Dark Energy or Apparent Acceleration Due to a Relativistic Cosmological Model More Complex than FLRW

摘要: We use the Szekeres inhomogeneous relativistic models in order to fit supernova combined data sets. show that with a choice of spatial curvature function is guided by current observations, almost as well LCDM model without requiring dark energy component. The were originally derived an exact solution Einstein's equations general metric has no symmetries and are regarded good candidates true lumpy universe we observe. null geodesics these not radial. best found also consistent requirement flatness at CMB scales. first results presented here seem encourage further investigations apparent acceleration using various other constraints from large structure need be explored next.
