Resumen:
Long gamma-ray bursts are likely the result of the collapse of very massive stars into black holes. These events are expected to produce high-energy neutrinos through photomeson production. Such neutrinos can escape from the source and travel up to the Earth. In the case of Population III progenitors for gamma-ray bursts, the neutrinos can be the only source of information of the first stars formed in the universe. The expected signal is rather weak, but we propose that gravitational lensing by nearby supermassive black holes can offer a natural tool to enhance and give a chance to detect neutrinos from the re-ionization era of the universe with current instrumentation.
