Anomalies of low multipoles of WMAP and Planck missions: what are they ? Oleg Verkhodanov Special astrophysical observatory of Russian Academy of Sciences
Wilkinson Microwave Anisotropy Probe (WMAP, NASA) 2001 -2011 5 frequencies: 23, 33, 41, 61, 94 GHz Best determination of cosmological parameters in 2011 !
Planck mission, ESA 2010 -2013 Low Frequency Instrument: 30, 44, 70 HFI: 100, 143, 217, 353, 545, 857 GHz 1) 2) Zeldovich-Sunyaev effect 3) Gravitational waves in the B-mode of polarization ?
Observations
Data analysis of CMB Registration: time odered data: T(t)=T(l, b) Pixelization: map-making and restoration data in pixels Component separation Multipole analysis Pixel statistics of the CMB map Angular power spectrum analysis and determination of cosmological parameters
Component separation
WMAP observational bands
Component separation: Signal = (CMB + Synchrotron+dust+Free+radiosouces)*Beam + Noise
Two basic properties of CMB: 1) Black body emission — same temperature at all wavelengthes; 2) Correlation of CMB and foregrounds should be close to zero: because CMB is a random gaussian process

Let us go to data
Legacy Planck Archive (LPA) http: //www. sciops. esa. int/index. php? page=Planck_Legacy_Archive&project=planck 1) 4 CMB maps 2) maps at observational bands (30, 44, 70, 100, 143, 217, 353, 545, 857 GHz) 3) CO emission maps 4) Maps of dust 5) Maps of galactic low frequency emission (synchrotron + free-free) 6) Zodiac light maps 7) Maps of gravitational lensing 8) y-comptonization maps 9) Masks

«Bad» spots. . .
WMAP CMB anomalies 1) Cold Spot 2) Axis of Evil 3) Primirdial non-gaussinity (low limit by Planck data) 4) Violation of the power spectrum parity 5) Asymmetry 'North — South' in galactic coordinate system 6) New anomaly: too low amplitude of low harmonics
Let us look at some anomalies. . .
Cold Spot CMB NVSS Radio sources (Rudnick et al. , 2007) Cold Spot < -5 sigma Part of octupole 1) Huge Sachs-Wolfe effect (Rudnick et al, 2007) 2) Anistropic expansion (Jaffe et al. , 2005) 3) Topological defect [texture] (Cruz et al. , 2007, 2008, Planck 2013 ? ) 4) Artifact ? 5) Galactic phenomena (M. Hansen et al. , 2012)
Axis of Evil
Problems of WMAP quadrupole Amplitude Axis of Evil: planarity + alignment (Land & Magueijo, 2005)
What is the reason ? 1) Component separation (Doroshkevich, Verkhodanov, 2010) 2) Kouper Belt (Hansen et al. 2011) 3) Moving in Local Group of galaxies? (Tegmark et al. , 2004) 4) Something else. . . 5) It is absent. . .
Axis of Evil (Planck data) Copi et al. , ar. Xiv: 1311. 4562: direction of our motion exists
Primordial non-gaussianity ?
Primordial non-gaussianity ? 1) Obtained with bispectrum 2) Low multimoples anomalies exist

Observational channel of 217 GHz: what is unusual ?
Data of 217 GHz: what is unusual ? 1) Very close to CMB map outside the Galactic plane, but let us remember WMAP bands:
Data of 217 GHz: what is unusual ? 1) Close to the CMB map 2) Calibration problem ? (Spergel et al. , ar. Xiv: 1312. 3313) If remove the 217 GHz channel, then it can be obtained accurate restoration of the WMAP cosmology

Summary What have we wait for ? and what to do ? 1) WMAP and Planck data have practically the same low multipole anomalies 2) The difference of power spectra looks like one due to systematic effects of maps prepartion 3) We are waiting for a new release in June 2014: Maps of temperature anisotropy and polarization 4) Data are comparatively good (in resolution and sensetivity) when we take into account strangeness
