Absolute Magnitude Test: Testing Cosmological Models Based on Compilations of Supernovae SNe Ia "Union" and "Union2"
Advances in Astrophysics
In the present work, on the basis of compilations of supernovae Sne Ia Union and Union2, two cosmological models describing the Universe are considered. One of them (a model with a cosmological constant of zero) was widespread until 1998 when a study of type Ia supernovae showed that the Universe is expanding at an accelerating rate. After that, a model for the case of a flat universe, which is also discussed in this paper, received great recognition. To accept or reject any cosmological model,doi:10.22606/adap.2020.51003 fatcat:6d3smz6tt5ajbh4hdpitpktncu
