Cosmography using strongly lensed gravitational waves from binary black holes
Souvik Jana, Shasvath J. Kapadia, Tejaswi Venumadhav +1
Third generation gravitational wave (GW) detectors are expected to detect millions of binary black hole (BBH) mergers during their operation period. A small fraction of them ($\sim…
Beyond the linear tide: impact of the non-linear tidal response of neutron stars on gravitational waveforms from binary inspirals
Hang Yu, Nevin N. Weinberg, Phil Arras +2
Tidal interactions in coalescing binary neutron stars modify the dynamics of the inspiral and hence imprint a signature on their gravitational wave (GW) signals in the form of an e…
Factorized Parameter Estimation for Real-Time Gravitational Wave Inference
Tousif Islam, Javier Roulet, Tejaswi Venumadhav
We present a parameter estimation framework for gravitational wave (GW) signals that brings together several ideas to accelerate the inference process. First, we use the relative b…
Removing degeneracy and multimodality in gravitational wave source parameters
Javier Roulet, Seth Olsen, Jonathan Mushkin +4
Quasicircular binary black hole mergers are described by 15 parameters, of which gravitational wave observations can typically constrain only independent combinations to…
New binary black hole mergers in the LIGO--Virgo O3a data
Seth Olsen, Tejaswi Venumadhav, Jonathan Mushkin +3
We report the detection of ten new binary black hole (BBH) mergers in the publicly released data from the the first half of the third observing run (O3a) of advanced LIGO and advan…
