| Abstract | We propose to carry out a simultaneous fit of X-ray images and GBT/MUSTANG-2 SZEmeasurements for three closest-pair merging clusters discovered by the SubaruHSC Survey. The high angular resolution of 9 arcsec FWHM of MUSTANG-2 allows usto map out the Compton y parameter. A combination of high angular resolution SZEand X-ray imaging enables us to resolve the degeneracy between the numberdensity and temperature in the y parameter and perform a spatially-resolvedmulti-component analysis to understand complex gas distributions in mergingclusters. The HSC survey efficiently discovers on-going mergers and measures WLmasses of the main- and sub- halos. Multi-wavelength X-ray, SZE, and WL studieswill provide us with a comprehensive picture of merger boosts of gas properties. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
