Optical follow-up of gravitational wave triggers with DECam during the first two LIGO/VIRGO observing runs
K. Herner, J. Annis, D. Brout +82
Gravitational wave (GW) events detectable by LIGO and Virgo have several possible progenitors, including black hole mergers, neutron star mergers, black hole--neutron star mergers,…
Narrow-band search of continuous gravitational-wave signals from Crab and Vela pulsars in Virgo VSR4 data
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +894
In this paper we present the results of a coherent narrow-band search for continuous gravitational-wave signals from the Crab and Vela pulsars conducted on Virgo VSR4 data. In orde…
Efficient Estimation of Highly Structured Posteriors of Gravitational-Wave Signals with Markov-Chain Monte Carlo
Benjamin Farr, Vicky Kalogera, Erik Luijten
We introduce a new Markov-Chain Monte Carlo (MCMC) approach designed for efficient sampling of highly correlated and multimodal posteriors. Parallel tempering, though effective, is…
Inadequacies of the Fisher Information Matrix in gravitational-wave parameter estimation
Carl L. Rodriguez, Benjamin Farr, Will M. Farr +1
The Fisher Information Matrix (FIM) has been the standard approximation to the accuracy of parameter estimation on gravitational-wave signals from merging compact binaries due to i…
Fortifying the characterization of binary mergers in LIGO data
Tyson B. Littenberg, Michael Coughlin, Benjamin Farr +1
The study of compact binary in-spirals and mergers with gravitational wave observatories amounts to optimizing a theoretical description of the data to best reproduce the true dete…
