Metric Assisted Stochastic Sampling (MASS) search for gravitational waves from binary black hole mergers

Understand

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 competitive with standard template-bank-driven pipelines in both computational cost and sensitivity.
• However, the complexity of the analysis is simpler allowing for easy configuration and horizontal scaling across heterogeneous grids of computers.
• To demonstrate the method we analyze approximately one month of public LIGO data from July 27 00:00 2017 UTC - Aug 25 22:00 2017 UTC and recover eight known confident gravitational wave candidates.
