| Description | We propose to investigate the spectrum of X-ray emission from the edge of the recently discovered Galactic gamma-ray features known as the Fermi bubbles. The bubbles extend 50 degrees above and below the Galactic center, with a width of about 40 degrees in longitude. These structures could result from a large-scale accretion driven outflow on the central black hole, or winds from a nuclear starburst. ROSAT X-ray maps (bands R6 and R7) show closely related features with a relatively hard spectrum. This spectrum may be thermal bremsstrahlung emission from T~10^7 K gas, or may contain significant line emission. The proposed observations can distinguish between these two alternatives. |

| 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. |
