Cosmology is currently in a period of rapid development. During the past decade, increasing observational evidence has led to the establishment of the LCDM model. Despite its success, the latter has recently been challenged by several tensions. The combination of galaxy surveys and CMB lensing is a powerful probe of the large-scale structure and a key tool for testing the standard cosmological...
The W28 supernova remnant is a promising site for studying the acceleration and propagation of Galactic cosmic rays. Its proximity to dense molecular clouds provides a natural environment for cosmic-ray interactions and γ-ray production. We use data from the High-Altitude Water Cherenkov (HAWC) Observatory to investigate the very-high-energy (VHE; >100 GeV) γ-ray emission from the W28 region....
