| Abstract | GSN 069 is the first galactic nucleus where quasi-periodic eruptions (QPEs) havebeen identified. Recent analysis of its long-term X-ray evolution, coupled withlong XMM-Newton exposures, reveals that QPEs disappear above a bolometricluminosity threshold of 3.5e43 erg/s of the quiescent emission. If confirmed,this observational fact is highly constraining for QPE models. We request oneTOO observation of GSN 069 to confirm the absence of QPEs above threshold and,were they instead be detected, to characterise their properties at so-farunexplored high luminosity levels. We propose a set of joint Swift monitoringobservations that will be used to trigger the proposed XMM-Newton TOO. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
