Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions
EPJ Web of Conferences, 2013 Before the launch of the Fermi satellite only two classes of AGNs were known to produce relativistic jets and thus emit up to the γ-ray energy range: blazars and radio galaxies, both hosted in giant elliptical galaxies.

Relativistic stellar jets: dynamics and non-thermal radiation
EPJ Web of Conferences, 2013 Relativistic stellar jets, produced in binary systems called microquasars, propagate through media with different spatial scales releasing their energy in the form of work and radiation from radio to gamma rays.

Relativistic Jets in Core-collapse Supernovae [PDF]
The Astrophysical Journal Letters, 2019 Abstract 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. Among those, a long-standing idea is that jets play an important role in supernova (SN) explosions. Gamma-ray bursts (GRBs) that accompany “

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 ...

Simulations of relativistic extragalactic jets [PDF]
The Astrophysical Journal, 1994 We describe a method for the numerical solution of the relativistic Euler equations which we have found to be both robust and efficient, and which has enabled us to simulate relativistic jets. The technique employs a solver of the Godunov-type, with approximate solution of the local Riemann problems, applied to laboratory frame variables.

Relativistic Jets from Collapsars [PDF]
The Astrophysical Journal, 2000 Using a collapsar progenitor model of MacFadyen & Woosley we have simulated the propagation of an axisymmetric jet through a collapsing rotating massive star with the GENESIS multi-dimensional relativistic hydrodynamic code. The jet forms as a consequence of an assumed (constant or variable) energy deposition in the range $10^{50}$ erg s$^{-1}$ to $
