Overview

Welcome to MPIA's research group on the topic of "Coevolution of Galaxies and Black Holes", headed by Dr. Knud Jahnke. The group was funded by the Emmy Noether Programme of the German Science Foundation DFG between 2007 and 2014, and has since merged with the Euclid group at MPIA (also headed by Knud Jahnke).

A number of projects study 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.

Project areas

Individual project areas are:

  • Studying the incidence of merging of galaxies for active galaxies across redshifts, masses, and accretion rates, 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 or VLT images as a function of time since a galaxy merger.

Datasets include:

  • The highest mass black holes at z=2 published in APJ; 19 QSOs observed with the HST
  • The highest local black holes (z=0.2), observed with FORS and VIMOS. Analysis mainly done, publication in preparation.
  • The highest accretion rate black holes at z=2 with Cycle 23 HST images on 21 QSOs.
  • The highest accretion rate black holes at z=0.2 with VLT FORS imaging data to be observed in P98, as well as data from Subaru.
