I am Professor for Astronomy at the Hamburger Sternwarte (observatory), which is part of the Department of Physics of the University of Hamburg. I served as Dept. Chair from 01/2014 until 12/2015, as Deputy Dept. Chair for 3.5 years and as Managing Director of the observatory for 3 years.

My main area of research is the modeling of stellar and planetary atmospheres using computer simulations with our PHOENIX code. This is a large scale supercomputing application, my group regularily uses large parallel supercomputers that can be found in the top 10 of the world's fastest supercomputers. My CV is available as PDF file and I also have a list of publications available (PDF, infrequently updated, please use ADS for up-to-date information!). I am a member of the Lothar Collatz Center for Computing in Science. My group has often opportunities for Bachelor & Master theses in the field of theoretical and computational astrophysics, please contact me for more information.

Vorlesungsinfos

Im SoSe 2022 halte ich die Vorlesungen "Einführung in die Astronomie II" (für Studierende in einem BSc. Studiengang der MIN) und "Sterne, Galaxien, und das Universum" (für Hörer aller Fakultäten), sowie das Seminar "Moderne Probleme der Stellarastrophysik" und das Proseminar "Moderne Probleme der Stellarastrophysik" sowie die Spezialvorlesung Theorie und Praxis von Phoenix (Vorkenntnisse sind unabdingbar erforderlich!). Eine Anmeldung zur Vorlesung und den Seminaren ueber Stine ist zwingend notwendig, Vortraege im (Pro)Seminar koennen nur nach erfolgreicher Anmeldung in Stine vergeben werden (alles total voll, sorry!). Details werde ich ueber Stine emails an die angemeldeten Studierenden verschicken.

My main research interests are (not necessarily in this order):

(More information can be found on the PHOENIX homepage)

3D radiative transfer algorithms and their implementation.
continue the development & verification of PHOENIX/3D.
The atmospheres and spectra of novae, M dwarfs & giants, Brown Dwarfs, L/T dwarfs, T Tauri's, SNe, basically everything that radiates.
Irradiation of planets and secondaries of CVs
Analyses of Nova, M/L/T dwarf & giant, Brown Dwarf, T Tauri, and SN spectra.
The detailed physics of nova spectra, in particular line blanketing and NLTE effects.
Numerical methods for NLTE and radiative transfer calculations.
Line formation, blending and blanketing in (relativistically) expanding atmospheres.
Radiative transfer in relativistically expanding, spherical atmospheres.
Detailed NLTE calculations for extremely large model atoms.
Effective numerical methods to treat 100's of millions spectral lines individually with detailed profiles.
Molecular line opacities.
Line broadening in very cool stars.
Finishing the next versions of the M/L/T-O dwarf and nova model grids.
Models for Stellar Winds
Keeping PHOENIX/1D and PHOENIX/3D alive and happy (currently at version 18.5 with a host of new and beautiful arcan bugs!).
