Title Cosmic downsizing from an X-ray survey of active SDSS galaxies

Description 15 percent of local galaxies in SDSS have optical emission lines indicating an
active nucleus. We propose an XMM survey of a complete sample of z less than
0.05 SDSS galaxies that have these optical AGN signatures. The sample has
measurements of inferred black hole mass, galaxy host type and structure,
stellar mass, star formation rate and environment and provides a unique
opportunity to study black hole accretion in the local universe. In particular,
in this sample most AGN activity is apparent in moderate-mass black holes: we
can measure cosmic downsizing in action at low redshift directly from the
X-ray emission, link [OIII] measurement of accretion to hard-X-ray measurement
across a range of AGN and galaxy types and measure X-ray absorption in a homogeneous sample.

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.
