Planck2018 results (2018, background): “A dipolar temperature power asymmetry has long been observed at the largest scales in the CMB (Eriksen et al. 2004), although its statistical significance is not high and is subject to a posteriori (look-elsewhere) corrections (Bennett et al.”
Local Voids as the Origin of Large-Angle Cosmic Microwave Background Anomalies. I. (2006, background): “…between the quadrupole and the octopole (Tegmark et al. 2003; de Oliveira-Costa et al. 2004); an anomalously cold spot on angular scales 10 (Vielva et al. 2004; Cruz et al. 2005, 2006); and an asymmetry in the largeangle power between opposite hemispheres (Eriksen et al. 2004; Hansen et al. 2004).”
SEVEN-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE (WMAP ) OBSERVATIONS: ARE THERE COSMIC MICROWAVE BACKGROUND ANOMALIES? (2010, methodology): “The first claimed hemispherical power asymmetry appeared in Eriksen et al. (2004), based on the first-year WMAP data, where a statistic for power asymmetry was constructed, and its value on high-resolution WMAP data was compared to an ensemble of Monte Carlo simulations in a direct frequentist…”

INCREASING EVIDENCE FOR HEMISPHERICAL POWER ASYMMETRY IN THE FIVE-YEAR WMAP DATA (2009, methodology): “Some early notable examples include unexpected low-ℓ correlations (de Oliveira-Costa et al. 2004), a peculiar large cold spot in the southern Galactic hemisphere (Vielva et al. 2004), and a dipolar distribution of large-scale power (Eriksen et al. 2004a).”
(An)isotropy of the Hubble diagram: comparing hemispheres (2007, methodology): “A similar study has been used by Eriksen et al. (2004) to analyse the cosmic microwave sky, which led to one of the several anomalies discovered in the WMAP data (see Copi et al. 2007 for a recent update and summary).”
SEVEN-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE (WMAP) OBSERVATIONS: COSMOLOGICAL INTERPRETATION (2010, methodology): “…et al. 2010) to measure the low-l TT power spectrum in l = 2 − 32, and calculate the likelihood using the Gibbs sampling and Blackwell-Rao (BR) estimator (Jewell et al. 2004; Wandelt 2003; Wandelt et al. 2004; O’Dwyer et al. 2004; Eriksen et al. 2004, 2007a,b; Chu et al. 2005; Larson et al. 2007).”
Testing the cosmological principle of isotropy: Local power spectrum estimates of the WMAP data (2004, background): “Moreover we investigate the recent claims of an asymmetry of the large scale structure between the northern and southern Galactic hemispheres (Park 2003; Eriksen et al. 2004a; Vielva et al. 2003; Eriksen et al. 2004b; Copi et al. 2003; Hansen et al. 2004).”
POWER ASYMMETRY IN WMAP AND PLANCK TEMPERATURE SKY MAPS AS MEASURED BY A LOCAL VARIANCE ESTIMATOR (2014, background): “Among these was one suggesting a directional dependency of the CMB angular power spectrum (Eriksen et al. 2004; Hansen et al. 2004), often referred to as a “hemispherical power asymmetry.””
