CosmicNet I: Physics-driven implementation of neural networks within Boltzmann-Einstein solvers
Jasper Albers, Christian Fidler, Julien Lesgourgues +2
Einstein-Boltzmann Solvers (EBSs) are run on a massive scale by the cosmology community when fitting cosmological models to data. We present a new concept for speeding up such code…
Lensing anomalies from the epoch of reionisation
Christian Fidler, Julien Lesgourgues, Christophe Ringeval
Reionisation blurring is a non-linear correction to the cosmic microwave background that acts similar to weak gravitational lensing and that can be computed from linear perturbatio…
The large-scale general-relativistic correction for Newtonian mocks
Julian Adamek, Christian Fidler
We clarify the subtle issue of finding the correct mapping of Newtonian simulations to light-cone observables at very large distance scales. A faithful general-relativistic interpr…
