Is There Evidence for a Hubble Bubble? The Nature of SN Ia Colors And Dust in External Galaxies

We examine recent evidence from the luminosity-redshift relation of Type Ia Supernovae for the {approx} 3 {sigma} detection of a ''Hubble bubble'' -- a departure of the local value of the Hubble constant from its globally averaged value. By comparing the MLCS2k2 fits used in that...
