Cosmic birefringence tomography with polarized Sunyaev Zel’dovich effect

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Ippei Obata, , , | Summary: We consider the polarized Sunyaev-Zel’dovich (pSZ) effect for a tomographic probe of cosmic birefringence, including all relevant terms of the pSZ effect in the cosmic microwave background (CMB) observables, some of which were ignored in the previous works. The […]

Radial and Non-Radial Oscillations of Inverted Hybrid Stars

Kavli Affiliate: Lijing Shao | First 5 Authors: Chen Zhang, Yudong Luo, Hong-bo Li, Lijing Shao, Renxin Xu | Summary: We study the radial and non-radial oscillations of Cross stars (CrSs), i.e., stars with a quark matter crust and a hadronic matter core in an inverted order compared to conventional hybrid stars. We draw comparisons […]

A Mini-Neptune Orbiting the Metal-poor K Dwarf BD+29 2654

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Fei Dai, Kevin C. Schlaufman, Henrique Reggiani, Luke Bouma, Andrew W. Howard | Summary: We report the discovery and Doppler mass measurement of a 7.4-day 2.3-$R_oplus$ mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIRES spectrum, the Gaia parallax, and multi-wavelength […]

Dark matter search with a strongly-coupled hybrid spin system

Kavli Affiliate: Jia Liu | First 5 Authors: Kai Wei, Zitong Xu, Yuxuan He, Xiaolin Ma, Xing Heng | Summary: Observational evidence suggests the existence of dark matter (DM), which comprises approximately $84.4%$ of matter in the universe. Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of DM. Our experiment […]

Universal Asymptotics for High Energy CFT Data

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Nathan Benjamin, Jaeha Lee, Hirosi Ooguri, David Simmons-Duffin, | Summary: Equilibrium finite temperature observables of a CFT can be described by a local effective action for background fields — a "thermal effective action." This effective action determines the asymptotic density of states of a CFT as a […]
