German ARC staff

The German ALMA regional center node exists within the collaboration "Research Association for Interferometry in Northrhine-Westfalia" consisting of the Bonn and Cologne universities and the Max-Planck Insitut für Radioastronomie. The ARC is located at the Argelander-Institut für Astronomie of Bonn University.

The people currently involved with the German ARC are listed below. The email addresses are listed here.

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: Within the field of observational cosmology, I study the formation and evolution of galaxies, mainly with respect to their growth over cosmic time. Therefore I am interested in the measurement of star formation activity within galaxies to very large lookback times and employ data from deep field observations, particularly at long (far-infrared to radio) wavelengths. In this wavelength regime it is possible to probe the thermal emission from interstellar dust that absorbs the ultraviolet light from young stars, the gas reservoir fueling the production of new stars as well as non-thermal processes potentially linked to recent events of star formation.

Together with Thibault Cavalier (Bordeaux) I currently act as the representative for the European CASA users within the international CASA users committee (CUC). The CUC provides independent feedback and suggestions for CASA improvement to the CASA software development group. Any CASA user is hence kindly asked to report any suggestions for CASA improvement to their respective regional representative in the CUC.

Professor for experimental astrophysics at the I. Physikalische Institut in Cologne

Phone: +49 (0)221 - 470 - 1935
FAX: +49 (0)221 - 470 - 5162

Research interests: formation of massive stars, astrochemistry and formation of molecular clouds, articularly on the modeling of observing data. I am Project leader of Projects A6 and C3 in the new SFB 956, co-I of Herschel/HIFI and have been involved there in the GT KPs HEXOS and CHESS. From 1997 to 2010 I have been member of various ALMA committees, among the Science Software Requirements, ESAC and ASAC and various review committees.
