Efficient cosmological parameter sampling using sparse grids
Mona Frommert, Dirk Pflueger, Thomas Riller +3
We present a novel method to significantly speed up cosmological parameter sampling. The method relies on constructing an interpolation of the CMB-log-likelihood based on sparse gr…

Reconstruction of signals with unknown spectra in information field theory with parameter uncertainty
Torsten Ensslin, Mona Frommert
The optimal reconstruction of cosmic metric perturbations and other signals requires knowledge of their power spectra and other parameters. If these are not known a priori, they ha…
