Abstract

The latest enhancement to the GMRT’s transient science capability is the SPOTLIGHT project, designed to detect Fast Radio Bursts (FRBs) in real-time. This is achieved by forming 2000 post-correlation (PC) beams across the sky while piggybacking on regular GMRT observations over a frequency range from 300 MHz to 1460 MHz. In addition to real-time FRB detection, SPOTLIGHT includes a quasi-real-time pulsar search using 10% of the full field-of-view. The acquired data will undergo weekly processing using a Fourier Domain Acceleration Search pipeline, aiming to discover new pulsars from SPOTLIGHT observations. In this presentation, I will highlight the development and optimisation of the multi-GPU pulsar search pipeline designed for SPOTLIGHT. Additionally, I will discuss the key scientific goals of the pulsar search component, including the expected pulsar yield and the broader astrophysical implications of this project. Enabling commensal pulsar searches on GMRT, serving as both a science initiative and a technology demonstrator.
