Description | Double-source-plane (DSP) gravitational lensing systems offer a variety of cosmological/astrophysical information, although they are rare. We discovered the DSP lens Eye of Horus in the Subaru HSC survey Program, and our follow-up spectroscopy makes this system the only DSP lens to date with spectroscopic confirmation of both source redshifts. Recently, we have found two massive clusters in the lens plane, likely affecting the lens potential. In order to disentangle the complex environment to exploit this unique system, we propose a 40 ksec XMM observation of the system, which will allow us to determine accurately the clusters. X-ray centroids, potential shapes, and individual gas thermodynamic properties, providing valuable priors for detailed lens modeling. |

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. |
