Abstract | We request a quasi-simultaneous XMM-Newton and HST/STIS observation of GSN 069,a high-Eddington ratio true/unabsorbed Seyfert 2 galaxy candidate withultra-soft X-ray spectrum. From our study of previous X-ray/optical spectra andof UV photometric data, we infer that the lack of BLR in this peculiar objectmay be attributed to ether (i) the lack of hard X-ray emission or (ii) anevolutionary scenario in which the BLR are just forming. Recent Swift pointingshave revealed the emergence of hard X-rays in GSN 069, making the proposedobservation highly timely. GSN 069 may represent a true Rosetta stone with whichto follow the formation and early evolution of the X-ray corona and to study theconnection between X-rays and the BLR/disc-wind system. |

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. |
