Abstract

We report 31GHz CARMA observations of IDCSJ1426.5+3508, an infrared-selected galaxy cluster at z = 1.75. A Sunyaev-Zel'dovich (SZ) decrement is detected toward this cluster, indicating a total mass of M _{200, m} = (4.3 ± 1.1) × 10¹⁴ M _⊙ in agreement with the approximate X-ray mass of 5 × 10¹⁴ M_ȯ. IDCSJ1426.5+3508 is by far the most distant cluster yet detected via the SZ effect, and the most massive z ≥ 1.4 galaxy cluster found to date. Despite the mere 1% probability of finding it in the 8.82deg² IRAC Distant Cluster Survey, IDCSJ1426.5+3508 is not completely unexpected in ΛCDM once the area of large, existing surveys is considered. IDCSJ1426.5+3508 is, however, among the rarest, most extreme clusters ever discovered and indeed is an evolutionary precursor to the most massive known clusters at all redshifts. We discuss how imminent, highly sensitive SZ experiments will complement infrared techniques for statistical studies of the formation of the most massive galaxy clusters in the z > 1.5 universe, including potential precursors to IDCSJ1426.5+3508.
