About me

I am Senior Astronomer in the Astronomy Group at ASTRON and I am Professor of Astronomy at the Kapteyn Institute at the University of  Groningen (NL).

My research interests:
study of the gas and its role in active galactic nuclei. I look at the interaction between the gas and the radio plasma and exploring the life-cycle of radio sources using low frequency observations (LOFAR) and the combination LOFAR-Apertif.
More in general, I am interested on the role of gas (and in particular neutral hydrogen @ 21 cm and cold molecular gas) in the evolution of early-type galaxies.

One night I was, as usual, observing the sky with my telescope. I noticed that a sign was hanging from a galaxy a hundred milion light-years away. On it was written: I SAW YOU.
