Spectra and power of relativistic jets
The power of blazar jets rivals the power that gravity can extract from accreting matter. The mechanism launching and accelerating jets can be considered as the most efficient engine operating in radio–loud sources. It is still a matter of debate if the jet carries this power to the radio lobes, hundreds of kpc away, in the form of Poynting flux or bulk kinetic energy, or both, and if these two...
متن کاملSpectra and power of blazar jets
The spectra of blazars form a sequence which can be parametrized in term of their observed bolometric luminosity. At the most powerful extreme of the sequence we find objects whose jet power can rival the power extracted by accretion, while at the low power end of the sequence we find TeV and TeV candidate blazars, whose spectral properties can give information on the particle acceleration mech...
متن کاملRelativistic large scale jets and minimum power requirements
The recent discovery, by the Chandra satellite, that jets of blazars are strong X–ray emitters at large scales (0.1–1 Mpc) bears support to the hypothesis that (also) on these scales the emitting plasma is moving at highly relativistic speeds. In this case in fact the emission via inverse Compton scattering off cosmic background photons is enhanced and the resulting predicted X–ray spectrum wel...
متن کاملBlack Holes and Relativistic Jets
There is strong observational evidence that AGN, Galactic X-ray transients and (probably) γ-ray bursts are associated with black holes, and that these sources are able to form collimated, ultrarelativistic outflows. There is much interest in trying to understand how these prime movers are able to release energy from accreting gas and their own spin energy. Electromagnetic field plays a large ro...
متن کاملRelativistic Jets in Collapsars
We examine the propagation of two-dimensional relativistic jets through the stellar progenitor in the collapsar model for gamma-ray bursts (GRBs). Each jet is parameterized by a radius where it is introduced, and by its initial Lorentz factor, opening angle, power, and internal energy. In agreement with previous studies, we find that relativistic jets are collimated by their passage through the...
