Multi-field dark energy: cosmic acceleration on a steep potential

Kavli Affiliate: Misao Sasaki | First 5 Authors: Yashar Akrami, Misao Sasaki, Adam R. Solomon, Valeri Vardanyan, | Summary: We argue that dark energy with multiple fields is theoretically well-motivated and predicts distinct observational signatures, in particular when cosmic acceleration takes place along a trajectory that is highly non-geodesic in field space. Such models provide […]

Phase effects from strong gravitational lensing of gravitational waves

Kavli Affiliate: Robert M. Wald | First 5 Authors: Jose MarĂ­a 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 […]

AGN jet feedback on a moving mesh: gentle cluster heating by weak shocks and lobe disruption

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 […]

Candidate Periodically Variable Quasars from the Dark Energy Survey and the Sloan Digital Sky Survey

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 […]

Discovery of a Candidate Binary Supermassive Black Hole in a Periodic Quasar from Circumbinary Accretion Variability

Kavli Affiliate: R. G. McMahon | 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 […]
