Relativistic Jets Shine through Shocks or Magnetic Reconnection [PDF]
, 2015 Observations of gamma-ray-bursts and jets from active galactic nuclei reveal that the jet flow is characterized by a high radiative e ffi ciency and that the dissipative mechanism must be a powerful accelerator of non-thermal particles.

Transverse stability of relativistic two-component jets [PDF]
, 2007 Context: Astrophysical jets from various sources seem to be stratified, with a fast inner jet and a slower outer jet. As it is likely that the launching mechanism for each component is different, their interface will develop differential rotation, while the outer jet radius represents a second interface where disruptions may occur. Aims: We explore the

A Novel Jet Model: Magnetically Collimated, Radiation-Pressure Driven Jet
, 2010 Relativistic jets from compact objects are ubiquitous phenomena in the Unvierse, but their driving mechanism has been an enigmatic issue over many decades.

Formation of precessing jets by tilted black hole discs in 3D general relativistic MHD simulations [PDF]
, 2017 Gas falling into a black hole (BH) from large distances is unaware of BH spin direction, and misalignment between the accretion disc and BH spin is expected to be common. However, the physics of tilted discs (e.g.

Financial Accountability &Management, EarlyView.ABSTRACT Social accounting practices attribute value to an organization's activities beyond traditional economic conceptions of success. In assessing the merit of such practices, we argue that it is helpful to extend our analytical focus beyond questions of what is evaluated and who evaluates to how valuations are performed.

RECOLLIMATION SHOCKS IN MAGNETIZED RELATIVISTIC JETS [PDF]
, 2015 We have performed two-dimensional special-relativistic magnetohydrodynamic simulations of non-equilibrium over-pressured relativistic jets in cylindrical geometry.

Full jet in quark-gluon plasma with hydrodynamic medium response [PDF]
Phys. Rev. C 95, 044909 (2017), 2017 We study the nuclear modifications of full jets and their structures in relativistic heavy-ion collisions including the effect of hydrodynamic medium response to jet quenching. To study the evolutions of the full jet shower and the traversed medium with energy and momentum exchanges between them, we formulate a coupled jet-fluid model consisting of a ...

Characterization of Jets in Relativistic Heavy Ion Collisions
, 2003 Jet quenching is considered to be one of the signatures of the formation of quark gluon plasma. In order to investigate the jet quenching, it is necessary to detect jets produced in relativistic heavy ion collisions, determine their properties and ...

High-energy neutrinos from reverse shocks in choked and successful relativistic jets [PDF]
, 2008 Highly relativistic jets are a key element of current gamma-ray burst models, where the jet kinetic energy is converted to radiation energy at optically thin shocks. High-energy neutrinos are also expected, from interactions of protons accelerated in the

EVOLUTION OF GLOBAL RELATIVISTIC JETS: COLLIMATIONS AND EXPANSION WITH kKHI AND THE WEIBEL INSTABILITY [PDF]
, 2015 In the study of relativistic jets one of the key open questions is their interaction with the environment. Here we study the initial evolution of both electron–proton ( e – − p + ?> ) and electron–positron (e±) relativistic jets, focusing on their ...
