Project description

We are searching for a outstanding individual to conduct original research on modelling and/or analysis of Type Ia supernova observations for precision cosmology. Funded by a Wallenberg Foundation research project grant to Hiranya Peiris, Jens Jasche, Ariel Goobar, Jesper Sollerman, and Matthew Hayes, the positions are focussed on our involvement in the Legacy Survey of Space and Time (LSST) and the LSST Dark Energy Science Collaboration, preparing for upcoming data from the Vera C. Rubin Observatory.

The successful candidate will be part of the Oskar Klein Centre for Cosmoparticle Physics ( in Stockholm, a rich scientific environment that comprises more than a hundred researchers working in both theory and experiment in the fields of astronomy, astrophysics and particle physics at both Stockholm University and the Royal Institute for Technology.

The OKC hosts a vibrant research program on dark matter, dark energy, transient, astrophysics, multimessenger, structure formation, and related particle physics questions. The postdoctoral associate are welcome to participate in Scientific Programs at Nordita which bring together groups of leading experts to work on specific topics for extended periods.

Main responsibilities

The position involves original research with Ariel Goobar on precision measurements of cosmological distances using Type Ia supernova observed with ZTF and LSST. The goal is to perform very competitive tests of fundamental physics and cosmology. Daily responsibilities will include collaborative work to come up with high-precision flux measurements of supernova light: adapting, developing and applying techniques for accurately separating the supernova and galaxy fluxes.
