Boosting jittering jets by neutrino heating in core collapse supernovae [PDF]

, 2022
I estimate the energy that neutrino heating adds to the outflow that jets induce in the collapsing core material in core collapse supernovae (CCSNe), and find that this energy crudely doubles the energy that the jets deposit into the outer core. I consider the jittering jets explosion mechanism where there are several stochastic jet-launching episodes,

Multi-spacecraft Observations of the 2022 March 25 CME and EUV Wave: An Analysis of Their Propagation and Interrelation

The Astrophysical Journal, 2023
This paper reports on a well-defined EUV wave associated with a coronal mass ejection (CME) observed on 2022 March 25. The CME was observed by Solar Orbiter (SolO) during its first close perihelion (0.32 au) and by several other spacecraft from different

MODELING JET INTERACTIONS WITH THE AMBIENT MEDIUM

Acta Polytechnica, 2013
Recent high-resolution (see, e.g., [13]) observations of astrophysical jets reveal complex structures apparently caused by ejecta from the central engine as the ejecta interact with the surrounding interstellar material.

Knots in Relativistic Transverse Stratified Jets

Galaxies, 2017
We investigate the plasmoid knot formation in stratified relativistic jet by means of relativistic magneto-hydrodynamics simulations. Indeed, astrophysical jets in active galactic nuclei (AGN) seem to be transversely stratified, with a fast inner jet and

The baryon loading effect on relativistic astrophysical jet transport in the interstellar medium

New Journal of Physics, 2018
The composition of the astrophysical relativistic jets remains uncertain. By kinetic particle-in-cell simulations, we show that the baryon component in the jet, or the so-called baryon loading effect (BLE), heavily affects relativistic jets transport ...

The first science result with the JENSA gas-jet target: Confirmation and study of a strong subthreshold F18(p,α)O15 resonance

Physics Letters B, 2015
The astrophysical F18(p,α)O15 rate determines, in large part, the extent to which the observable radioisotope 18F is produced in novae. This rate, however, has been extremely uncertain owing to the unknown properties of a strong subthreshold resonance ...

Shocks and Photoionization of the Inner 650 au Jet of the Interacting Binary Star R Aquarii from Multiwavelength Hubble Space Telescope Observations

The Astrophysical Journal, 2023
Astrophysical jets are present in a range of environments, including young stellar objects, X-ray binaries, and active galactic nuclei, but their formation is still not fully understood.

Observation of poloidal magnetic flux emission from the post-pinch phase of a plasma focus and its significance for laboratory simulation of astrophysical jets

Fundamental Plasma Physics, 2023
Astrophysical jets are plasma flows, which are observed to substantially maintain their transverse size while travelling distances orders-of-magnitude larger.

Scaled laboratory experiments explain the kink behaviour of the Crab Nebula jet

Nature Communications, 2016
The periodical change of the Crab nebula’s jet direction challenges our understanding of astrophysical jet dynamics. Here the authors use high-power lasers to create a jet that can be directly compared to the Crab nebula’s, and report the detection of ...

Astrophysical Neutrinos and Blazars

Universe, 2021
We review and discuss recent results on the search for correlations between astrophysical neutrinos and γ-ray-detected sources, with many extragalactic studies reporting potential associations with different types of blazars.
