Constraints on Long-Ranged Interactions Between Dark Matter and the Standard Model

Kavli Affiliate: Peter Graham | First 5 Authors: Zachary Bogorad, Peter Graham, Harikrishnan Ramani, , | Summary: Dark matter’s existence is known thanks to its gravitational interaction with Standard Model particles, but it remains unknown whether this is the only force present between them. While many searches for such new interactions with dark matter focus […]

Investigating the sightline of a highly scattered FRB through a filamentary structure in the local Universe

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Kaitlyn Shin, Calvin Leung, Sunil Simha, Bridget C. Andersen, Emmanuel Fonseca | Summary: Fast radio bursts (FRBs) are unique probes of extragalactic ionized baryonic structure as each signal, through its burst properties, holds information about the ionized matter it encounters along its sightline. FRB 20200723B is […]

Tracking the jet-like corona of black hole Swift J1727.8-1613 during a flare state through Type-C quasi-periodic oscillations

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jie Liao, Ning Chang, Lang Cui, Pengfei Jiang, Didong Mou | Summary: Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients typically manifest in the low-hard and hard-intermediate states. This study presents a detailed spectral and temporal analysis of the black hole candidate Swift J1727.8-1613 using […]
