Dr. Christian Maier

Research interests

I did my PhD thesis at MPIA Heidelberg, working in the CADIS project and studying galaxies at intermediate redshifts (z<1) and at high redshifts (up to z=6). As a postdoc I joined the group of Prof. Simon Lilly at the Institute of Astronomy at ETH Zurich. I was a key person (being also the zCOSMOS data manager) from the beginning in the zCOSMOS large-redshift survey collaboration, the ESO-VLT spectroscopic follow-up of COSMOS for 30 000 galaxies at z<3.5. I used and I am still using this galaxy parent sample for several spectroscopic follow-up observations. The constructive work in the zCOSMOS team has resulted in 46 publications in relevant journals since then with me involved as first author or co-author.

After my Research Team Leader (“Oberassistent”) position at ETH Zurich, I joined, as an “Universitaetsassistent”, the extragalactic group of Prof. Bodo Ziegler at the Department of Astrophysics, University of Vienna in 2011. Here in Vienna I also became a member of the team of the HST multi-cycle treasury program ”Cluster Lensing And Supernova survey with Hubble” (CLASH), I also joined the LoCuSS (Local Cluster Substructure Survey) team, and I am also involved in a collaboration with the HSC SSP (Hyper Suprime-Cam Subaru Strategic Science Program) team. At the University of Vienna I gave several lectures about “Galaxy evolution” and “Giant black holes and their host galaxies”, and I supervised master and bachelor theses. At the moment I am an external scientist at the University of Vienna.

My main research interests include:
• Evolution of Star Formation Rates and Metallicities of Galaxies
• Internal Kinematics, Stellar-to-Halo Mass Relations and Connection with Gas Regulation
• Gas Consumption and Quenching Timescales and Mechanisms
• Role of AGNs and (Cluster) Environment on Galaxy Evolution and on Quenching
• Evolution of Structural Parameters of Galaxies
• Lyman Alpha Emitters and Primeval Star Formation at High Redshifts
