Testing the anisotropy of cosmic acceleration from Pantheon supernovae sample
Z. Q. Sun, F. Y. Wang
In this paper, we study the anisotropy of cosmic acceleration the using Pantheon sample, which includes 1048 spectroscopically confirmed Type Ia supernovae (SNe Ia) covering the re…

Probing the isotropy of cosmic acceleration using different supernova samples
Z. Q. Sun, F. Y. Wang
Recent studies have indicated that an anisotropic cosmic expansion may exist. In this paper, we use three datasets of type Ia supernovae (SNe Ia) to probe the isotropy of cosmic ac…
