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

open access: yesNew 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 ...

Relativistic Jets in Core-collapse Supernovae [PDF]

open access: yesThe Astrophysical Journal Letters, 2017
After decades of extensive research the mechanism driving core-collapse supernovae (CCSNe) is still unclear. One common mechanism is a neutrino-driven outflow, but others have been proposed.

Quasiperiodic Polarized Emissions from Kink Structure in Magnetized Relativistic Jets [PDF]

open access: greenThe Astrophysical Journal
Recent polarimetric observations of blazars indicate the development of current-driven (CD) kink instability after passing the recollimation shocks in the relativistic jets and association with quasiperiodic oscillations (QPOs).

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 ...

Studies of Relativistic Jets in Active Galactic Nuclei with SKA [PDF]

open access: yes, 2015
Relativistic jets in active galactic nuclei (AGN) are among the most powerful astrophysical objects discovered to date. Indeed, jetted AGN studies have been considered a prominent science case for SKA, and were included in several different chapters of ...

Some implications of inverse-Compton scattering of hot cocoon radiation by relativistic jets in gamma-ray bursts [PDF]

open access: bronze, 2014
Long Gamma-Ray Bursts (GRB) relativistic jets are surrounded by hot cocoons which confine jets during their punch out from the progenitor star. These cocoons are copious sources of X-ray photons that can be and are inverse-Compton (IC) scattered to MeV ...

Microscopic Processes in Global Relativistic Jets Containing Helical Magnetic Fields [PDF]

open access: yesGalaxies, 2016
In the study of relativistic jets one of the key open questions is their interaction with the environment on the microscopic level. Here, we study the initial evolution of both electron–proton ( e − – p + ) and electron–positron ( e ± )

Observational signatures of stellar explosions driven by relativistic jets [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
The role of relativistic jets in unbinding the stellar envelope during a supernova (SN) associated with a gamma-ray burst (GRB) is unclear. To study that, we explore observational signatures of stellar explosions that are driven by jets.

A Unified Theory of Jetted Tidal Disruption Events: From Promptly Escaping Relativistic to Delayed Transrelativistic Jets [PDF]

open access: yesAstrophysical Journal Letters, 2023
Only a tiny fraction ∼1% of stellar tidal disruption events (TDEs) generate powerful relativistic jets evidenced by luminous hard X-ray and radio emissions.
