Abstract : Spiral galaxies like our own Milky Way maintains a constant star formation in the disk through continuous replenishment of gas supply from infall and accretion. The ongoing star formation in a spiral galaxy can however be quenched due to internal and external processes. AGN feedback (internal) and ram pressure stripping (external) are the two efficient processes that are hypothesised to be responsible for star formation quenching in spiral galaxies. This talk presents an ongoing ultraviolet survey of spiral galaxies in dense environments using ASTROSAT/UVIT where we see evidences of AGN feedback and ram pressure stripping simultaneously quenching star formation in a spiral galaxy.
