This applet calculates the propagation of a relativistic jet within a cold spherically symmetric external medium. It is based on the analytic theory developed in Bromberg et al. (2011) and the numerical tests and calibration carried out in Harrison, Gottlieb
Nakar (2017), where a description of the algorithm is given in the appendix.
To use the applet please insert the jet properties and density profile. Select between three types of density profiles: (i) A power-law,
. (ii) An analytic stellar-like profile,
. Define the stellar radius and mass. (iii) A custom density profile. Paste the density profile in two columns [r
], without commas or parentheses. Note that the analytic model is applicable only for density profiles that do not vary on a scale that is much smaller than r and that are
not too steep (
