GW190521 may be an intermediate mass ratio inspiral

2 code implementations23 Oct 2020 Alexander H. Nitz, Collin D. Capano

For the uniform in mass-ratio prior, we find that the component masses are $m_1^{\mathrm{src}} = 168_{-61}^{+15}\,\mathrm{M}_{\odot}$ and $m_2^{\mathrm{src}} = 16_{-3}^{+33}\,\mathrm{M}_{\odot}$.

Binary black hole spectroscopy: a no-hair test of GW190814 and GW190412

1 code implementation5 Aug 2020 Collin D. Capano, Alexander H. Nitz

Using these events, we search for physics beyond GR by allowing the source parameters measured from the sub-dominant harmonics to deviate from that of the dominant mode.

2-OGC: Open Gravitational-wave Catalog of binary mergers from analysis of public Advanced LIGO and Virgo data

1 code implementation11 Oct 2019 Alexander H. Nitz, Thomas Dent, Gareth S. Davies, Sumit Kumar, Collin D. Capano, Ian Harry, Simone Mazzon, Laura Nuttall, Andrew Lundgren, Marton Tápai

We identify a population of 14 binary black hole mergers with $p_{\mathrm{astro}} > 0. 5$ along with the GW170817 binary neutron star merger.

GW170817: Stringent constraints on neutron-star radii from multimessenger observations and nuclear theory

1 code implementation27 Aug 2019 Collin D. Capano, Ingo Tews, Stephanie M. Brown, Ben Margalit, Soumi De, Sumit Kumar, Duncan A. Brown, Badri Krishnan, Sanjay Reddy

The properties of neutron stars are determined by the nature of the matter that they contain.

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.

Posterior samples of the parameters of black hole mergers released to date in the second Advanced LIGO--Virgo observing run

1 code implementation22 Nov 2018 Soumi De, Collin D. Capano, Christopher M. Biwer, Alexander H. Nitz, Duncan A. Brown

This paper presents the first public data release of samples from the posterior probability density function for the three binary black hole mergers---GW170104, GW170608, and GW170814---detected during the second observing run of the Advanced LIGO and Virgo observatories.

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.

PyCBC Inference: A Python-based parameter estimation toolkit for compact binary coalescence signals

4 code implementations26 Jul 2018 C. M. Biwer, Collin D. Capano, Soumi De, Miriam Cabero, Duncan A. Brown, Alexander H. Nitz, V. Raymond

We introduce new modules in the open-source PyCBC gravitational- wave astronomy toolkit that implement Bayesian inference for compact-object binary mergers.
