Implications of MAX for CDM

Abstract

We analyze the Gamma Ursae Minoris (GUM) and Mu Pegasii (MuP) scans of the Millimeter-wave Anisotropy eXperiment in the context of cold dark matter (CDM) models of structure formation, paying particular attention to the two-dimensional nature of the GUM scan. If all of the structure in the (foreground subtracted) data is attributed to cosmic microwave background anisotropy, then there is a detection in each scan. For a standard CDM model, the amplitudes of the signals are individually compatible with the COsmic Background Explorer measurement, but marginally inconsistent with each other.
