DESCRIPTION:I will present results from the THESAN project\, a suite of la
 rge volume (~100 cMpc)^3 cosmological radiation-hydrodynamic simulations t
 hat simultaneously model the large-scale statistical properties of the int
 ergalactic medium (IGM) during reionization and the resolved characteristi
 cs of the galaxies responsible for it. THESAN offers a unique framework fo
 r high-redshift science by combining state-of-the-art galaxy formation (Il
 lustrisTNG) and dust models with the Arepo-RT solver\, with sufficient res
 olution to enable predictions down to the atomic cooling limit. The simula
 tions have realistic late reionization histories and galaxy properties tha
 t match available constraints\, e.g. halo mass and luminosity relations. I
  will discuss applications from the first set of papers\, including bubble
  size distributions that imprint unique signatures for 21 cm cosmology and
  multi-tracer line intensity mapping\, rapid evolution of the mean free pa
 th of ionizing photons\, emergence of the Lyman-alpha forest\, ionizing es
 cape fractions\, utility of Lyman-alpha emitting galaxies (LAEs) and red d
 amping-wing transmission as probes of reionization. Overall\, THESAN produ
 ces a realistic IGM and galaxy population\, providing a robust framework f
 or future analysis of the high-redshift Universe.
