LiteBIRD Science Goals and Forecasts. -mode Anomalies
A. J. Banday, C. Gimeno-Amo, P. Diego-Palazuelos +101
Various so-called anomalies have been found in both the WMAP and Planck cosmic microwave background (CMB) temperature data that exert a mild tension against the highly successful b…
Planck PR4 (NPIPE) map-space cosmic birefringence
Raelyn Marguerite Sullivan, Arefe Abghari, Patricia Diego-Palazuelos +2
Cosmic birefringence is an effect where the plane of polarisation of the cosmic microwave background (CMB) is rotated by an angle through coupling to a hypothetical parity-vio…
Reassessment of the dipole in the distribution of quasars on the sky
Arefe Abghari, Emory F. Bunn, Lukas T. Hergt +4
We investigate recent claims by Secrest et al. of an anomalously large amplitude of the dipole in the distribution of CatWISE-selected quasars on the sky. Two main issues indicate…
Methods for CMB map analysis
Raelyn Marguerite Sullivan, Lukas Tobias Hergt, Douglas Scott
This introductory guide aims to provide insight to new researchers in the field of cosmic microwave background (CMB) map analysis on best practices for several common procedures. W…
