Kavli Affiliate: Robert M. Wald | First 5 Authors: Jose María Ezquiaga, Daniel E. Holz, Wayne Hu, Macarena Lagos, Robert M. Wald | Summary: Assessing the probability that two or more gravitational waves (GWs) are lensed images of the same source requires an understanding of the image properties, including their relative phase shifts in strong […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Martin A. Bourne, Debora Sijacki, , , | Summary: While there is overwhelming observational evidence of AGN-driven jets in galaxy clusters and groups, if and how the jet energy is delivered to the ambient medium remains unanswered. Here we perform very high resolution AGN jet simulations within […]
Kavli Affiliate: Edward Morgan | First 5 Authors: Fei Dai, Arpita Roy, Benjamin Fulton, Paul Robertson, Lea Hirsch | Summary: We report the measurement of a spectroscopic transit of TOI-1726 c, one of two planets transiting a G-type star with $V$ = 6.9 in the Ursa Major Moving Group ($sim$400 Myr). With a precise age […]
Kavli Affiliate: Joshua Frieman | First 5 Authors: Yu-Ching Chen, Xin Liu, Wei-Ting Liao, A. Miguel Holgado, Hengxiao Guo | Summary: Periodically variable quasars have been suggested as close binary supermassive black holes. We present a systematic search for periodic light curves in 625 spectroscopically confirmed quasars with a median redshift of 1.8 in a […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Wei-Ting Liao, Yu-Ching Chen, Xin Liu, A. Miguel Holgado, Hengxiao Guo | Summary: Binary supermassive black holes (BSBHs) are expected to be a generic byproduct from hierarchical galaxy formation. The final coalescence of BSBHs is thought to be the loudest gravitational wave (GW) siren, yet no confirmed […]
