Abstract

We present follow-up observations of two galaxy clusters detected blindly via the Sunyaev- Zel'dovich (SZ) effect and released in the Planck Early Release Compact Source Catalogue. We use the Arcminute Microkelvin Imager, a dual-array 14-18 GHz radio interferometer. After radio source subtraction, we find a SZ decrement of integrated flux density -1.08 ± 0.10 mJy towards PLCKESZ G121.11+57.01, and improve the position measurement of the cluster, finding the centre to be RA 12h59m36.s4, Dec +60°04'46."8, to an accuracy of 20 arcsec. The region of PLCKESZ G115.71+17.52 contains strong extended emission, so we are unable to confirm the presence of this cluster via the SZ effect. © 2011 The Authors Monthly Notices of the Royal Astronomical Society. © 2011 RAS.
