Recent Highlights
The ‚Diamond Ring‘ in Cygnus X
First detection of a slowly expanding ring of ionized carbon in Cygnus X — interpreted as a terminal-phase stellar wind-driven bubble.
Dannhauer et al., A&A, 2025
Globules & Pillars in Cygnus X
[OI] 63μm observation of a proplyd — tracing photodissociation regions around externally irradiated globules.
Schneider, Dannhauer et al., A&A, 2025
[CII] Deficit in RCW79
Self-absorption in an ionized carbon-filled bubble explains the observed [CII]/FIR deficit in the HII region RCW79.

About Me
I am a PhD student at the University of Cologne (IMPRS for Astronomy and Astrophysics), working with Dr. Robert Simon and Dr. Nicola Schneider on massive star formation and stellar feedback in the Milky Way. I am a member of the DFG-funded SFB 1601 research center and the SOFIA FEEDBACK legacy program.
My work combines multi-wavelength observations (SOFIA, IRAM 30m/NOEMA, Herschel, APEX, …) to understand how massive stars shape their natal molecular clouds by stellar feedback and form.
Thesis: Space weather corrections for eROSITA data
Thesis: Radio AGN fraction in the first eROSITA all-sky survey

Beyond the Observatory
My freetime (if there is any left…) is mostly occupied by my second love, aviation. I hold licences for gliders and ultralights and try to spend most of my time on the airfield, where I also lead the maintenance work since several years. Many of the great pictures taken on my favourite place in the world, Segelfluggelände Lindlar, are found here.
I developed an early interest in physics and spent a fair amount of my school years building hybrid rocket engines, model airplanes and drones. After my Abitur in 2015 I began studying Physics/Astronomy in Bonn. My love for astronomy and photography came from my uncle (Andreas Kreck, the name patron for the garden observatory) who taught me a lot and whose huge collection of telescopes and gear led to its construction.
And most of all: I really like astrophotography.
Clear skies,
