Research
I am junior professor of Radio Astronomy at the Astronomical Institute of Ruhr University Bochum (AIRUB). My research group uses radio telescopes around the world to study particle acceleration and magnetic fields in cosmic structures—from individual galaxies to galaxy groups and clusters.
We analyze multi-wavelength indicators of star formation in all types of galaxies: from dwarf galaxies to the most massive galaxies. We examine how the surrounding environment influences the evolution of these galaxies. In the context of galaxy groups and clusters, my group also investigates the physics of various particle acceleration mechanisms that drive diffuse radio emissions on large scales. The synchrotron emission associated with these environments reflects cosmic-ray electrons and magnetic fields on various scales, and we use multi-wavelength data to investigate the nature and distribution of these non-thermal components. In addition, we are on the lookout for all unusual and fascinating sources discovered by the evolving Pathfinder and Precursor instruments for the Square Kilometre Array (SKA).
My area of expertise is radio astronomy at long wavelengths, with a particular focus on analyzing data from the LOw-Frequency ARray (LOFAR), the Murchison Widefield Array (MWA), the Australian Square Kilometre Array Pathfinder (ASKAP), and the MeerKAT telescope in South Africa.
