Radio jets from stellar tidal disruptions [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2011 A star that passes too close to a massive black hole will be torn apart by tidal forces. The flare of photons emitted during the accretion of the stellar debris is predicted to be observable and candidates of such events have been observed at optical to ...

Quasi-periodic oscillations of GHz-band polarization in a black hole [PDF]
Nature CommunicationsRelativistic jets from accreting black holes radiate non-thermal emission which is highly variable in different time scales. Previous studies on black holes of different mass scales, including supermassive and stellar-mass black holes, only report flux ...

Two-component jet simulations: II. Combining analytical disk and stellar MHD outflow solutions [PDF]
, 2009 Theoretical arguments along with observational data of YSO jets suggest the presence of two steady components: a disk wind type outflow needed to explain the observed high mass loss rates and a stellar wind type outflow probably accounting for the ...

Shooting for the Stars: Jet-mode Feedback and AGN Jet Deceleration from Stellar Mass Loading
The Astrophysical JournalActive Galactic Nucleus (AGN) jets are thought to be vital ingredients in galaxy evolution through the action of kinetic feedback; however, how narrow, relativistic outflows couple to galaxies remains an open question.

Density Profiles of Collapsed Rotating Massive Stars Favor Long Gamma-Ray Bursts
The Astrophysical Journal Letters, 2023 Long-duration gamma-ray bursts (lGRBs) originate in relativistic collimated outflows—jets—that drill their way out of collapsing massive stars. Accurately modeling this process requires realistic stellar profiles for the jets to propagate through and ...

Collapsar Black Holes Are Likely Born Slowly Spinning
The Astrophysical Journal Letters, 2023 Collapsing stars constitute the main black hole (BH) formation channel, and are occasionally associated with the launch of relativistic jets that power γ -ray bursts (GRBs). Thus, collapsars offer an opportunity to infer the natal (before spin-up/down by

Power-law Distribution of Solar Cycle–modulated Coronal Jets
The Astrophysical Journal Supplement Series, 2023 Power-law distributions have been studied as a significant characteristic of nonlinear dissipative systems. Since discovering the power-law distribution of solar flares that was later extended to nanoflares and stellar flares, it has been widely accepted

A Global Inventory of Feedback
Galaxies, 2023 Feedback from both supermassive black holes and massive stars plays a fundamental role in the evolution of galaxies and the inter-galactic medium. In this paper, we use available data to estimate the total amount of kinetic energy and momentum created ...

AGN Jet Mass Loading and Truncation by Stellar Winds [PDF]
, 2006 Active Galactic Nuclei can produce extremely powerful jets. While tightly collimated, the scale of these jets and the stellar density at galactic centers implies that there will be many jet/star interactions, which can mass-load the jet through stellar ...

Supernova Hosts for Gamma-Ray Burst Jets: Dynamical Constraints [PDF]
, 2002 I constrain a possible supernova origin for gamma-ray bursts by modeling the dynamical interaction between a relativistic jet and a stellar envelope surrounding it.
