The Cosmic Microwave Background (CMB) anisotropy power on the largest angular scales observed both by WMAP and COBE DMR appears to be lower than the one predicted by the standard model of cosmology with almost scale free primordial perturbations arising from a period of inflation. One can either interpret this as a manifestation of cosmic variance or as a physical effect that requires an explanation. We discuss various mechanisms that could be responsible for the suppression of such low l… 
Suppression of the Low-ℓ Multipoles of the CMB Anisotropy Spectrum as the Dark Energy Effect on Inflation
Confirmed by the WMAP 7-year results, the quadrupole Cl(l = 2) moment of the angular power spectrum of the Cosmic Microwave Background(CMB) temperature fluctuations has an anomalously low amplitude
Punctuated inflation and the low CMB multipoles
We investigate inflationary scenarios driven by a class of potentials which are similar in form to those that arise in certain minimal supersymmetric extensions of the standard model. We find that
Suppressing CMB low multipoles with ISW effect
Recent results of Planck data reveal that the power [1,2] in the low multipoles of the CMB angular power spectrum, approximately up to l = 30, is significantly lower than the theoretically predicted
Stochastic inflation and the lower multipoles in the cosmic microwave background anisotropies
We generalize the treatment of inflationary perturbations to deal with the non-Markovian coloured noise emerging from any realistic approach to stochastic inflation. We provide a calculation of the
Joint Planck and WMAP Assessment of Low CMB Multipoles
The remarkable progress in cosmic microwave background (CMB) studies over past decade has led to the era of precision cosmology in striking agreement with the $\Lambda$CDM model. However, the lack of
Inflation in the closed FLRW model and the CMB
Recent cosmic microwave background (CMB) observations put strong constraints on the spatial curvature via estimation of the parameter Ωk assuming an almost scale invariant primordial power spectrum.
Significance of the largest scale CMB fluctuations in WMAP
We investigate anomalies reported in the Cosmic Microwave Background maps from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite on very large angular scales and discuss possible
A Bayesian analysis of inflationary primordial spectrum models using Planck data
The current available CMB data show an anomalously low value of the CMB temperature fluctuations at large angular scales (l < 40). This lack of power is not explained by the minimal LCDM model, and
Primordial power spectrum from WMAP
Increasingly accurate measurements of the anisotropy in the temperature of the cosmic microwave background ~CMB! has ushered in an era of precision cosmology. A golden decade of CMB anisotropy
Does the small CMB quadrupole moment suggest new physics
Motivated by WMAP's confirmation of an anomalously low value of the quadrupole moment of the CMB temperature fluctuations, we investigate the effects on the CMB of cutting off the primordial power

Two‐point anisotropies in WMAP and the cosmic quadrupole
Large-scale modes in the temperature anisotropy power spectrum C l measured by the Wilkinson Microwave Anisotropy Probe (WMAP) seem to have lower amplitudes (C 2 , C 3 and C 4 ) than that expected in

We report the most complete analysis to date of observations of the cosmic microwave background (CMB) obtained during the 1998 flight of BOOMERANG. We use two quite different methods to determine the
