Contribution of Flares from Tidal Disruption of Stars to high-redshift
  AGN
  We explore the contributions of Tidal Disruption Events (TDEs) to the flares
in Active Galactic Nuclei (AGN) at high redshifts. Using the latest data
available from X-ray and optical observations of high-redshift galaxies, in
combination with the evolution of their central supermassive black holes, we
calculate the contribution of TDE to AGNs as a function of their luminosities.
We find that at low redshifts ($z < 1$), a few percent of all AGN with
bolometric luminosities $L_{\rm Bol} \lesssim 10^{44}$ erg s$^{-1}$ may be
attributable to possible TDEs. However, this fraction can significantly
increase at earlier cosmic times, including up to several tens of percent of
the population of AGN at $z \gtrsim 3$. TDEs may comprise a significant
fraction of the Compton-Thick (CT) AGN population at $z \gtrsim 3$. The above
findings motivate further calibration with upcoming X-ray missions and
spectroscopic surveys targeting TDE-AGN.
