Closing in on the large-scale CMB power asymmetry
D. Contreras, J. Hutchinson, A. Moss +2
Measurements of the cosmic microwave background (CMB) temperature anisotropies have revealed a dipolar asymmetry in power at the largest scales, in apparent contradiction with the…
Planck intermediate results. LIII. Detection of velocity dispersion from the kinetic Sunyaev-Zeldovich effect
Planck Collaboration, N. Aghanim, Y. Akrami +141
Using the full-mission data, we present a detection of the temperature (and therefore velocity) dispersion due to the kinetic Sunyaev-Zeldovich (kSZ) effect from clu…
Exploring Cosmic Origins with CORE: Survey requirements and mission design
J. Delabrouille, P. de Bernardis, F. R. Bouchet +200
Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this p…
Constraints on direction-dependent cosmic birefringence from Planck polarization data
Dagoberto Contreras, Paula Boubel, Douglas Scott
Cosmic birefringence is the process that rotates the plane of polarization by an amount, , as photons propagate through free space. Such an effect arises in parity-violating ext…
Exploring cosmic origins with CORE: effects of observer peculiar motion
C. Burigana, C. S. Carvalho, T. Trombetti +116
We discuss the effects on the CMB, CIB, and thermal SZ effect due to the peculiar motion of an observer with respect to the CMB rest frame, which induces boosting effects. We inves…
Testing physical models for dipolar asymmetry with CMB polarization
D. Contreras, J. P. Zibin, D. Scott +2
The cosmic microwave background (CMB) temperature anisotropies exhibit a large-scale dipolar power asymmetry. To determine whether this is due to a real, physical modulation or is…
