Dr. David Bogensberger

About me:

I am an astrophysicist, specialising in investigating the physics of accretion around supermassive black holes, predominantly in the X-ray band. 

​

I grew up in Vienna, Austria, and Brussels, Belgium. I completed a Master of Physics degree at the University of Oxford in England, which I followed up with a Doctorate in Astronomy at the Max Planck Institute of extraterrestrial Physics, affiliated with the Ludwig Maximilian University of Munich in Germany. Since then, I have been working as a postdoctoral researcher at the University of Michigan in the USA.

​

My research focus has involved X-ray variability, spectroscopy, imaging, and survey analysis of active galactic nuclei (AGNs). I have also investigated jets, stellar mass black holes, and wrote a masters thesis about my search for exoplanets around a post-common envelope binary. While my main focus has been in the X-ray band, I have also analysed optical, radio, and gamma-ray data. 

​

I have experience in analysing data from eROSITA, Chandra, NuSTAR, XRISM, XMM, Swift, NICER, and Astrosat. I have developed new methods and algorithms for the analysis of AGN variability and jet proper motions. AGN spectroscopy has also been a focus of my work, specifically in the X-ray band, but also in the optical.

​

I am intrigued by the physics of accretion onto black holes, and all the questions that remain unanswered about its numerous facets, from the geometry of the accretion flow in different states, to feedback via jets and winds, as well as unusual processes that can occur in these complex environments, such as flip-flops.
