z>1 galaxy clusters from IRAC Shallow Survey

We have identified 335 galaxy cluster and group candidates, 106 of which are at z>1, using a 4.5um-selected sample of objects from a 7.25deg^2^ region in the Spitzer Infrared...我们基于斯皮策红外（Spitzer Infrared）巡天中7.25平方度天区里通过4.5微米选源得到的天体样本，共筛选出335个星系团与星系群候选体，其中106个的红移z大于1。
