Edvard Mörtsell

Edvard Mörtsell is a Professor in Observational Cosmology at the Department of Physics (Fysikum) of Stockholm University. He is affiliated with the CoPS group (Cosmology, Particle astrophysics, and String theory) and the Oskar Klein Centre at AlbaNova University Center. His research focuses on dark energy, dark matter, and the dynamics of cosmic expansion, particularly through gravitational lensing and supernova observations. Key projects include addressing the Hubble tension using lensed supernovae and exploring new physics beyond the Standard Model.

His research groups include 'Gravity and High Energy Theory' and 'Cosmology,' with projects like 'Charting new physics with time-domain astronomy' and 'Hubble trouble: A new measure of universal expansion.' He leads efforts to use supernovae as distance indicators and DESI BAO data to refine cosmological models. Notable contributions include bimetric gravity studies and gravitational lensing analyses of Type Ia supernovae.

Publications emphasize observational cosmology and theoretical frameworks, such as bimetric gravity's viability and dark energy constraints. Mörtsell's work bridges astrophysical observations with fundamental physics questions about the universe's structure and expansion.
