ARGO CMB anisotropy measurement constraints on open and flat-Lambda cold dark matter cosmogonies

We use data from the ARGO cosmic microwave background (CMB) anisotropy expe riment to constrain cosmogonies. We account for the ARGO beamwidth and cali bration uncertainties, and we marginalize over the offset removed from the data. Our derived amplitudes of the CMB anisotropy detected by the ARGO exp eriment are smaller than those derived previously. We consider open and spa tially flat-Lambda cold dark matter cosmogonies, with the clustered-mass de nsity parameter Omega(o) in the range 0.1-1, the baryonic-mass density para meter Omega(B) in the range 0.005-0.029 h(-2), and the age of the universe t(o) in the range 10-20 Gyr. Marginalizing over all parameters but Omega(o) , the ARGO data favor an open (spatially flat-Lambda) model with Omega(o) = 0.23 (0.1). However, these numerical values are model dependent. At the 2 sigma confidence level, model normalizations deduced from the ARCO data are consistent with those drawn from the UCSB South Pole 1994, MAX 4 + 5, Whit e Dish, and SuZIE data sets. The ARGO open-model normalizations are also co nsistent with those deduced from the Differential Microwave Radiometer (DMR ) data. However, for most spatially hat-A models, the DMR normalizations ar e more than 2 sigma above the ARGO ones.
