Bram Venemans' homepage










I am a research staff scientist working at the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany. My research topics include the discovery of black holes in the early Universe, the characterisation of the galaxies hosting these distant black holes, the Epoch of Reionisation and the galaxy environment of active galaxies.

We recently discovered the most distant quasar currently known and its host galaxy! Here is a press release describing our discovery which is published in Nature and ApJ Letters.

My research is described in more detail here , or look at my publication list and cv.
