Radio detection of V407 Cyg - the possible counterpart of the new Fermi LAT Gamma-ray Transient J2102+4542 with the Effelsberg 100-m, OVRO 40-m and IRAM 30-m telescopes
Abstract
Following the Fermi-LAT detection of transient gamma-ray emission near the Galactic Plane, J2102+4542, and its possible association with the symbiotic star and recent nova outburst of V407 Cyg (ATEL #2487, see also CBET #2199, ATEL #2498), we present the first radio detections and a quasi-simultaneous spectrum at the position of V407 Cyg (RA, Dec: 21 02 09.81, +45 46 33.0, J2000). The source was detected with the Effelsberg 100-m, OVRO 40-m and IRAM 30-m telescopes on March 22/23.
