Abstract:
We present radio results fromshort e-EVN (EuropeanVLBI network) observations of the counterpart to IGR J20187+4041, a hard X-ray source projected against the γ Cygni supernova remnant (SNR). The brightest unidentified EGRET source 3EG J2020+4017 is also located in the γ Cygni region, though its relation to IGR J20187+4041 has not been well established yet. The e-EVN observations were carried out following the AGILE detection of gamma-ray flaring activity in the region. Our observations show that the radio counterpart to the IGR source has a compact structure on the ∼ 10 mas scales that could be related to a compact object, but no radio flaring activity has been observed. e-VLBI*is a technique which makes it possible to image the structure of radio sources at the highest angular resolution on a very short timescale. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
