    • Restarting activity in the nucleus of PBC J2333.9-2343 An extreme case of jet realignment 

      Hernández-García, L.; Panessa, F.; Giroletti, M.; Ghisellini, G.; Bassani, L.; Masetti, N.; Pović, M.; Bazzano, A.; Ubertini, P.; Malizia, A.; Chavushyan, V. (EDP Sciences, 2017-07)
      Context. The giant radio galaxy PBC J2333.9-2343 shows different characteristics at different wavebands that are difficult to explain within the actual generic schemes of unification of active galactic nuclei (AGN). It is ...
    • SCORPIO - II. Spectral indices of weak Galactic radio sources 

      Cavallaro, F.; Trigilio, C.; Umana, G.; Franzen, T.M.O.; Norris, R.P.; Leto, P.; Ingallinera, A.; Buemi, C.S.; Marvil, J.; Agliozzo, C.; Bufano, F.; Cerrigone, L.; Riggi, S. (Oxford University Press, 2018-01)
      In the next few years the classification of radio sources observed by the large surveys will be a challenging problem and spectral index is a powerful tool for addressing it. Here we present an algorithm to estimate the ...
