Gravitational lensing statistics with extragalactic surveys. IV. Joint constraints from gravitational lensing statistics and CMB anisotropies
J. F. Macias-Perez, P. Helbig, R. Quast +2
We present constraints on the cosmological constant lambda_0 and the density parameter Omega_0 from joint constraints from the analyses of gravitational lensing statistics of the J…

Gravitational lensing statistics with extragalactic surveys. III. Joint constraints on lambda_0 and Omega_0 from lensing statistics and the m-z relation for type Ia supernovae
Phillip Helbig
I present constraints on cosmological parameters in the lambda_0-Omega_0 plane from a joint analysis of gravitational lensing statistics (astro-ph/9904175) and the magnitude-redshi…
