Issue Date: | 2018 | Journal: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Number: | 89 | First Page: | 148 | Abstract: | The Infra-Red Telescope (IRT) on board THESEUS will play a key role in identifying and characterizing moderate to high redshift Gamma-Ray Bursts afterglows. The IRT enables the on board GRB autonomous redshift determination, thus allowing the ground based telescopes to be triggered on a redshift pre-selected sample and finally fulfilling the cosmological goals of the mission. The IRT will be composed by a primary mirror of 0.7 m of diameter coupled to a single camera in a Cassegrain design. It will work in the 0.7-1.8 mu m wavelength range, and will provide a 10×10 arc min imaging field of view with sub-arc second localization capabilities, and, at the same time, a 5×5 arc min field of view with moderate (R up to ∼500) spectroscopic capabilities. Its sensitivity, mainly limited by the satellite jitter, is adapted to detect all the GRBs, localized by the THESEUS SXI/XGIS instruments, and to acquire spectra for the majority of them. | URI: | http://hdl.handle.net/20.500.12386/27688 | URL: | http://sait.oat.ts.astro.it/MSAIt890218/index.html | ISSN: | 0037-8720 | Bibcode ADS: | 2018MmSAI..89..148G | Fulltext: | open |
