spins aligned (or anti-aligned) with the orb…
A binary tree approach to template placement for searches for gravitational waves from compact binary mergers
Chad Hanna, James Kennington, Shio Sakon +30
We demonstrate a new geometric method for fast template placement for searches for gravitational waves from the inspiral, merger and ringdown of compact binaries. The method is bas…
Implementing a search for gravitational waves from non-precessing, spinning binary black holes
Collin Capano, Ian Harry, Stephen Privitera +1
Searching for gravitational waves (GWs) from binary black holes (BBHs) with LIGO and Virgo involves matched-filtering data against a set of representative signal waveforms --- a te…
Analysis Framework for the Prompt Discovery of Compact Binary Mergers in Gravitational-wave Data
Cody Messick, Kent Blackburn, Patrick Brady +24
We describe a stream-based analysis pipeline to detect gravitational waves from the merger of binary neutron stars, binary black holes, and neutron-star-black-hole binaries within…
Metric Assisted Stochastic Sampling (MASS) search for gravitational waves from binary black hole mergers
Chad Hanna, Prathamesh Joshi, Rachael Huxford +29
We present a novel gravitational wave detection algorithm that conducts a matched filter search stochastically across the compact binary parameter space rather than relying on a fi…
