GMRT radio observations of HESS J1640-465
New high resolution and high sensitivity radio observations were conducted with the Giant Metrewave Radio Telescope (GMRT) in the direction of the γ-ray source HESS J1640-465, in positional coincidence with the supernova remnant (SNR) G338.3-0.0. The new images, obtained at 235 MHz and at 610 MHz, a...
