Python I, II, and III CMB Anisotropy Measurement Constraints on Open and Flat-Lambda CDM Cosmogonies

Graca Rocha, Radoslaw Stompor, Ken Ganga +4

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 op…

Detection of Cosmic Microwave Background Structure in a Second Field with the Cosmic Anisotropy Telescope

Joanne C. Baker, Keith Grainge, M. P. Hobson +9

We describe observations at frequencies near 15 GHz of the second 2x2 degree field imaged with the Cambridge Cosmic Anisotropy Telescope (CAT). After the removal of discrete radio…

CMB Anisotropy Constraints on Open and Flat-Lambda CDM Cosmogonies from UCSB South Pole, ARGO, MAX, White Dish, and SuZIE Data

Bharat Ratra, Radoslaw Stompor, Ken Ganga +3

We use combinations of ten small-scale cosmic microwave background anisotropy data sets from the UCSB South Pole 1994, ARGO, MAX 4 and 5, White Dish and SuZIE experiments to constr…
