DESCRIPTION:The Transient High-Energy Sky and Early Universe Surveyor (THE
 SEUS) is a mission concept developed by a large European collaboration und
 er study by ESA since 2018 and currently one of the three candidate M7 mis
 sion for a launch in the late '30s. THESEUS aims at fully exploiting Gamma
 -Ray Bursts for investigating the Cosmic Dawn and as key phenomena for mul
 ti-messenger astrophysics. By providing an unprecedented combination of X-
 /gamma-ray monitors\, on-board IR telescope and spacecraft autonomous fast
  slewing capabilities\, THESEUS will be a wonderful machine for the detect
 ion\, multi-wavelength characterization and redshift measurement of any ki
 nd of GRBs and many classes of X-ray transients\, including high-redshift 
 GRBs for cosmology (primordial low-mass/luminosity galaxies\, first stars\
 , cosmic re-ionization) and electromagnetic counterparts to sources of gra
 vitational waves. Moreover\, THESEUS will enable extreme and fundamental p
 hysics through unprecedented breakthrough measurements of GRB prompt and a
 fterglow emission\, as well as the detection and multi-eavelength characte
 rization of many classes of high-energy transients. In all thses respects\
 , THESEUS will thus provide an ideal synergy with the very large astronomi
 cal facilitiesof the future working in the e.m. (e.g.\, ELT\, CTA\, SKA\, 
 Athena) and multi-messenger (e.g.\, Einstein Telescope\, Cosmic Explorer\,
  km3NET).\nAbout the speaker: Dr. Lorenzo Amati is a high-energy astrophys
 icist who famously discovered the "Amati relation\," a correlation between
  the spectral peak photon energy and the total radiated energy of gamma-ra
 y bursts\, which has significant implications for understanding GRB physic
 s and their potential use in cosmology. Since 2017\, Dr. Amati is the Dire
 ctor of Research at the Osservatorio di Astrofisica e Scienza dello Spazio
  (OAS) of INAF in Bologna and since August 2024\, he is the Director of IN
 AF - OAS. Dr. Amati is the Mission Principal Investigator and Lead Scienti
 st for the THESEUS mission\, currently under study by the European Space A
 gency (ESA)\,  aimed at investigating the early Universe and revolutioniz
 ing multi-messenger time domain astrophysics through the study of GRBs and
  other transient phenomena.\nIn the OKC: Nov 10-12 2025\, A5 corridor (KTH
