A binary tree approach to template placement for searches for gravitational waves from compact binary mergers Open
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 based on a binary tree decomposition of the template bank para…

Metric Assisted Stochastic Sampling (MASS) search for gravitational waves from binary black hole mergers Open
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 fixed bank of template waveforms. This technique is competiti…

Template bank for spinning compact binary mergers in the second observation run of Advanced LIGO and the first observation run of Advanced Virgo Open
We describe the methods used to construct the aligned-spin template bank of gravitational waveforms used by the Gstreamer and Ligo Algorithm Library (GstLAL)-based pipeline to analyze data from the second observing run of Advanced Laser In…
Fast evaluation of multidetector consistency for real-time gravitational wave searches Open
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 search over possible signal parameters is performed. It is…
The GstLAL Search Analysis Methods for Compact Binary Mergers in Advanced LIGO's Second and Advanced Virgo's First Observing Runs Open
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 run (November 30, 2016 - August 26, 2017). The Advanced Vi…
The GstLAL template bank for spinning compact binary mergers in the second observation run of Advanced LIGO and Virgo Open
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 observing run of Advanced LIGO and Virgo. The bank expands upon …

Analysis framework for the prompt discovery of compact binary mergers in gravitational-wave data Open
We describe a stream-based analysis pipeline to detect gravitational waves\nfrom the merger of binary neutron stars, binary black holes, and\nneutron-star-black-hole binaries within ~ 1 minute of the arrival of the merger\nsignal at Earth.…
Searching for gravitational waves from compact binaries with precessing spins Open
Current searches for gravitational waves from compact-object binaries with\nthe LIGO and Virgo observatories employ waveform models with spins aligned (or\nanti-aligned) with the orbital angular momentum. Here, we derive a new\nstatistic t…
Implementing a search for gravitational waves from binary black holes with nonprecessing spin Open
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 template bank --- chosen to cover the full signal space of in…
Searching for Gravitational Waves from Compact Binaries with Precessing Spins Open
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 orbital angular momentum. Here, we derive a new statistic to s…
