Description | We propose four, logarithmically spaced, 50 ks XMM-Newton observations of the Seyfert galaxy NGC1068, the archetypal and one of the brightest Compton-thick Seyfert 2. This source is likely accreting at a high rate, so it is expected to be intrinsically highly variable. Previous works have indeed claimed both spectral and continuum variability, although between observations performed with different spectrometers and satellites. The four proposed observations will permit to search for variations of the reflected components on time scales spanning from a week to half a year and, when compared with previous XMM-Newton observations, up to several years. This program will allow us to both unambiguously confirm previous claims of such variations and tightly constrain |

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. |
