The research of our group is dedicated to the Evolution of Starforming Galaxies and focuses on the Theory of the Interstellar and Intergalactic medium, the acceleration and propagation of high energy particles, and the interpretation of their observational signatures mainly in X-rays, UV, as well as in gamma-rays and radio continuum. Our approach is basically theoretical (both analytical and numerical), but tightly connected to observations.

I. Theory of the Interstellar Medium (ISM)

Main research topics:

• Dynamical evolution of ISM on large and small scales

• Study of interstellar turbulence and its effect on ISM structure

• Investigation of interaction of ISM components

• Local Bubble and neighbouring superbubbles

• Comparison of models with observations (from radio to X-rays)

II. Theory of the Intergalactic Medium (IGM)

Main research topics:

• Dynamical evolution of galactic outflows (galactic fountains and winds)

• Non-equilibrium ionization (NEI) modeling of hot plasmas

• Self-consistent dynamical and thermal modeling of soft X-ray spectra in galactic halos

• Study of metal injection into IGM by winds and ram pressure stripping

• Modeling of IGM features in galaxy groups

III. Origin and Propagation of Cosmic Rays

Main research topics:

• Cosmic ray and MHD wave driven galactic winds

• Transport of cosmic ray nucleons and modeling of diffuse gamma-ray emission

• Transport of cosmic ray electrons and modeling of radio continuum emission

• Acceleration of cosmic rays in galactic outflows
