| Description | Swift observations of gamma-ray bursts recently highlighted the existence of rare high-energy transients, characterized by extremely long durations (from hours to days). The origin of these enigmatic events, dubbed ultralong GRBs, remains uncertain with the prime model being the collapse of a low-metallicity Blue Supergiant star. In this scenario ultralong GRBs could represent the local analogues of pop III GRBs, thus providing a nearby laboratory to investigate primordial star explosions. Here we propose a ToO program to observe a newly discovered ultralong GRB. The requested X-ray observations will be complemented by an extensive follow-up campaign through our on-going radio, optical, and IR programs. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
