Cosmologist Lyman Page, with students and collaborators, measures the spatial variations of temperature and polarization in the cosmic microwave background (CMB).

The CMB, which pervades the universe, is the thermal afterglow of the big bang. Detailed knowledge of the magnitude and pattern of the fluctuations in temperature and polarization reveals information about the basic parameters that describe the universe. This helps researchers understand how the universe began and how the observed structure, at sizes ranging from galaxies to superclusters of galaxies, came to be.

Page has measured the CMB from ground-based, balloon-borne and satellite platforms with HEMT amplifiers, SIS mixers and bolometers. He has been a principal investigator or co-investigator on the FIRS, Saskatoon, MSAM, QMAP, TOCO/MAT, MINT and ABS experiments. He is one of the original co-investigators on the WMAP satellite and was founding director of the ACT project.
