Constraining Active Galactic Nucleus Jets with Spectrum and Core Shift: The Case of M87
Kouichi Hirotani, Hsien Shang, Ruben Krasnopolsky +3
We analytically model stationary and axisymmetric active galactic nucleus jets, assuming energy conservation along each magnetic flux tube. Using very-long-baseline interferometry…
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…
How Does a Protostar Form by Magnetized Gravitational Collapse?
Indrani Das, Hsien Shang, Ruben Krasnopolsky
Star formation through the dynamical magnetized collapse remains an active area of astrophysical research. We carry out a comprehensive exploration on the magnetized gravitational…
Interaction of large- and small-scale dynamos in isotropic turbulent flows from GPU-accelerated simulations
Miikka S. Väisälä, Johannes Pekkilä, Maarit J. Käpylä +3
Magnetohydrodynamical (MHD) dynamos emerge in many different astrophysical situations where turbulence is present, but the interaction between large-scale (LSD) and small-scale dyn…
Two-dimensional Particle-in-Cell simulations of axisymmetric black hole magnetospheres
Kouichi Hirotani, Ruben Krasnopolsky, Hsien Shang +2
We investigate the temporal evolution of an axisymmetric magnetosphere around a rapidly rotating, stellar-mass black hole, applying a two-dimensional particle-in-cell simulation sc…
