Our Group

Prof. Cristiano Porciani leads the astrophysics and cosmology research group at the Argelander-Institut für Astronomie. The group comprises several postdoctoral researchers, graduate students and masters students actively involved in studies of the large scale structure of the Universe, primordial non-Gaussianities, the physics of the inter-galactic medium, and galaxy formation. All members use an arsenal of both analytic and numerical tools to advance our understanding of the origin and evolution of structure in the Universe.

More information on each member can be found below.
