معرفی
Dr. Sebastian Grandis is a Scientific Staff member at the Institute for Astro- and Particle Physics, Faculty of Mathematics, Computer Science and Physics, University of Innsbruck. His research is centered on extragalactic astrophysics, with a focus on galaxy clusters, cosmology, and weak gravitational lensing.
Research Interests:
- Galaxy cluster cosmology via number counts and mass calibration
- Weak gravitational lensing and cosmic shear
- Multi-wavelength analysis (X-ray, SZ, optical) of galaxy clusters
- Large-scale structure and dark energy
- Systematic effects in cluster selection and lensing measurements
His recent publications (2023–2025) highlight a strong focus on cosmological constraints derived from galaxy cluster abundance and weak lensing, leveraging data from major surveys including eROSITA, DES, SPT, Euclid, and HSC. His work frequently involves cross-calibration of mass estimates and modeling of baryonic and selection effects.
