Scrutinizing Exotic Cosmological Models Using ESSENCE Supernova Data Combined with Other Cosmological Probes

摘要: The first cosmological results from the ESSENCE supernova survey (Wood-Vasey et al. 2007) are extended to a wider range of models including dynamical dark energy and non-standard models. We fold in greater number external data sets such as recent Higher-z release high-redshift supernovae (Riess well several complementary probes.
