: a new observable for photon-hadron discrimination in hybrid air shower events
M. Niechciol, M. Risse, P. Ruehl +3
To search for ultra-high-energy photons in primary cosmic rays, air shower observables are needed that allow a good separation between primary photons and primary hadrons. We prese…

Unusual radio variability in the BL Lac object 0235+164
A. Kraus, A. Quirrenbach, A. P. Lobanov +11
We present radio observations at three frequencies and contemporaneous optical monitoring of the peculiar BL Lac object AO 0235+164. During a three-week campaign with the VLA we ob…
