Description | PV- X-rays from sources outside the field of view can enter the EPIC field of view. The X-ray baffles in front still leak at some level out to off-axis angles of about 1.5 degrees. The angular dependence and the level have been measured on ground but need to be verified in orbit by one pointing with the source on-axis and four additional pointings with the source offset by 70 arcmin at four different azimuth angles. The source should be sufficiently bright, stable in time and should show emission lines to ease the analysis of the spectral dependence. A moderate spatial extent but less than the EPIC field of view is advantageous. Such a source is the Tycho SNR. This proposal is for the on-axis position of the programme. |

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. |
