CMB isotropy anomalies and the local kinetic Sunyaev-Zel’dovich effect
CMB isotropy anomalies and the local kinetic Sunyaev-Zel’dovich effect
Several anomalies have been identified that may imply a breakdown of the statistical isotropy of the cosmic microwave background (CMB). In particular, an anomalous alignment of the quadrupole and octopole and a hemispherical power asymmetry have increased in significance as the data have improved. There have been several attempts to …
