Black holes can tidally disrupt nearby stars, resulting in luminous emissions that last for a few weeks to months. This high-energy transient phenomenon is known as tidal disruption event (TDE) and is detected through multiwavelength observations. TDEs have been thoroughly examined within the local universe using diverse observations and theoretical frameworks. However, the study of TDEs at high redshifts has been relatively scarce. Latest telescopes with advanced high-resolution, wide-field surveys such as JWST, LSST, and upcoming Nancy Grace Roman Space Telescope and ULTRASAT are set to revolutionize our understanding of TDEs at high redshifts. The main focus of this talk involves exploring the early universe through TDEs of the first stars, investigating TDE rates, and analyzing their correlation with various host galaxy properties, as well as the redshift evolution of these correlations using theoretical models and high-resolution cosmological simulations. Finally, I will discuss the key findings from our recent work that shows an enhanced theoretical TDE rate at high redshift and the potential for observing intermediate-mass black holes with LSST, Roman, and ULTRASAT.
