The upgradation includes better frequency coverage, larger instantaneous bandwidth, improved receiver system, better capabilities of the back-end correlator with more spectral channels and real time flagging option, and matching improvements in other supporting systems. The improved sensitivity, frequency coverage and spectral resolution, much of which has already been implemented, make uGMRT a key low frequency facility for the coming years. With the improved capabilities, it is now possible to use uGMRT more effectively for both continuum and spectral line observations. For example, better frequency coverage opens up the possibility of exploring larger redshift range as well as more spectral line transitions, whereas larger instantaneous bandwidth makes it an ideal instrument for large blind spectral surveys. Furthermore, the higher spectral resolution not only gives us a detailed view of the sources, but also allows for better removal of the interference. In this presentation, I will talk about the potential of the uGMRT for spectral line observations of the local and the high redshift universe. I will present the current status and some of the early results from recent observations. With such unique capabilities, uGMRT is expected to be a proficient pathfinder of the Square Kilometre Array. |
