Full-sky projections of the CR electron component. Upper panel: Energy density of electrons in the range E ∈ [5 − 500] MeV as the mean along the line of sight in a radius range r = 5 − 300 Mpc. This traces the injected energy density of the CR electrons with the longest lifetimes. Circles indicate the projected r_vir of the cross-identified clusters (see Hernández-Martínez et al. 2024). Lower panel: CR electrons with energies E_CR, e > 1 GeV integrated along the line of sight in a radius range r = 5 − 300 Mpc. The short cooling times of these electrons lead to this map tracing recent injection events.
