资源简介:

We propose to carry out a simultaneous fit of Xray images and GBT/MUSTANG2 SZEmeasurements for three closestpair merging clusters discovered by the SubaruHSC Survey. The high angular resolution of 9 arcsec FWHM of MUSTANG2 allows usto map out the Compton y parameter. A combination of high angular resolution SZEand Xray imaging enables us to resolve the degeneracy between the numberdensity and temperature in the y parameter and perform a spatiallyresolvedmulticomponent analysis to understand complex gas distributions in mergingclusters. The HSC survey efficiently discovers ongoing mergers and measures WLmasses of the main and sub halos. Multiwavelength Xray, SZE, and WL studieswill provide us with a comprehensive picture of merger boosts of gas properties. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
