Research Interests: My currrent research focuses on the formation of stars, galaxies, and massive black holes in the early Universe, and on a project to constrain structure formation and cosmological parameters (primordial density spectrum, dark energy) by means of a Sunyaev-Zel'dovich galaxy cluster survey. My minor insterest cover molecular cloud structure, star formation, Kuiper belt objects, comets, PDRs, and gamma-ray bursts.

Research Interests: Sunyaev-Zel'dovich effect in the clusters of galaxies, physics of the intra-cluster medium and galaxy cluster mass scaling relations, radio and sub-millimeter galaxies in the cluster fields, radio recombination lines from starburst galaxies at the millimeter/sub-millimeter wavelengths, dust and synchrotron emissions from supernova remnants

Research Interests: My current research focuses on weak gravitational lensing of galaxy clusters. My future work will combine the mass estimates of weak gravitational lensing with mass estimates using the Sunyaev-Zel'dovich effect. Other research interests are multiwavelength observations and variability studies of AGN.

Research Interests: My research focuses on modeling the gas and dark matter distributions inside galaxy clusters from multi-wavelength observations, in particular using the data on the Sunyaev-Zel'dovich effect from the APEX-SZ experiment. I investigate the merits and limitations of different theoretical methods to perform this joint analysis.

Phone: +49 (0)228 - 73 - 6786
Fax: +49 (0)228 - 73 - 1775

Research interests: I am interetsted in multi-wavelength observations of clusters of galaxies; in particular observations of the Sunyaev-Zel'dovich effect and the joint analysis with data from other wavelengths (X-ray, optical) to constrain the thermodynamic state of the intra-cluster gas. I am also active in the development of data analysis tools such as de-convolution algorithms for the recovery of extended emission in bolometric differential observations of galaxy clusters.
