Bayesian frequency estimation at the fundamental quantum limit

Kavli Affiliate: Lee McCuller | First 5 Authors: James W. Gardner, James W. Gardner, , , | Summary: Searching for a weak signal at an unknown frequency is a canonical task in experiments probing fundamental physics such as gravitational-wave observatories and ultra-light dark matter haloscopes. These state-of-the-art sensors are limited by quantum noise arising from […]

Multi-year Polarimetric Monitoring of Four CHIME-Discovered Repeating Fast Radio Bursts with FAST

Kavli Affiliate: Kejia Lee | First 5 Authors: , , , , | Summary: In this study, we report multi-year polarization measurements of four repeating FRBs initially discovered by CHIME: FRBs~20190117A, 20190208A, 20190303A, and 20190417A. We observed the four repeating FRBs with FAST, detecting a total of 66 bursts. Two bursts from FRB~20190417A exhibit a […]

Image Marker

Kavli Affiliate: Lindsey Bleem | First 5 Authors: Ryan Walker, Ryan Walker, , , | Summary: A wide range of scientific imaging datasets benefit from human inspection for purposes ranging from prosaic-such as fault identification and quality inspection-to profound, enabling the discovery of new phenomena. As such, these datasets come in a wide variety of […]

Universal lower bound on the axion decay constant from free streaming effects

Kavli Affiliate: Wayne Hu | First 5 Authors: Keisuke Harigaya, Wayne Hu, Rayne Liu, Huangyu Xiao, | Summary: We show that enhancement of the axion relic abundance compared to the standard misalignment contribution generically leads to the production of nonzero momentum axion modes, resulting in warm dark matter behavior and enhanced isocurvature perturbations. It leads […]

The TESS Grand Unified Hot Jupiter Survey. III. Thirty More Giant Planets

Kavli Affiliate: Alan M. Levine | First 5 Authors: Samuel W. Yee, Samuel W. Yee, , , | Summary: We present the discovery of 30 transiting giant planets that were initially detected using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. These new planets orbit relatively bright ($G leq 12.5$) FGK host stars with […]
