Markus R. Mosbech

Cosmology and Astroparticle Physics

About Me

I am a postdoc at RWTH Aachen and KIT in Germany, previously I completed my PhD at The University of Sydney working on cosmology and astroparticle physics.

I use cosmology to investigate the nature of dark matter through the use of linear and nonlinear numerical tools. In particular, I have worked on constraining interactions between dark matter and neutrinos, using existing CMB data as well as forecasts for future 21cm observations and gravitational waves.

I am interested in using numerical tools to help us investigate the nature of our universe, in conjunction with novel cosmological and astrophysical observations. I have released an extension to the Boltzmann solver CLASS for treating dark matter interacting with massive neutrinos, and contributed to the development of Gadget-4-CPPC, an extension of the Gadget-4 N-body code for treating hot dark matter subcomponents, as well as the OLÉ emulator for accelerating cosmological inference.

In Sydney, I was part of the Astroparticle Group, as well as the Arc Centre of Excellence for Dark Matter Particle Physics and the Sydney Consortium for Particle Physics and Cosmology.

Finally, if you think my research sounds interesting and you would like to hear more, or have an idea that you want to collaborate on, please get in touch!
