Low-multipole E-B chirality bounds in Planck PR4 with an exact-arithmetic pipeline

Methods-and-bounds paper. No detection is claimed. The low-multipole (ℓ=2..8) polarization of the Planck PR4 (NPIPE) 100 and 143 GHz maps is analysed with an end-to-end exact-arithmetic pipeline (dyadic–triadic rationals, integer mantissa; ingestion of all 604,127,232 map values...

A logarithmic descent relation for the aligned CMB quadrupole-octopole system

Methods-and-measurement paper. A new observable for the CMB quadrupole–octopole alignment: in the axial frame of the aligned 2⊕3 system, the ring-averaged profile near a node of the odd multipole obeys D(z) = n·log2(1/|z|) + C — integer slope fixed by topology (the node order), i...
