Population statistics of nanohertz gravitational wave sources
Jiming Yu, Zhen Pan, Xiao Xue +1
The recent detection of a nanohertz gravitational wave (GW) background by pulsar timing arrays (PTA) has sparked extensive discussions regarding its origin-whether it arises from a…
Wave Mechanics, Interference, and Decoherence in Strong Gravitational Lensing
Calvin Leung, Dylan Jow, Prasenjit Saha +3
Wave-mechanical effects in gravitational lensing have long been predicted, and with the discovery of populations of compact transients such as gravitational wave events and fast ra…
Mapping the Likelihood of GW190521 with Diverse Mass and Spin Priors
Seth Olsen, Javier Roulet, Horng Sheng Chia +4
We map the likelihood of GW190521, the heaviest detected binary black hole (BBH) merger, by sampling under different mass and spin priors designed to be uninformative. We find that…
Distribution of Effective Spins and Masses of Binary Black Holes from the LIGO and Virgo O1-O3a Observing Runs
Javier Roulet, Horng Sheng Chia, Seth Olsen +4
The distribution of effective spin , a parameter that encodes the degree of spin-orbit alignment in a binary system, has been widely regarded as a robust discriminator…
Signs of Higher Multipoles and Orbital Precession in GW151226
Horng Sheng Chia, Seth Olsen, Javier Roulet +4
We present a reanalysis of GW151226, the second binary black hole merger discovered by the LIGO--Virgo Collaboration. Previous analysis showed that the best-fit waveform for this e…
Binary Black Hole Mergers from LIGO/Virgo O1 and O2: Population Inference Combining Confident and Marginal Events
Javier Roulet, Tejaswi Venumadhav, Barak Zackay +2
We perform a statistical inference of the astrophysical population of binary black hole (BBH) mergers observed during the first two observing runs of Advanced LIGO and Advanced Vir…
Search for Lensed Gravitational Waves Including Morse Phase Information: An Intriguing Candidate in O2
Liang Dai, Barak Zackay, Tejaswi Venumadhav +2
We search for strongly lensed and multiply imaged gravitational wave signals in the second observing run of Advanced LIGO and Advanced Virgo (O2). We exploit a new source of inform…
Detecting Gravitational Waves With Disparate Detector Responses: Two New Binary Black Hole Mergers
Barak Zackay, Liang Dai, Tejaswi Venumadhav +2
We introduce a new technique to search for gravitational wave events from compact binary mergers that produce a clear signal only in a single gravitational wave detector, and margi…
New binary black hole mergers in the second observing run of Advanced LIGO and Advanced Virgo
Tejaswi Venumadhav, Barak Zackay, Javier Roulet +2
We report the detection of new binary black hole merger events in the publicly available data from the second observing run of advanced LIGO and advanced Virgo (O2). The mergers we…
A Highly Spinning and Aligned Binary Black Hole Merger in the Advanced LIGO First Observing Run
Barak Zackay, Tejaswi Venumadhav, Liang Dai +2
We report a new binary black hole merger in the publicly available LIGO First Observing Run (O1) data release. The event has an inverse false alarm rate of one per six years in the…
Probing the Black Hole Merger History in Clusters using Stellar Tidal Disruptions
Johan Samsing, Tejaswi Venumadhav, Liang Dai +5
The dynamical assembly of binary black holes (BBHs) in dense star clusters (SCs) is one of the most promising pathways for producing observable gravitational wave (GW) sources, how…
Multimessenger Parameter Estimation of GW170817
David Radice, Liang Dai
We combine gravitational wave (GW) and electromagnetic (EM) data to perform a Bayesian parameter estimation of the binary neutron star (NS) merger GW170817. The EM likelihood is co…
Probing motion of fast radio burst sources by timing strongly lensed repeaters
Liang Dai, Wenbin Lu
Given the possible repetitive nature of fast radio bursts (FRBs), their cosmological origin, and their high occurrence, detection of strongly lensed sources due to intervening gala…
