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…
