| Description | The Gaia Gravitational Lenses working group (GraL) has dramatically increased the number of known lenses in the past three years, particularly doubly-imaged quasars. X-ray observations of these rare systems provide a powerful tool for a range of studies, from inferring the structure near the event horizons of supermassive black holes to measuring black hole spins at cosmological distances. We propose a snapshot survey of the brightest newly identified doubles to establish a baseline sample for deeper observations and monitoring. |

| 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. |
