My Publications


      And subdivided into topics : 



My main area of research is observational cosmology and the use of Type Ia supernovae to measure distances in the universe. I am member of the Supernova Cosmology Project (SCP) that discovered the accelerated expansion of the Universe and the associated ”dark energy”.  I shared the 2007 Gruber Prize in Cosmology and the Breakthrough Prize in Fundamental Physics in 2015 with my SCP colleagues. Furthermore, our team leader, Saul Perlmutter, shared the 2011 Nobel Prize in Physics. I have also received the Gustafsson Prize in 2004.

Since 2013 I lead the cosmological studies using Type Ia supernovae within the intermediate Palomar Transient Factory. In 2018 we start the much upgraded Zwicky Transient Facility at the Palomar Observatory.

You can read about my research group here and my publications. Since 2017 I am leading the GREAT research environment funded by the Swedish Research Council. In this project, we study sources of gravitational waves and their electromagnetic counterparts

In the past, I have also worked in experimental particle physics, searching for the Higgs boson at CERN and in the area of high-energy neutrino astrophysics using the AMANDA/IceCube telescope at South Pole.
