R-JET: A postprocessing code for radiative transport in relativistic jets
Kouichi Hirotani, Hsien Shang, Ruben Krasnopolsky +1
We describe a post-processing radiative transport code for computing the spectra, the coreshift, and the surface-brightness distribution of special relativistic jets with arbitrary…

Synthetic Spectra from Particle-in-cell Simulations of Relativistic Jets containing an initial Toroidal Magnetic Field
Ioana Dutan, Kenichi Nishikawa, Athina Meli +6
The properties of relativistic jets, their interaction with the environment, and their emission of radiation can be self-consistently studied by using collisionless particle-in-cel…

Formation of limb-brightened radio jets by angle-dependent energy extraction from rapidly rotating black holes
Kouichi Hirotani, Hsien Shang, Ruben Krasnopolsky +1
By general relativistic magnetohydrodynamic simulations, it is suggested that the rotational energy of a rapidly rotating black hole (BH) is preferentially extracted along the magn…
