Narrow spectra of repeating fast radio bursts: A magnetospheric origin

Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Yuan-Pei Yang, Hong-Bo Li, Jifeng Liu, Renxin Xu | Summary: Fast radio bursts (FRBs) can present a variety of polarization properties, and some of them have narrow spectra. We study spectral properties from perspectives of intrinsic radiation mechanisms and absorption during the waves propagating in […]

KMT-2023-BLG-1431Lb: A New $q < 10^{-4}$ Microlensing Planet from a Subtle Signature

Kavli Affiliate: Subo Dong | First 5 Authors: Aislyn Bell, Jiyuan Zhang, Youn Kil Jung, Jennifer C. Yee, Hongjing Yang | Summary: The current studies of microlensing planets are limited by small number statistics. Follow-up observations of high-magnification microlensing events can efficiently form a statistical planetary sample. Since 2020, the Korea Microlensing Telescope Network (KMTNet) […]

Quantum Gravity Effects on Fermionic Dark Matter and Gravitational Waves

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Stephen F. King, Rishav Roshan, Xin Wang, Graham White, Masahito Yamazaki | Summary: We explore the phenomenological consequences of breaking discrete global symmetries in quantum gravity (QG). We extend a previous scenario where discrete global symmetries are responsible for scalar dark matter (DM) and domain walls (DWs), […]

Gravitomagnetic Clock Effect: Using GALILEO to explore General Relativity

Kavli Affiliate: Sven Herrmann | First 5 Authors: Jan Scheumann, Dennis Philipp, Sven Herrmann, Eva Hackmann, Benny Rievers | Summary: All experiments to date are in remarkable agreement with the predictions of Einstein’s theory of gravity, General Relativity. Besides the classical tests, involving light deflection, orbit precession, signal delay, and the gravitational redshift, modern technology […]

New limits on the local Lorentz invariance violation of gravity in the Standard-Model Extension with pulsars

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiming Dong, Ziming Wang, Lijing Shao, , | Summary: Lorentz Invariance Violation (LIV) is posited as a possible relic effect of quantum gravity at low energy scales. The Standard-Model Extension provides an effective field-theoretic framework for examining possible deviations attributed to LIV. With the observations of the […]
