Welcome!

Dear Visitor,


I'd like to welcome you to my homepage dedicated to my professional life as an observing astrophysicist. I work on the centers of nearby galaxies, trying to observe and understand the immediate surroundings of the supermassive black holes (SMBH) that lurk there. Many of these SMBH actively accrete material from their surroundings creating "bright fireworks" that can be observed all throughout the electromagnetic spectrum.


Here you will not only find all relevant information about me and my research but I will also post once in a while interesting information I encounter during my work.


Please feel free to contact me in case of questions or directly comment on my entries!

Resolving the dust structure in active galactic nuclei

Colloquium talk given at the Observatory of Belgrade in 2017 as an overview of high angular resolution imaging of AGN

The nuclei of many galaxies shine bright throughout all the electromagnetic spectrum. This powerful emission if often brighter than all the star light of the galaxy combined. Its source is an accreting supermassive black hole in the galaxy center. However, around half of the accretion disk emission does not escape the nuclear region but is instead absorbed by an unknown dust structure and reemitted in the infrared. I will present an overview of our attempts to detect and resolve this dust structure in nearby active galactic nuclei (AGN) and review the surprising results emerging from recent highest angular resolution observations.
