Gravitational Waves and Cosmic Microwave Background

As part of the Theoretical Particle Physics & Cosmology group at the Niels Bohr Institute, we conduct research in CMB science using data from the Planck satelite and the planned Deep Space experiment in Greenland. We also study gravitational waves using data from the LIGO observatories.
