Accelerated growth of seed black holes by dust in the early universe

KwangHo Park, Gen Chiaki, John H. Wise

We explore the effect of dust on the growth of seed black holes (BHs) in the early universe. Previous 1D radiation-hydrodynamic (RHD) simulations show that increased radiation pres…

Biconical-dominated Accretion Flow onto Seed Black Holes in a Hyper-accretion Regime

KwangHo Park, John H. Wise, Tamara Bogdanović +1

Hyperaccretion occurs when the gas inflow rate onto a black hole (BH) is so high that the radiative feedback cannot reverse the accretion flow. This extreme process is a promising…

The Interplay of Kinetic and Radiative Feedback in Galaxy Clusters

Yu Qiu, Tamara Bogdanovic, Yuan Li +2

Recent observations provide evidence that some cool-core clusters (CCCs) host quasars in their brightest cluster galaxies (BCGs). Motivated by these findings we use 3D radiation-hy…

Dusty Gas Accretion onto Massive Black Holes and Infrared Diagnosis of the Eddington Ratio

Hidenobu Yajima, Massimo Ricotti, KwangHo Park +1

Evidence for dust around supermassive black holes (SMBHs) in the early Universe is strongly suggested by recent observations. However, the accretion mechanism of SMBHs in dusty gas…

Radiation-driven turbulent accretion onto massive black holes

KwangHo Park, John H. Wise, Tamara Bogdanović

Accretion of gas and interaction of matter and radiation are at the heart of many questions pertaining to black hole (BH) growth and coevolution of massive BHs and their host galax…

Gaseous Dynamical Friction in Presence of Black Hole Radiative Feedback

KwangHo Park, Tamara Bogdanović

Dynamical friction is thought to be a principal mechanism responsible for orbital evolution of massive black holes (MBHs) in the aftermath of galactic mergers and an important chan…
