Clusters of Galaxies at High Redshift: The LMT/GTM Perspective

Abstract

The lack of reliable cluster samples at intermediate and high redshift has motivated many optical/infrared and X-ray cluster searches. The motivation of such searches is well justified: the abundance of massive collapsed regions gives a direct constraint on Omega(matter). Alternatively, the Sunyaev-Zeldovich effect (SZE) offers a robust method for the detection of clusters which is, almost, independent of redshift. In this paper we comment on the possibility of mapping the SZE at high resolution in the millimeter regime using the Large Millimeter Telescope/Gran Telescopio Milimetrico (LMT/GTM) and the bolometer array BOLOCAM. The construction of the LMT/GTM facility is underway atop Cerro La Negra (latitude=18deg 59min; height=4600 m) in Mexico.
