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…
Statistical Microlensing Toward Magnified High-Redshift Star Clusters
Liang Dai
We study light variability of gravitationally magnified high-redshift star clusters induced by a foreground population of microlenses. This arises as the incoherent superposition o…
Source properties of the lowest signal-to-noise-ratio binary black hole detections
Yiwen Huang, Carl-Johan Haster, Salvatore Vitale +6
We perform a detailed parameter estimation study of binary black hole merger events reported in Zackay et al. and Venumadhav et al.. These are some of the faintest signals reported…
Asymmetric Surface Brightness Structure of Caustic Crossing Arc in SDSS J1226+2152: A Case for Dark Matter Substructure
Liang Dai, Alexander A. Kaurov, Keren Sharon +6
We study the highly magnified arc SGAS J122651.3+215220 caused by a star-forming galaxy at crossing the lensing caustic cast by the galaxy cluster SDSS J1226+2152 ($z_l=…
