Impact of half-wave plate systematics on the measurement of cosmic birefringence from CMB polarization

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Marta Monelli, Eiichiro Komatsu, Alexandre E. Adler, Matteo Billi, Paolo Campeti | Summary: Polarization of the cosmic microwave background (CMB) can probe new parity-violating physics such as cosmic birefringence (CB), which requires exquisite control over instrumental systematics. The non-idealities of the half-wave plate (HWP) represent a source […]

A giant glitch from the magnetar SGR J1935+2154 before FRB 200428

Kavli Affiliate: Kejia Lee | First 5 Authors: Mingyu Ge, Yuan-Pei Yang, Fangjun Lu, Shiqi Zhou, Long Ji | Summary: Fast radio bursts (FRBs) are short pulses observed in radio frequencies usually originating from cosmological distances. The discovery of FRB 200428 and its X-ray counterpart from the Galactic magnetar SGR J1935+2154 suggests that at least […]

Mirror Dark Sector Solution of the Hubble Tension with Time-varying Fine-structure Constant

Kavli Affiliate: Joshua Frieman | First 5 Authors: John Zhang, Joshua Frieman, , , | Summary: We explore a model introduced by Cyr-Racine, Ge, and Knox (arXiv:2107.13000(2)) that resolves the Hubble tension by invoking a “mirror world" dark sector with energy density a fixed fraction of the “ordinary" sector of Lambda-CDM. Although it reconciles cosmic […]
