DZIB, Sergio; RODRIGUEZ, Luis F. e LOINARD, Laurent. A Compact Radio Counterpart to the Energetic X-ray Pulsar Associated with the TeV Gamma-Ray Source J1813-178. Rev. mex. astron. astrofis [online]. 2010, vol.46, n.1, pp. 153-157. ISSN 0185-1101.
We report the detection of a time-variable, compact radio source coincident with CXOU J181335.1-174957, the X-ray pulsar near the center of the young radio supernova remnant G12.82-0.02, which overlaps the compact TeV source HESS J1813-178. The compact radio source, named VLA J181335.1-174957, was detected in 4.86 GHz VLA observations made in 2006. New VLA observations made in 2009 do not detect the source at a level 1.9±0.7 times (2.8σ) lower than that of 2006. We suggest that VLA J181335.1-174957 may be related to one of the recently detected classes of variable radio pulsars but cannot reach a firmer conclusion.
