Jets, accretion and spin in supermassive black holes

Y Chen, Q Gu, J Yang, J Fan, X Yu… - … in Astronomy and …, 2024 - iopscience.iop.org
The theoretical model suggests that relativistic jets of active galactic nuclei (AGNs) rely on
the black hole spin and/or accretion. We study the relationship between jet, accretion, and …

[HTML][HTML] A Study of the Accretion–Jet Coupling of Black Hole Objects at Different Scales

Z Yang, QC Long, WJ Yang, AJ Dong - Universe, 2024 - mdpi.com
The fundamental plane of black hole activity is a very important tool to study accretion and
jets. However, we found that the SEDs of AGNs and XRBs are different in the 2–10 keV …

VLBI Detection of a Potential Active Radio Source Driving 100-kpc Scale Emission in the Ultraluminous Infrared Galaxy IRAS\,010042237

TJ Hayashi, Y Hagiwara, M Imanishi - arXiv preprint arXiv:2401.08009, 2024 - arxiv.org
Galaxy mergers induce the accretion of gas and dust toward the central region of the galaxy,
leading to subsequent activities of star formation and active galactic nuclei (AGNs). These …

Revisiting a Core–Jet Laboratory at High Redshift: Analysis of the Radio Jet in the Quasar PKS 2215+020 at z = 3.572
