Title: Searching for the first stars ``around the clock''

Abstract: Gamma-ray bursts are produced by the explosion of 20-100 solar mass stars. They have been detected up to redshift $zsim8-9$ and their optical/NIR emission is bright enough to provide high signal to noise ratio spectra. Unfortunately, the rarity of such high-$z$ events requires every possible effort to promptly observe as many GRB as possible. In this proposal we request to utilize the LCO network of 1m and 2m telescopes in order to expand our sky coverage and identify possible high-$z$ candidates to be subsequently observed with our 4-8m NIR dedicated facilities. We expect to increase by 25% our sample of $zsim6$ GRBs and to provide for the first time a high-resolution spectrum of a $zgtrsim7$ GRB: this data will shed light on the chemical enrichment of the Universe at such early stage as well as provide constrain on reionization. Furthermore, identifying such objects will provide invaluable resources for future NIR observation with the James Webb Space Telescope and Thirty meter facilities.
