Sign of hard X-ray pulsation from the gamma-ray binary system LS 5039

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hiroki Yoneda, Kazuo Makishima, Teruaki Enoto, Dmitry Khangulyan, Takahiro Matsumoto | Summary: To understand the nature of the brightest gamma-ray binary system LS 5039, hard X-ray data of the object, taken with the Suzaku and NuSTAR observatories in 2007 and 2016, respectively, were analyzed. The two data […]

2, 12, 117, 1959, 45171, 1170086, …: A Hilbert series for the QCD chiral Lagrangian

Kavli Affiliate: Tom Melia | First 5 Authors: Lukas Graf, Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama | Summary: We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extended to incorporate the external fields. The action of charge conjugation […]

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 […]

TKS III: A Stellar Obliquity Measurement of TOI-1726 c

Kavli Affiliate: Edward Morgan | 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 constraint from cluster membership, TOI-1726 provides a great opportunity to test various obliquity excitation scenarios […]

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: 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 […]
