DESCRIPTION:Speakers: Rudrani Kar Chowdhury (Tata Institute of Fundamental
  research (TIFR))\n\nAbstractBlack holes can tidally disrupt nearby stars\
 , resulting in luminous emissions that last for a few weeks to months. Thi
 s high-energy transient phenomenon is known as tidal disruption event (TDE
 ) and is detected through multiwavelength observations. TDEs have been tho
 roughly 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 Sp
 ace Telescope and ULTRASAT are set to revolutionize our understanding of T
 DEs 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 mod
 els 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-mas
 s black holes with LSST\, Roman\, and ULTRASAT. \n\nhttps://events.iiap.r
