Domain of Influence Analysis: Implications for Data Assimilation in Space Weather Forecasting
Frontiers in Astronomy and Space Sciences, 2020 Solar activity, ranging from the background solar wind to energetic coronal mass ejections (CMEs), is the main driver of the conditions in the interplanetary space and in the terrestrial space environment, known as space weather.

Synchrotron Firehose Instability
The Astrophysical Journal, 2023 We demonstrate using linear theory and particle-in-cell (PIC) simulations that a synchrotron-cooling collisionless plasma acquires pressure anisotropy and, if the plasma beta is sufficiently high, becomes unstable to the firehose instability, in a ...

Azimuthal anisotropy of jet quenching at LHC [PDF]
, 2001 We analyze the azimuthal anisotropy of jet spectra due to energy loss of hard partons in quark-gluon plasma, created initially in nuclear overlap zone in collisions with non-zero impact parameter.

Dense astrophysical plasmas [PDF]
Journal of Physics: Condensed Matter, 2002 We briefly examine the properties of dense plasmas characteristic of the atmospheres of neutron stars and of the interior of massive white dwarfs. These astrophysical bodies are natural laboratories to study respectively the problem of pressure ionization of hydrogen in a strong magnetic field and the crystallization of the quantum one-component-plasma
