Ultra-relativistically hot jets (Kohler et al. 2012 ; Kohler and Begelman 2015 ) in power-law atmospheres with \(\pmb{\kappa=8/3,7/3}\) and 2 (from left to right). The color-coded images show the distribution of the Lorentz factor. The initial Lorentz factor is \(\Gamma_{0}=50\) and opening angle \(\theta_{0}=1/\Gamma_{0}\).
