Cosmic Microwave Background (CMB) and Large Scale Structure (LSS) surveys have played a crucial role in developing the standard model of cosmology. The upcoming missions are going to bring up a large data volume from a deeper redshift range. In my talk, the speaker will introduce a few new frontiers in cosmology which will open-up from the upcoming CMB, LSS and gravitational wave (GW) missions which will be capable to serve wider science goals. In the first part of the talk, he will discuss the cross-correlation technique between redshift unknown supernovae and binary black holes with the cosmic density field to make a precise measurement of the properties of dark energy and other cosmological parameters. This technique will be a very powerful method for the upcoming LSS and GW surveys to make an accurate measurement of the cosmological parameters. In the latter part of the talk, he will discuss the imprints of cosmological perturbations on the GW signal from compact objects and will introduce new cosmological probes to measure these imprints from ground-based and space-based GW experiments. These new probes are going to open an era of multi-messenger cosmology and will be capable to explore several aspects of fundamental physics.
