Gamma-ray young radio source
We propose EVN observations in L and C bands of the steep spectrum radio source PKS 1007+142. This source has been recently discovered to emit gamma rays, becoming the third case of a young radio galaxy detected at high energy. Although its gamma-ray emission does not show significant variability, the gamma-ray luminosity is relatively high, making its origin, either from beamed jet or from the lobes, still puzzling. Its radio structure from MERLIN observations, with the source core still unidentified, cannot help constrain the nature of the gamma-ray emission. Deep dual-frequency EVN (plus e-MERLIN at 5 GHz) observations are necessary for determining the radio structure by unveiling the core and determine the jet orientation on pc-scales. The source structure and jet orientation will provide crucial information for constraining the origin and the physical mechanisms of the gamma-ray emission.
