The Massive and Distant Clusters of WISE Survey (MaDCoWS) provides a catalogof high-redshift ($0.7\lesssim z\lesssim 1.5$) infrared-selected galaxyclusters. However, the verification of the ionized intracluster medium,indicative of a collapsed and nearly virialized system, is made challenging bythe high redshifts of the sample members. The main goal of this work is to testthe capabilities of the Atacama Compact Array (ACA; also known as the MoritaArray) Band 3 observations, centered at about 97.5 GHz, to provide robustvalidation of cluster detections via the thermal Sunyaev-Zeldovich (SZ) effect.Using a pilot sample that comprises ten MaDCoWS galaxy clusters, accessible toACA and representative of the median sample richness, we infer the masses ofthe selected galaxy clusters and respective detection significance by means ofa Bayesian analysis of the interferometric data. Our test of the "Verificationwith the ACA - Localization and Cluster Analysis" (VACA LoCA) programdemonstrates that the ACA can robustly confirm the presence of the virializedintracluster medium in galaxy clusters previously identified in full-skysurveys. In particular, we obtain a significant detection of the SZ effect forseven out of the ten VACA LoCA clusters. We note that this result isindependent of the assumed pressure profile. However, the limited angulardynamic range of the ACA in Band 3 alone, short observational integrationtimes, and possible contamination from unresolved sources limit the detailedcharacterization of the cluster properties and the inference of the clustermasses within scales appropriate for the robust calibration of mass-richnessscaling relations.
