Deflection of ultra-high energy heavy nuclei in the Galactic magnetic field

EPJ Web of Conferences, 2013
In this work, we investigate the impacts a potential shift towards a heavy composition at the end of the cosmic ray (CR) spectrum would have on the future data [1, 2].

Spatial Distribution of Intracluster Light versus Dark Matter in Horizon Run 5

The Astrophysical Journal
One intriguing approach for studying the dynamical evolution of galaxy clusters is to compare the spatial distributions among various components such as dark matter, member galaxies, gas, and intracluster light (ICL).
