Response to: "Isotropic deceleration and near-zero baseline acceleration in Pantheon+ supernovae: new arguments in the dark energy debate''
Animesh Sah, Mohamed Rameez, Subir Sarkar
Ray et al. [1] have claimed that the acceleration of the Hubble expansion rate inferred from Type Ia supernovae in the Pantheon+ catalogue "is equally strong in the CMB dipole ($q_…

Clustering properties of the CatWISE2020 quasar catalogue and their impact on the cosmic dipole anomaly
Sebastian von Hausegger, Nathan Secrest, Harry Desmond +3
The cosmic dipole anomaly -- the observation of a significant mismatch between the dipole observed in the matter distribution and that expected given the kinematic interpretation o…

Anisotropy in Pantheon+ supernovae
Animesh Sah, Mohamed Rameez, Subir Sarkar +1
We employ Maximum Likelihood Estimators to examine the Pantheon+ catalogue of Type Ia supernovae for large scale anisotropies in the expansion rate of the Universe. The analyses ar…
