GMRT observations of SNR G15.4+0.1/HESS J1818-154

We report here on the first dedicated simultaneous imaging and pulsar observations towards the supernova remnant (SNR) G15.4+0.1, the possible counterpart of the very high energy (VHE) source HESS J1818-154. The observations were carried out using the Giant Metrewave Radio Telescope (GMRT) at 610 an...
