Synchrotron-cooled plasma distribution in the outer magnetosphere of a neutron star
Mikhail V. Medvedev, Anatoly Spitkovsky, Alexander Philippov
The guiding center formalism is employed to analyze the motion of a charged relativistic particle in an inhomogeneous magnetic field, subject to magnetic mirroring and energy loss…
Whistler-Alfvén turbulence in a non-neutral ultrarelativistic pair plasma
Stanislav Boldyrev, Mikhail Medvedev
The large-scale dynamics of most conventional space and astrophysical plasmas are predominantly governed by Alfvén modes, which are low-frequency magnetohydrodynamic modes existing…
Electron-positron cascade in magnetospheres of supermassive Kerr black holes and the origin of relativistic AGN jets
Mikhail V. Medvedev, Andrzej A. Zdziarski
The avalanche mechanism of plasma production in active galactic nuclei (AGNs) is detailed, and constraints on system parameters required for efficient electron-positron pair cascad…
Origin of spectral bands in the Crab pulsar radio emission
Mikhail V. Medvedev
The model explaining the spectral "zebra" pattern of the high-frequency interpulse (HFIP) of the Crab pulsar radio emission is proposed. The observed emission bands are diffraction…
Pair Plasma Cascade in Rotating Black Hole Magnetospheres with Split Monopole Flux Model
Michael C. Sitarz, Mikhail V. Medvedev, Alex L. Ford
An electron-positron cascade in the magnetospheres of Kerr Black Holes (BH) is a fundamental ingredient to fueling the relativistic -ray jets seen at the polar regions of galact…
Simulation of the isotropic ultra-high energy photons flux in the solar magnetic field and a comparison with observations made by the HAWC and Fermi-LAT observatories
David Alvarez-Castillo, Piotr Homola, Bożena Poncyljusz +37
In this contribution we study the possibility of the formation of cosmic ray ensembles (CRE) created by the interaction of ultra-high energy (UHE) photons with the magnetic field o…
Extreme Plasma Astrophysics
D. Uzdensky, M. Begelman, A. Beloborodov +22
This is a science white paper submitted to the Astro-2020 and Plasma-2020 Decadal Surveys. The paper describes the present status and emerging opportunities in Extreme Plasma Astro…
On Poynting-Flux-Driven Bubbles and Shocks Around Merging Neutron Star Binaries
M. V. Medvedev, A. Loeb
Merging binaries of compact relativistic objects (neutron stars and black holes) are thought to be progenitors of short gamma-ray bursts and sources of gravitational waves, hence t…
