摘要：

Arcminute Microkelvin Imager（AMI）在2008年至2011年期间通过Sunyaev-Zel'dovich效应对星系团进行了盲测。第一个检测，被称为AMI-CL J 0300 +2613，已重新观察与AMI配备了一个新的数字相关器，具有高动态范围。新的AMI数据和最近的高分辨率亚毫米和红外地图的组合现在显示，该特征实际上是一个正尘埃相关的银河系发射环，这可能是异常微波发射（AME）。如果是这样的话，这是第一次在弧分尺度上完全盲检测AME。

英文摘要：

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.
