The velocity distribution of outflows driven by choked jets in stellar envelopes [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Many stripped envelope supernovae (SNe) present a signature of high-velocity material responsible for broad absorption lines in the observed spectrum.

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 ...

Oscillation of high-energy neutrinos from choked jets in stellar and merger ejecta [PDF]
, 2020 We present a comprehensive study on oscillation of high-energy neutrinos from two different environments: blue supergiant progenitors that may harbor low-power gamma-ray burst (GRB) jets and neutron star merger ejecta that would be associated with short ...

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

Inclined jets inside a common envelope of a triple stellar system [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We conduct a three-dimensional hydrodynamical simulation to study the interaction of two opposite inclined jets inside the envelope of a giant star, and find that the jets induce many vortexes inside the envelope and that they efficiently remove mass ...

RECOLLIMATION BOUNDARY LAYERS AS X-RAY SOURCES IN YOUNG STELLAR JETS [PDF]
, 2014 Young stars accrete mass from circumstellar disks and, in many cases, the accretion coincides with a phase of massive outflows, which can be highly collimated. Those jets emit predominantly in the optical and IR wavelength range.

Observable Signature of Merging Stellar-mass Black Holes in Active Galactic Nuclei [PDF]
Astrophysical Journal, 2023 The origin of stellar-mass black hole mergers discovered through gravitational waves is being widely debated. Mergers in the disks of active galactic nuclei (AGNs) represent a promising source of origin, with possible observational clues in the ...

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 ...
