Optically Thick Outflow Driven by Supercritical Accretion May Explain Little Red Dots
Jun-Rong Liu, Hua Feng, Luis C. Ho
Recent JWST observations have revealed a population of compact, optically red sources known as Little Red Dots (LRDs). A popular interpretation is that LRDs host massive black hole…

Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: Contribution to AGN disk viscosity
Jun-Rong Liu, Jian-Min Wang, Hua Feng
It is widely believed that stellar-mass black holes (sMBHs) exist within the accretion disks of active galactic nuclei (AGN), forming a distinct population termed ``accretion-modif…
