Welcome to the Emmy Noether-research group at MPIA on the topic of "Coevolution of Galaxies and Black Holes", headed by Dr. Knud Jahnke. The group is funded by the German Science Foundation DFG since 09/2007.

A number of projects studies the influence and interaction of the formation of supermassive black holes in the centers of massive galaxies on the surrounding galaxy. The main aim is to constrain the relative interdependence of galaxy interactions, induced star formation, AGN activity and its effect on the migration of massive galaxies from. Keywords are: Starburst-merger-AGN connection and AGN feedback.

We highlight some of our projects - for a complete listing please see our publication page.


The group consists of:

  • Dr. Knud Jahnke (group head)
  • Robert Singh, graduate student (graduate from University Gothenburg, Sweden, since 08/2011)
  • Matt Mechtley, postdoctoral researcher (arriving 11/2013 from Arizona State University)
  • Liyualem Ambachew, master student (University of Heidelberg, from 12/2013)
Group 2010 (Nugroho, Andrae, Jahnke, Inskip, Cisternas)

Project areas

Individual project areas are:

  • Determining the bulge- or stellar mass vs. Black Hole-mass relation of galaxies out to z>2 and constrain its evolution over 10 Gyrs using data from the GEMS and COSMOS galaxy surveys with the HST and Laser Guide Star Adaptive Optics assisted Integral Field Spectroscopic data from SINFONI at ESO VLT.
  • Studying the incidence of merging of galaxies for active galaxies in COSMOS in direct comparison to inactive galaxies as a function of redshift, luminosity and environment. A crucial aspect is finding the limits of which degree of interaction can actually be seen in HST images as a function of time since a galaxy merger.
  • Studying the incidence, mass and ages of star-formation in AGN host galaxies as a function of galaxy luminosity, morphology and signs of interaction. We will use two spectroscopic datasets from FORS2 and the VIMOS IFU at ESO VLT.
  • As a separate topic: Automatic detection of the sense of rotation in spiral galaxies using advanced classification methods.
