Bounds on Extended Gödel-Type Metrics from Type Ia Supernova Data

By Pankaj Jain A, Moninder S. Modgil A and John P. Ralston B


An extended Gödel universe which incorporates expansion along with rotation is compared to data from type 1a supernovas. The model does not conflict with any known cosmological observations. We obtain bounds on an anisotropic redshift versus magnitude relationship, and accompanying In this note we use large redshift type Ia Supernova data [1, 2, 3, 4, 5, 6, 7, 8] to place constraints upon parameters appearing in an anisotropic Gödel type line element. There is an interesting interplay between the redshift dependence and the anisotropy of the model which can be tested rathe
