GW190521 may be an intermediate mass ratio inspiral
Alexander H. Nitz, Collin D. Capano
GW190521 is the first confident observation of a binary black hole merger with total mass . Given the lack of observational constraints at these masses…
Gravitational-wave Merger Forecasting: Scenarios for the early detection and localization of compact-binary mergers with ground based observatories
Alexander H. Nitz, Marlin Schäfer, Tito Dal Canton
We present the prospects for the early (pre-merger) detection and localization of compact-binary coalescences using gravitational waves over the next 10 years. Early warning can en…
Realtime search for compact binary mergers in Advanced LIGO and Virgo's third observing run using PyCBC Live
Tito Dal Canton, Alexander H. Nitz, Bhooshan Gadre +5
The third observing run of Advanced LIGO and Advanced Virgo took place between April 2019 and March 2020 and resulted in dozens of gravitational-wave candidates, many of which are…
Search for gravitational waves from high-mass-ratio compact-binary mergers of stellar mass and sub-solar mass black holes
Alexander Harvey Nitz, Yi-Fan Wang
We present the first search for gravitational waves from the coalescence of stellar mass and sub-solar mass black holes with masses between and $0.01…
Detection of gravitational-wave signals from binary neutron star mergers using machine learning
Marlin B. Schäfer, Frank Ohme, Alexander H. Nitz
As two neutron stars merge, they emit gravitational waves that can potentially be detected by earth bound detectors. Matched-filtering based algorithms have traditionally been used…
Measuring the eccentricity of GW170817 and GW190425
Amber K. Lenon, Alexander H. Nitz, Duncan A. Brown
Two binary neutron star mergers, GW170817 and GW190425, have been detected by Advanced LIGO and Virgo. These signals were detected by matched-filter searches that assume the star's…
A Search for Gravitational Waves from Binary Mergers with a Single Observatory
Alexander H. Nitz, Thomas Dent, Gareth S. Davies +1
We present a search for merging compact binary gravitational-wave sources that produce a signal appearing solely or primarily in a single detector. Past analyses have heavily relie…
Extending the PyCBC search for gravitational waves from compact binary mergers to a global network
Gareth S. Davies, Thomas Dent, Márton Tápai +3
The worldwide advanced gravitational-wave (GW) detector network has so far primarily consisted of the two Advanced LIGO observatories at Hanford and Livingston, with Advanced Virgo…
