Assist. Gregor Rihtaršič

I am a graduate student in the astronomy group of the Faculty of Mathematics and Physics under the supervision of Prof. Dr. rer. nat. Maruša Bradač. I obtained my Bachelor's degree in Physics at the Faculty of Mathematics and Physics in Ljubljana and my Master's degree in Astrophysics at the Ludwig Maximilian University in Munich. I am particularly interested in the field of extragalactic astronomy.

My main area of research is strong gravitational lensing in galaxy clusters. I am a member of the CANUCS collaboration (CAnadian NIRISS Unbiased Cluster Survey, https://niriss.github.io/), which is studying the early Universe and the first galaxies with observations from the James Webb Space Telescope (JWST). Within the collaboration, I am mainly working on the development of new models of the mass distribution in massive galaxy clusters using new catalogues of multiply lensed galaxies made possible by JWST observations.
