Strongly Magnetized Accretion with Low Angular Momentum Produces a Weak Jet
Published 2025-01-01“…We find that when the Bondi radius exceeds a certain value relative to the black hole’s gravitational radius, this turbulence restricts the subsequent inflow of magnetic flux, strongly suppressing the strength of the jet. …”

On Disk Formation around Isolated Black Holes via Stream Accretion
Published 2025-01-01“…We investigate accretion onto an isolated black hole from uniform winds. If the winds are directed toward the black hole, then the accretion process can be well described by the classical Bondi–Hoyle–Lyttleton or BHL accretion. …”

Physical Pathways for JWST-observed Supermassive Black Holes in the Early Universe
Published 2025-01-01“…One model to create these massive objects is through direct collapse black holes (DCBHs) that provide massive seeds (∼10 ^5 –10 ^6 M _⊙ ), able to reach high masses in the limited time available. …”

Hubble Space Telescope Observations within the Sphere of Influence of the Powerful Supermassive Black Hole in PKS 0745-191
Published 2025-01-01“…We present Space Telescope Imaging Spectrograph observations from the Hubble Space Telescope of the supermassive black hole (SMBH) at the center of PKS 0745-191, a brightest cluster galaxy (BCG) undergoing powerful radio-mode active galactic nucleus (AGN) feedback ( P _cav ~ 5 × 10 ^45 erg s ^−1 ). …”
