Hybrid Numerical Simulations of Pulsar Magnetospheres
Ioannis Contopoulos, Jerome Petri, Petros Stefanou
We continue our investigation of particle acceleration in the pulsar equatorial current sheet (ECS) that began with Contopoulos (2019) and Contopoulos & Stefanou (2019). Our basic…
A ring-of-fire in the pulsar magnetosphere
Ioannis Contopoulos, Petros Stefanou
Contopoulos 2019 proposed that a dissipation zone develops in the magnetosphere of young pulsars at the edge of the closed-line region beyond the light cylinder. This is necessary…
A Cosmic Battery in accretion flows around astrophysical black holes
Ioannis Contopoulos
We present our view of the immediate environment of an astrophysical black hole. We discuss the origin of the electron-positron and electron-proton jet components, and the origin o…
Generation and transport of magnetic flux in accretion-ejection flows
Ioannis Contopoulos
Astrophysical accretion flows are associated with energetic emission of radiation and outflows (winds and jets). Extensive observations of these two processes in X-ray binary outbu…
