The Origin of High Energy Emission in the Young Radio Source PKS 1718-649
Małgosia Sobolewska, Giulia Migliori, Luisa Ostorero +4
We present a model for the broadband radio-to--ray spectral energy distribution of the compact radio source, PKS 1718-649. Because of its young age (100 years) and proximity ($z…
