TL;DR
This paper reviews recent advances in understanding high-energy gamma-ray jets, focusing on theoretical interpretations of VHE emission, blazar spectra, GRB outflows, and the implications of thermal emission observations.
Contribution
It provides a comprehensive review of recent theoretical developments in high-energy jet emissions, linking observations to jet composition and energy dissipation models.
Findings
VHE gamma-ray emission from M87 and other blazars can be explained by specific jet models.
The GeV spectral breaks are linked to opacity effects in the broad line region.
Detection of GeV emission from GRBs impacts models of magnetic outflows.
Abstract
A recent progress in the study of -ray jets is reviewed, with a focus on some theoretical interpretations of the VHE emission from M87, and possibly other misaligned blazars; the connection betwe en the GeV breaks exhibited by bright LAT blazars and opacity sources in the broad line region; the consequences of the detection of GeV emission from GRBs to models of magnetic outf lows; and the implications of the thermal emission observed is some GRBs to dissipation of the outflow bulk energy.
