Relativistic wind from a magnetic monopole rotator
Rui Hu, Andrei M. Beloborodov, Alexander Y. Chen
A rotating star with a monopole (or split monopole) magnetic field gives the simplest, prototype model of a rotationally driven stellar wind. Winds from compact objects, in particu…
Radiation GRMHD simulations of M87: funnel properties and prospects for gap acceleration
Philippe Z. Yao, Jason Dexter, Alexander Y. Chen +2
We use the public code ebhlight to carry out 3D radiative general relativistic magnetohydrodynamics (GRMHD) simulations of accretion onto the supermassive black hole in M87. The si…
Coherent emission from QED cascades in pulsar polar caps
Fábio Cruz, Thomas Grismayer, Alexander Y. Chen +2
Pulsar magnetospheres are thought to be filled with electron-positron plasma generated in pair cascades. The driving mechanism of these cascades is the emission of gamma-ray photon…
Plasmoid ejection by Alfvén waves and the fast radio bursts from SGR 1935+2154
Yajie Yuan, Andrei M. Beloborodov, Alexander Y. Chen +1
Using numerical simulations we show that low-amplitude Alfvén waves from a magnetar quake propagate to the outer magnetosphere and convert to "plasmoids" (closed magnetic loops) wh…
A Numerical Model for the Multi-wavelength Lightcurves of PSR J0030+0451
Alexander Y. Chen, Yajie Yuan, Georgios Vasilopoulos
Recent modeling of Neutron Star Interior Composition Explorer(NICER) observations of the millisecond pulsar PSR J0030+0451 suggests that the magnetic field of the pulsar is non-dip…
Filling the Magnetospheres of Weak Pulsars
Alexander Y. Chen, Fabio Cruz, Anatoly Spitkovsky
Recent advances in numerical algorithms and computational power have enabled first-principles simulations of pulsar magnetospheres using Particle-in-Cell (PIC) techniques. These ab…
