A Canadian and American team of Astronomers have used the 305-m wide Arecibo radio dish, the world's largest and most sensitive radio telescope, to uncover a dozen new super-fast-spinning pulsars. The team directed their search for these rare and exotic stars by pointing the Arecibo radio telescope towards massive star clusters, called Globular Clusters, orbiting our Milky Way galaxy. ... One of the most exotic residents in the Globular cluster system are the millisecond pulsars. ...

This is a cosmic microwave background (CMB) telelescope with a difference, in that it is designed to survey the sky looking for galaxy clusters by means of the ?shadows? they cast against the CMB. This shadowing, the so-called SZ effect, is a remarkable phenomenon because it is independent of redshift, allowing AMI to find clusters which are so far away that their own emission would be too faint to detect ? ...
