Examination of frequency and scale dependence of CMB hemispherical power asymmetry
Sanjeev Sanyal, Pavan Kumar Aluri, Arman Shafieloo
In this study, we revisit the well-known cosmic microwave background (CMB) anomaly referred to as Hemispherical Power Asymmetry (HPA), using CMB temperature maps from the Planck mi…

A reassessment of LVE method and hemispherical power asymmetry in CMB temperature data from Planck PR4
Sanjeev Sanyal, Sanjeet K. Patel, Pavan K. Aluri +1
We undertake a reassessment of one of the large angular scale anomalies observed in cosmic microwave background (CMB) temperature signal referred to as Hemispherical Power Asymmetr…
