Pearson cross-correlation in the first four black hole binary mergers

1 code implementation28 Aug 2020 Paolo Marcoccia, Felicia Fredriksson, Alex B. Nielsen, Germano Nardini

We adopt the Pearson cross-correlation measure to analyze the LIGO Hanford and LIGO Livingston detector data streams around the events GW150914, GW151012, GW151226 and GW170104.

Potential Gravitational-wave and Gamma-ray Multi-messenger Candidate from Oct. 30, 2015

1 code implementation25 Feb 2019 Alexander H. Nitz, Alex B. Nielsen, Collin D. Capano

By comparing the rate of binary neutron star mergers to our search-estimated rate of false alarms, we estimate that there is a 1 in 4 chance this candidate is astrophysical in origin.

Investigating the noise residuals around the gravitational wave event GW150914

3 code implementations9 Nov 2018 Alex B. Nielsen, Alexander H. Nitz, Collin D. Capano, Duncan A. Brown

We find that after subtracting the maximum likelihood waveform there are no statistically significant correlations between the residuals of the two detectors at the time of GW150914.

1-OGC: The first open gravitational-wave catalog of binary mergers from analysis of public Advanced LIGO data

1 code implementation5 Nov 2018 Alexander H. Nitz, Collin Capano, Alex B. Nielsen, Steven Reyes, Rebecca White, Duncan A. Brown, Badri Krishnan

The three most significant signals in our catalog correspond to the binary black hole mergers GW150914, GW151226, and LVT151012.
