A maximum-likelihood analysis of Pantheon+ supernovae finds a statistically significant dipole in the local Hubble expansion rate and in the deceleration parameter, which the authors interpret as evidence against a cosmological constant as the cause of cosmic acceleration.

abstract
We present a new version of a sample of galaxies from the Revised Flat Galaxy Catalogue (RFGC), which have redshift and HI line width data. We also give the parameters of the collective motion model determined upon this sample. The considered models of motion include the dipole (bulk flow), the quadrupole (cosmic shear) and the octupole components. We also considered higher-order multipoles. In all cases the obtained parameters matched the {\Lambda}CDM cosmology.

Anisotropy in Pantheon+ supernovae
A maximum-likelihood analysis of Pantheon+ supernovae finds a statistically significant dipole in the local Hubble expansion rate and in the deceleration parameter, which the authors interpret as evidence against a cosmological constant as the cause of cosmic acceleration.
