The low multipoles in the Pantheon+SH0ES data

Understand

In previous work we have shown that the dipole in the low redshift supernovae of the Pantheon+SH0ES data does not agree with the one inferred from the velocity of the solar system as obtained from CMB data.

• We interpreted this as the presence of significant bulk velocities.
• In this paper we study the monopole, dipole and quadrupole in the Pantheon+SH0ES data.
• We find that in addition to the dipole also both, the monopole and the quadrupole are detected with high significance.
