Stellar Signatures of AGN Jet Triggered Star Formation [PDF]

open access: yesThe Astrophysical Journal, 2014
To investigate feedback between relativistic jets emanating from Active Galactic Nuclei (AGN) and the stellar population of the host galaxy, we analyze the long-term evolution of the galaxy-scale simulations by Gaibler et al.

Quasi-periodic oscillations of GHz-band polarization in a black hole [PDF]

open access: yesNature Communications
Relativistic 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 ...

Magnetic Fields in Stellar Jets [PDF]

open access: yesThe Astrophysical Journal, 2007
Although several lines of evidence suggest that jets from young stars are driven magnetically from accretion disks, existing observations of field strengths in the bow shocks of these flows imply that magnetic fields play only a minor role in the ...

Radio jets from stellar tidal disruptions [PDF]

open access: yesMonthly 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 ...

Unifying the Zoo of Jet-Driven Stellar Explosions [PDF]

open access: yesThe Astrophysical Journal, 2012
We present a set of numerical simulations of stellar explosions induced by relativistic jets emanating from a central engine sitting at the center of compact, dying stars. We explore a wide range of durations of the central engine activity, two candidate

Density Profiles of Collapsed Rotating Massive Stars Favor Long Gamma-Ray Bursts

open access: yesThe 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 ...

Steady stellar jets [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1987
This paper contains some results of axisymmetric numerical calculations of the shock structures in steady supersonic jets in which there is significant radiative cooling. We find that the regularly spaced shock cells found in adiabatic jets still occur and that cooling can by itself induce shocks if it is fast enough.

Collapsar Black Holes Are Likely Born Slowly Spinning

open access: yesThe 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

open access: yesThe 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
