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 […]

The Convergence of Heavy and Light Seeds to Overmassive Black Holes at Cosmic Dawn

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Kohei Inayoshi, Zoltan Haiman, Luis C. Ho, Ken Ohsuga | Summary: The James Webb Space Telescope (JWST) has revealed low-luminosity active galactic nuclei (AGNs) at redshifts of $zgtrsim 4-7$, many of which host accreting massive black holes (BHs) with BH-to-galaxy mass ($M_{rm BH}/M_{star}$) ratios exceeding […]
