Future cosmic microwave background (CMB) and large-scale structure (LSS) observations will provide us with percent-level measurements of the radiation content of the universe. I will show this by discussing current observational constraints and, in particular, providing forecasts of the capabilities of future CMB and LSS experiments such as CMB-S4 and DESI. In addition, I will provide...
Indirect dark matter (DM) searches are one of the fundamental techniques used to probe the particle nature of DM. Given the increasing interest in the community in non-WIMP scenarios, it is vital to systematically reconsider optimal strategies for observation campaigns of current and future telescopes that cover a large range of DM models and signals. In this endeavour, it is important to...
Template fitting of the gamma-ray sky has been quite successful in both understanding existing sources of emission and discovering new sources, such as the Fermi Bubbles and the GeV excess towards the center of the Milky Way. However, existing models still yield formally poor fits to the data with significant remaining residuals, which makes quantitative comparisons between different models...
Clusters of galaxies should host a significant amount of relativistic cosmic-ray protons accelerated by structure formation shocks during their assembly history, and re-accelerated by turbulence in merging clusters. The quest for the pion-decay emission from hadronic interaction of these relativistic protons with the ambient gas has so far been inconclusive. Nevertheless, gamma-ray...
