Research Fellow
I am Danish astrophysicist interested in constraining particle physics from astrophysical observations such as dark matter identification, neutrino mass determination, Big Bang Nucleosynthesis etc. I did my PhD at the Dark Cosmology Centre in Copenhagen, before moving to UQ in 2010, where I currently hold a postdoc position until 2014.

| Finding the most interesting absorption systems |
Quasars provide distant but very powerful light sources. Galaxies and gas clouds along the line of sight from the quasars to us, will imprint on the quasar spectra we observe from Earth. This can be used to map the position and density of gas clumps in the Universe even though we cannot see the... |

| Measuring the first elements |
During the nucleosynthesis taking place few minutes after Big Bang deuterium (a proton plus a neutron) was the first element to form. The time of nucleosynthesis... |

| Counting the holes |
The Universe consist of dark matter structures on all scales from galaxies to super clusters. Traditionally scientists have derived cosmological properties from the distribution of structures, but lately there has been an interest in using the voids between the structures as cosmological probes... |

| Looking for dark matter emission |
Most of the matter in the Universe is in the form dark matter, of which the identity remains unknown. The sterile neutrino is a very good particle candidate for dark matter, and via neutrino-oscillations it does have a very faint observable signature (not yet observed). Recently a new method has... |
