High-energy radiation from the pulsar Equatorial Current Sheet
Ioannis Contopoulos, Jerome Petri, Ioannis Dimitropoulos
Pulsars emit beams of radiation that reveal the extreme physics of neutron star magnetospheres. Yet, their understanding remains incomplete. Recent global Particle-in-Cell (PIC) si…
The 3D pulsar magnetosphere with machine learning: first results
Ioannis Dimitropoulos, Evaggelos Chaniadakis, Ioannis Contopoulos
All numerical solutions of the pulsar magnetosphere over the past 25 years show closed-line regions that end a significant distance inside the light cylinder, and manifest thick st…
Flares from plasmoids and current sheets around Sgr A*
I. Dimitropoulos, A. Nathanail, M. Petropoulou +2
The supermassive black hole Sgr A* at the center of our galaxy produces repeating near-infrared flares that are observed by ground and space based instruments. This activity has be…
A new solution of the pulsar equation
Ioannis Contopoulos, Ioannis Dimitropoulos, Dimitris Ntotsikas +1
We present the first new type of solution of the pulsar equation since 1999. In it, the whole magnetosphere is confined inside the light cylinder and an electrically charged layer…
The Pulsar Magnetosphere with Machine Learning: Methodology
Ioannis Dimitropoulos, Ioannis Contopoulos, Vassilis Mpisketzis +1
In this study, we introduce a novel approach for deriving the solution of the ideal force-free steady-state pulsar magnetosphere in three dimensions. Our method involves partitioni…
