| 英文摘要 | The information of Omega(Lambda) of a hat universe is extracted from K band galaxy number counts, without using evolution (NE) models. Cowie ct al.'s observations, with model input luminosity functions taken from Efstathiou et al. (1988), Loveday et al. (1992) and Mobasher et al. (1993), give (nh) in the range: 0.59 similar to 0.81 plus a typical random error of sigma(Omega Lambda) = 0.2-0.1, respectively. Keek's observations give Omega(Lambda) = 0.9. We conclude that either the normalization of nearby luminosity function is too high or the cosmological constant cannot be too large. |
