Internal shocks in relativistic jets with time–dependent sources
نویسندگان
چکیده
We present a ballistic description of the formation and propagation of the working surface of a relativistic jet. Using simple laws of conservation of mass and linear momentum at the working surface, we obtain a full description of the working surface flow parametrised by the initial velocity and mass injection. This allows us to compute analytically the energy release at any time in the working surface. We compare this model with a new numerical code used for the propagation of a relativistic fluid in one dimension. We finally use this code to test the limits of our study.

Particle Acceleration at Multiple Internal Relativistic Shocks 3
Relativistic shocks provide an efficient method for high-energy particle acceleration in many astrophysical sources. Multiple shock systems are even more effective and of importance, for example, in the internal shock model of gamma-ray bursts. We investigate the reacceleration of pre-existing energetic particles at such relativistic internal shocks by the first order Fermi process of pitch ang...
متن کاملThe effects of sub-shells in highly magnetized relativistic flows
Astrophysical sources of relativistic jets or outflows, such as gamma-ray bursts (GRBs), active galactic nuclei (AGN) or micro-quasars, often show strong time variability. Despite such impulsive behavior, most models of these sources assume a steady state for simplicity. Here I consider a time-dependent outflow that is initially highly magnetized and divided into many well-separated sub-shells,...

متن کاملInternal shock model for Microquasars
We present a model for the radio outbursts of microquasars based on the assumption of quasi-continuous jet ejection. The jets are ‘lit up’ by shock fronts traveling along the jets during outbursts. The shocks accelerate relativistic particles which emit the observed synchrotron radiation. The observed comparatively flat decay light curves combined with gradually steepening spectral slopes are e...
متن کاملDeflection of jets induced by jet – cloud interactions
A non–relativistic and relativistic model in which astrophysical jets are deflected on passing through an isothermal high density region is analysed. The criteria for the stability of jets due to the formation of internal shocks are discussed.
