Maps of the large-scale structure of galaxies (purple) and gas
temperature distributions within the cluster (pink). Brighter pink
indicates higher temperature. The filamentary structure is found
outside the cluster in the top-left direction, in contact with the
hotter gas realm. The other fields in which there are few galaxies
(black) contact the cooler realm. The white line represents 10 million
light-years.
