Title X-raying strong gravitational lenses: dark halos and the environment


DOI 10.5270/esa-j52iyra
Author Prof Tommaso Treu
Description The SLACS collaboration measured the dark matter halos of elliptical galaxies on scales from 1 to 100 kpc, using a combination of lensing (strong and weak) and stellar dynamics. This provides new tests of the standard cosmological models at galaxy-group scales. However, lensing can only measure the total projected mass along the line of sight, and therefore can be affected by large-scale structures in projection. We propose to observe a complete subset of SLACS lenses to identify nearby groups and clusters, determine their location, temperature, and mass and study the dependency of halo profiles on the local environment, expected because of tidal interactions. The selected low redshift (average 0.13) lens sample is ideal for an X-ray investigation at galaxy-group scales.

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.
