Little Red Dots as the Very First Activity of Black Hole Growth

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, , , , | Summary: The James Webb Space Telescope has detected massive black holes (BHs) with masses of $sim 10^{6-8}~M_odot$ within the first billion years of the universe. One of the remarkable findings is the identification of "Little Red Dots" (LRDs), a unique class […]

Quasi-periodic oscillations of GHz-band polarization in a black hole

Kavli Affiliate: Luis C. Ho | First 5 Authors: Wei Wang, Jiashi Chen, Pengfu Tian, Luis C. Ho, Xiaohui Sun | Summary: Relativistic jets from accreting black holes (BHs) radiate non-thermal emission which is highly variable in different time scales. Magnetic fields anchored to a rotating BH or accretion disc accelerate and collimate jets of […]
