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…
Detecting Gravitational Waves in Data with Non-Gaussian Noise
Barak Zackay, Tejaswi Venumadhav, Javier Roulet +2
Searches for gravitational waves crucially depend on exact signal processing of noisy strain data from gravitational wave detectors, which are known to exhibit significant non-Gaus…
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…
Template Bank for Compact Binary Coalescence Searches in Gravitational Wave Data: A General Geometric Placement Algorithm
Javier Roulet, Liang Dai, Tejaswi Venumadhav +2
We introduce an algorithm for placing template waveforms for the search of compact binary mergers in gravitational wave interferometer data. We exploit the smooth dependence of the…
A New Search Pipeline for Compact Binary Mergers: Results for Binary Black Holes in the First Observing Run of Advanced LIGO
Tejaswi Venumadhav, Barak Zackay, Javier Roulet +2
In this paper, we report on the construction of a new and independent pipeline for analyzing the public data from the first observing run of advanced LIGO for mergers of compact bi…
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…
Gravitational-wave-moderated Accretion: The Case of ES Ceti
Matthew S. B. Coleman, Tejaswi Venumadhav, Barak Zackay
We show that recent observations of the compact binary, AM CVn type system, ES Ceti are fully consistent with theoretical predictions of stable mass transfer moderated by angular m…
Highly Magnified Stars in Lensing Clusters: New Evidence in a Galaxy Lensed by MACS J0416.1-2403
Alexander A. Kaurov, Liang Dai, Tejaswi Venumadhav +2
We examine a caustic-straddling arc at in the field of the galaxy cluster MACS J0416.1-2403 () using archival multiband HST images and show that its surface bri…
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…
