High-velocity H I jet-like feature towards the SNR candidate G351.7-1.2.

Abstract (from CDS):

We present the H I 21 cm spectral line and continuum observations of the Galactic supernova remnant (SNR) candidate G351.7-1.2 using the upgraded Giant Metrewave Radio Telescope. Strong absorption features are observed towards the H II regions in the star-forming complex associated with G351.7-1.2. Along with H I emission towards the outer periphery of the SNR shell, we distinguish a high-velocity jet-like feature in the velocity range +40 to +52 km s–1 in H I. This unusual and highly collimated feature, with a projected length of ∼7 pc and an opening angle of 14.4°, is located towards the interior of the radio shell. This is the first report of a well collimated H I jet-like emission. The peculiar location and the detection of a γ-ray source towards the central peak of this H I jet suggests its plausible association with the SNR candidate.
