Structure of the Universe


Gabor Racz was born and raised in Veszprem, Hungary. He received his B.Sc., M.Sc. and Ph.D. in Eotvos Lorand University, Budapest, where he studied alternative models of dark energy and worked on non-periodic cosmological zoom-in simulations. His research focuses on cosmological structure formation, the effects of the large-scale structures on the measurements, and numerical methods in cosmology.


B.Sc: 2013, and M.Sc: 2015 in Physics, and Ph.D., 2021 in Physics and Astronomy, Eotvos Lorand University, Budapest.
