GMRT High Resolution Southern Sky (GHRSS) survey for pulsars and transients with the GMRT scans the southern sky,
with comarable of higher sensitivities than any other existing or ongoing low-frequency surveys. This survey is conducted
in two phases, phase-1 at 322 MHz with the 32 MHz legacy GMRT system (discovered 13 pulsars) and phase-2 at 400 MHz with 200
MHz uGMRT system(14 discoveries and counting). When complete, the survey will cover the entire sky southern sky up to declenation of -20°.
GHRSS discoveries include the first MSP and first RRATs discovered by the GMRT.
Data taking began in 2014 and is phase-2 expected to be completed in 2022.
Survey analysis is done in Hydrus cluster in University of Manchester (for phase-1 of the survey) and NCRA HPC (for phase-1 and phase-2) with
PRESTO based search pipeline.
To date there are 31 GHRSS discoveries among which there are 2 MSPs, 2 mildly recycled pulsars and 3 RRATs.
