A Dynamical Test for Cooling-Induced Entrainment in a Runaway Supermassive Black Hole Tail
Ish Kaul, S. Peng Oh
Radiative turbulent mixing layers are widely invoked to explain the survival, growth, and entrainment of cold gas in hot astrophysical flows, but quantitative dynamical tests have…
JWST Confirmation of a Runaway Supermassive Black Hole via its Supersonic Bow Shock
Pieter van Dokkum, Connor Jennings, Imad Pasha +6
We present JWST/NIRSpec IFU observations of a candidate runaway supermassive black hole at the tip of a 62 kpc-long linear feature at z=0.96. The JWST data show a sharp kinematic d…
: Self-Sustained Streaming Motions in Multi-Phase MHD
Chaoran Wang, S. Peng Oh, Yan-Fei Jiang +1
Radiative cooling can drive dynamics in multi-phase gas. A dramatic example is hydrodynamic `shattering', the violent, pressure-driven fragmentation of a cooling cloud which falls…
Magnetosonic Waves as a Driver of Observed Temperature Fluctuation Patterns in AGN Accretion Disks
Ish Kaul, Omer Blaes, Yan-Fei Jiang +1
Recent observations have revealed slow, coherent temperature fluctuations in AGN disks that propagate both inward and outward at velocities of , a kind of variabi…
Radiation and Magnetic Pressure Support in Accretion Disks around Supermassive Black Holes and The Physical Origin of the Extreme Ultraviolet to Soft X-ray Spectrum
Yan-Fei Jiang, Omer Blaes, Ish Kaul +1
We present the results of four three-dimensional radiation magnetohydrodynamic simulations of accretion disks around a solar mass black hole, which produce the far ultraviol…
Tales of Tension: Magnetized Infalling Clouds and Cold Streams in the CGM
Ish Kaul, Brent Tan, S. Peng Oh +1
The observed star formation and wind outflow rates in galaxies suggest cold gas must be continually replenished via infalling clouds or streams. Previous studies have highlighted t…
