Description The densest and closest absorbers of the soft X-ray background (SXRB) in the
Milky Way are Bok globules, located just outside the Local Bubble in the Pipe
Nebula at a distance of 125pc. With column densities of up to log(NH)virgul23, they
are ideal targets for shadowing the SXRB in the energy range 0.3 - 2 keV, thus
giving important information on the spatial and spectral variation of the
foreground X-ray intensity on small scales. We propose Barnard 59 due to an
extinction gradient of A_Vvirgul50 mag and the Fest 1-457 region due to strong small
scale NH-variations for a detailed spectral study with XMM-Newton. Together with
already existing XMM data of Barnard 68, this will allow to determine the
ionization structure of the Local and Loop I superbubbles.

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.
