We present CARMA 30 GHz Sunyaev-Zel ’ dovich ( SZ ) observations of five high-redshift ( z \gtrsim 1 ) , infrared-selected galaxy clusters discovered as part of the all-sky Massive and Distant Clusters of WISE Survey ( MaDCoWS ) .
The SZ decrements measured toward these clusters demonstrate that the MaDCoWS selection is discovering evolved , massive galaxy clusters with hot intracluster gas .
Using the SZ scaling relation calibrated with South Pole Telescope clusters at similar masses and redshifts , we find these MaDCoWS clusters have masses in the range M _ { \mbox { \scriptsize 200 } } \approx 2 - 6 \times 10 ^ { 14 } M _ { \odot } .
Three of these are among the most massive clusters found to date at z \gtrsim 1 , demonstrating that MaDCoWS is sensitive to the most massive clusters to at least z = 1.3 .
The added depth of the AllWISE data release will allow all-sky infrared cluster detection to z \approx 1.5 and beyond .
