Particle Conversions Beyond the WKB Approximation and Solar-Induced Gravitational Waves from Dark Photon Dark Matter

Kavli Affiliate: Jia Liu | First 5 Authors: Tengyu Ai, Yuxuan He, Jia Liu, Xiaolin Ma, Xiao-Ping Wang | Summary: We investigate the conversion of kinetic mixing dark photon dark matter into gravitational waves within the magnetic field of the Sun. Our study reveals that the WKB approximation is invalid in this scenario. We derive […]

Little Red Dots: Rapidly Growing Black Holes Reddened by Extended Dusty Flows

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Zhengrong Li, Kohei Inayoshi, Kejian Chen, Kohei Ichikawa, Luis C. Ho | Summary: The James Webb Space Telescope (JWST) observations have revolutionized extragalactic research, particularly with the discovery of little red dots (LRD), which we propose are dust-reddened broad-line active galactic nuclei (AGNs). Their unique v-shape spectral […]
