Omega_M and the CNOC Surveys
R. G. Carlberg, H. K. C. Yee, H. Lin +15
The CNOC1 cluster survey measures Omega_M via Oort's method, Omega_M= M/L x j/rho_c, where M/L is the field mass-to-light ratio, j is the field luminosity density and rho_c is the…

Omega baryon via Oort's Method
R. G. Carlberg, S. L. Morris, H. K. C. Yee +11
The baryon density of the universe is equal to the product of the baryon-to-light ratio, M_b/L, and the luminosity density, j. We estimate M_b/L as the sum of the masses of the X-r…
