Scientific collaboration is one of the main strengths of MPIA as an institution. In this tradition, the following group of talented astronomers further their research through ingenuity, perseverance, collaboration, and efficient use of the facilities MPIA provides.
Bernd is trying to unravel the link between Active Galactic Nuclei and their host galaxies in terms of scaling relations, powerful outflows and feedback with the aid 3D spectroscopy and multi-wavelenght observations. He is the PI of the CARS survey www.cars-survey.org. Right now he is pushing his work to higher redshifts in preparation for the James Webb Space Telescope to be launched in 2018.
Laura uses variable Cepheid stars as distance indicators and stellar tracers to investigate the structure, the dynamics and the chemical content of young stellar populations in the Milky Way disk and satellites. [more]
Jan is trying to constrain the Milky Way evolution by reproducing elemental abundance data using Chempy, a flexible chemical evolution code. He also predicts starcounts for survey proposals.
Allison uses a combination of optical data from the Dragonfly Telephoto Array (a telescope optimized for the detection of low surface brightness emission) and the Illustris cosmological hydrodynamic simulations to quantify the stellar halos of nearby galaxies as a metric for their individual accretion histories. She is also interested in the detection and characterization of LSB satellite galaxies and ultra-diffuse galaxies.
Melissa's interests are understanding the formation of the Milky Way via analysis of its stellar population, the Galactic Bulge and data-driven models.
Johanna is interested in the relation between chemical abundances and orbits of stars in the Milky Way and what it can teach us about the structure and formation of our Galaxy.
Neige is interested in the Milky-Way disk's secular evolution. In particular, she works on constraining the rate of stellar radial migration - how far stars can get from their birth orbit - using 'ultra weak chemical tagging'.
Irina Smirnova-Pinchukova (IMPRS)
Irina works with Bernd Husemann on the CARS project: www.cars-survey.org. She compares different star formation tracers to figure out how AGN affects its host galaxy.
Anna is on a one-year Fulbright grant at the MPIA, and is interested in applying machine learning techniques to data from large spectroscopic surveys. Starting in Fall 2015, she will be a graduate student at Caltech.
