Alexander Dybdahl Rathcke

Alexander Dybdahl Rathcke is a Postdoctoral Researcher (Research Fellow) at the Department of Space Research and Technology, Technical University of Denmark (DTU Space), specializing in exoplanet atmospheric characterization using space-based observatories including Hubble and James Webb Space Telescopes. His work focuses on developing advanced data analysis techniques to interpret transmission spectra and correct for stellar contamination.

Education:

• PhD in Exoplanetary Atmospheres, Technical University of Denmark (2019-2022)

Rathcke's research spans terrestrial exoplanets, hot Jupiters, and sub-Neptune atmospheres, with expertise in transmission spectroscopy, stellar activity mitigation, and machine learning applications. He actively develops computational frameworks like TAU for telluric correction and contributes to major observational campaigns such as the TRAPPIST-1 JWST Community Initiative. His fingerprint reveals deep specialization in planetary atmospheres (90%), transmission spectra (81%), hot Jupiters (71%), and space telescope instrumentation.

Recent publications demonstrate a clear trajectory toward characterizing Earth-like exoplanets using JWST, with increasing emphasis on stellar contamination correction and neural network-based data processing. His work bridges observational astronomy, atmospheric physics, and computational methods to advance exoplanet science.
