| Python I, II, and III CMB Anisotropy Measurement Constraints on Open and Flat-Λ CDM Cosmogonies (1999) | |||||||||||||
Abstract | |||||||||||||
| We use Python I, II, and III cosmic microwave background anisotropy data to constrain cosmogonies. We account for the Python beamwidth and calibration uncertainties. We consider open and spatially-flat- cold dark matter cosmogonies, with nonrelativistic-mass density parameter\Omega 0 in the range 0.1--1, baryonic-mass density parameter\Omega B in the range (0.005--0.029)h \Gamma2 , and age of the universe t 0 in the range (10--20) Gyr. Marginalizing over all parameters but\Omega 0 , the combined Python data favors an open (spatially-flat-) model with\Omega 0 ' 0.2 (0.1). At the 2 oe confidence level model normalizations deduced from the combined Python data are mostly consistent with those drawn from the DMR, UCSB South Pole 1994, ARGO, MAX 4 and 5, White Dish, and SuZIE data sets.
