Tests of Gravitational-Wave Birefringence with the Open Gravitational-Wave Catalog

Kavli Affiliate: Lijing Shao | First 5 Authors: Yi-Fan Wang, Stephanie M. Brown, Lijing Shao, Wen Zhao, | Summary: The routine detection of gravitational-wave events from compact binary coalescences has allowed precise tests of gravity in strong field, dynamical field, and high energy regime. In this work, we report the results of testing gravitational-wave birefringence […]

Assisted Learning for Organizations with Limited Data

Kavli Affiliate: Yi Zhou | First 5 Authors: Cheng Chen, Jiaying Zhou, Jie Ding, Yi Zhou, | Summary: We develop an assisted learning framework for assisting organization-level learners to improve their learning performance with limited and imbalanced data. In particular, learners at the organization level usually have sufficient computation resource, but are subject to stringent […]

Dark matter constraints with stacked gamma rays scales with the number of galaxies

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, Oscar Macias, | Summary: Low-surface-brightness galaxies (LSBGs) are interesting targets for searches of dark matter emission due to their low baryonic content. However, predicting their expected dark matter emissivities is difficult because of observational challenges in their distance measurements. Here […]
