Galaxy Cluster Gas Creates Hole in Microwave Background
Galaxy clusters contain very hot gas, which can interact with the Cosmic Microwave Background (CMB). This interaction, called the Sunyaev-Zel'dovich effect, up-scatters CMB photons to higher energies. This creates 'holes' in CMB maps where the clusters are located. Astronomers use this effect to study galaxy clusters and the early universe.
