The first year data from the Wilkinson Microwave Anisotropy Probe are used toplace stringent constraints on the topology of the Universe. We search forpairs of circles on the sky with similar temperature patterns along eachcircle. We restrict the search to back-to-back circle pairs, and to nearlyback-to-back circle pairs, as this covers the majority of the topologies thatone might hope to detect in a nearly flat universe. We do not find any matchedcircles with radius greater than 25 degrees. For a wide class of models, thenon-detection rules out the possibility that we live in a universe withtopology scale smaller than 24 Gpc.Comment: Submitted to PR
