| Abstract | We have recently reported on the discovery of a new X-ray variability patternfrom the nucleus of the galaxy GSN~069, dubbed as Quasi-Periodic Eruptions, orQPEs (Miniutti et al. 2019, Nature, 573, 381). We propose here for furtherXMM-Newton observations to better characterize this newly-discovered variabilitypattern. Ideally, our observations will be complemented with 2 HST orbits withthe goals of: i) deriving the optical to X-ray SED of GSN~069; ii) search forpossible blue point sources other than the galactic nucleus in comparison withour Chandra data; iii) study the morphology of the poorly known host galaxy; iv)study the spatially-resolved structure of the narrow-line-region in O~III. |

| 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. |
