cold spot

(CMB cold spot, WMAP cold spot)
(unusually colder spot in the CMB)

A cold spot (or cosmic microwave background cold spot or WMAP cold spot) is an area where the CMB indicates a slightly lower black body temperature than expected, a difference on the order of 70 millionths of a Kelvin degree. The CMB black body temperature has a random distribution around a value near 2.7K except for these areas. Some research has suggested they correspond to voids.
