Acesso restrito. p. 1-13In this paper we study an anisotropic model generated from a particular Bianchi type-III metric, which is a generalization of G¨odel’s metric and an exact solution of Einstein’s field equations. We analyse type Ia supernova data, namely the SDSS sample calibrated with the MLCS2k2 fitter, and we verify in which ranges of distances and redshifts the anisotropy could be observed. We also consider, in a joint analysis, the position of the first peak in the CMB anisotropy spectrum, as well as current observational constraints on the Hubble constant. We conclude that a small anisotropy is permitted by the data, and that more accurate measurements of supernova distances above z = 2 might indicate the existence of such anisotropy in the universe.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-06-25T19:51:57Z No. of bitstreams: 1 4444444444aaaa.pdf: 1304691 bytes, checksum: eec6ca4e0e6fd3a248352ae028e914a7 (MD5)Approved for entry into archive by Rodrigo Meirelles(rodrigomei@ufba.br) on 2013-08-16T13:00:19Z (GMT) No. of bitstreams: 1 4444444444aaaa.pdf: 1304691 bytes, checksum: eec6ca4e0e6fd3a248352ae028e914a7 (MD5)Made available in DSpace on 2013-08-16T13:00:19Z (GMT).
