Abstract
The Arcminute Microkelvin Imager (AMI) carried out a blind survey for galaxy
clusters via their Sunyaev-Zel'dovich effect decrements between 2008 and 2011.
The first detection, known as AMI-CL J0300+2613, has been reobserved with AMI
equipped with a new digital correlator with high dynamic range. The combination
of the new AMI data and more recent high-resolution sub-mm and infra-red maps
now shows the feature in fact to be a ring of positive dust-correlated Galactic
emission, which is likely to be anomalous microwave emission (AME). If so, this
is the first completely blind detection of AME at arcminute scales.
