|Issue Date:||30-Jul-2009||Citation:||Anh, H.L.T.,Ng, S.C.C. (2009-07-30). Cosmological constraints on the local void with the union supernova compilation. International Journal of Modern Physics A 24 (18-19) : 3531-3537. ScholarBank@NUS Repository.||Abstract:||A simple inhomogeneous cosmological model with a local void is constrained with the latest Union supernova compilation. To fit the supernova data, a large local void on the scales of 1 Gpc is found, contrary to the small scales of 200 Mpc in the previous finding. A more realistic inhomogeneous cosmological model may be required to fit the supernova data. Alternatively, a clumpy universe with α < 1 can fit the supernova data with reduced local void scales. © 2009 World Scientific Publishing Company.||Source Title:||International Journal of Modern Physics A||URI:||http://scholarbank.nus.edu.sg/handle/10635/96118||ISSN:||0217751X|
