Bonn

Frank Bertoldi

Frank Bertoldi ARC node representative

Professor at the Argelander Institute for Astronomy at the University of Bonn

Phone: +49 (0)228 - 73 - 6789
Fax: +49 (0)228 - 73 - 1775

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 interests cover molecular cloud structure, star formation, Kuiper belt objects, comets, PDRs, and gamma-ray bursts.

Stefanie Mühle

Stefanie Mühle ARC node manager

Postdoc; mmVLBI, user support, training, outreach

Phone: +49 (0)228 - 73 - 3662
Fax: +49 (0)228 - 73 - 1775

Research Interests: properties of the molecular gas in extreme environments like galaxy mergers, starburst galaxies, and near AGN, and in more "normal" nearby galaxies (observations, non-LTE modelling); star formation and feedback; the ISM in the Galactic center; Galactic masers; magnetic fields in nearby galaxies

Benjamin Magnelli

Benjamin Magnelli Postdoc; CASA, user support

Phone: +49 (0)228 - 73 - 5768
Fax: +49 (0)228 - 73 - 1775

Research Interests: My field of activity is the formation and evolution of high-redshift galaxies, and in particular the study of the mechanisms triggering and regulating their star-formation activities. My studies are mainly based on infrared/submm/mm observations of the dust and molecular gas of large sample of high-redshift galaxies.

Lydia Moser

Lydia Moser Postdoc; data combination, CASA, user support

Phone: +49 (0)228 - 73 - 5768
Fax: +49 (0)228 - 73 - 1775

Research Interests: 1) spatially resolved mm/sub-mm observations of nearby AGN galaxies ('LLQSOs', z<0.06): properties of the molecular gas (distribution, kinematics, excitation/chemistry); fueling (inflow) vs. feedback (outflows); relation between nuclear activity and host galaxy properties depending on redshift; black hole - bulge growth; star formation; evolution of galaxies 2) high resolution (<1'' (= 0.04pc)) mm/sub-mm observations of the central parsec of the Milky Way: properties of the ISM impacted by the supermassive black hole Sagittarius A* (Sgr A*) and the nuclear stellar cluster; mystery of recent star formation despite the harsh environment; matter supply for accretion onto Sgr A*
