Lyman Page 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, helping researchers understand how the universe began and how the observed structure, at sizes ranging from galaxies to super clusters of galaxies, came to be.

Page has measured the cosmic microwave background (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. Page is one of the original co-investigators on the WMAP satellite and was the founding director of the ACT project.
