We present a multiwavelength study of the 90 brightest cluster galaxies (BCGs) in a sample of galaxy clusters selected via the Sunyaev Zel'dovich effect by the South Pole Telescope, utilizing data from various ground- and space-based facilities. We infer the star-formation rate (SFR) for the BCG in each cluster - based on the UV and IR continuum luminosity, as well as the [O ii]λλ3726,3729 emission line luminosity in cases where spectroscopy is available - and find seven systems with SFR > 100 Mo yr-1. We find that the BCG SFR exceeds 10 Mo yr-1 in 31 of 90 (34%) cases at 0.25 < z < 1.25, compared to ∼1%-5% at z ∼ 0 from the literature. At z 1, this fraction increases to %, implying a steady..
