DOI: 10.1038/s41550-023-02168-6
Abstract: Cosmic rays (CR) are energetic nuclei that permeate the entire Galactic disk. Their existence requires the presence of powerful particle accelerators. While Galactic supernova explosions may supply the required energy, there is growing evidence that… read more here.

DOI: 10.1093/mnras/staa444
Abstract: The coalescence of supermassive black holes (SMBHs) should generate the strongest sources of gravitational waves (GWs) in the Universe. However, the dynamics of their coalescence is the subject of much debate. In this study, we… read more here.
