Maximum likelihood kinetic Sunyaev Zel'dovich velocity reconstruction
Dagoberto Contreras, Fiona McCarthy, Matthew C. Johnson
The kinetic Sunyaev Zel'dovich (kSZ) effect, cosmic microwave background (CMB) temperature anisotropies induced by the scattering of CMB photons from free electrons, will be measur…
Planck intermediate results. LVI. Detection of the CMB dipole through modulation of the thermal Sunyaev-Zeldovich effect: Eppur si muove II
Planck Collaboration, Y. Akrami, M. Ashdown +126
The largest temperature anisotropy in the cosmic microwave background (CMB) is the dipole, which has been measured with increasing accuracy for more than three decades, particularl…
Cosmology in front of the background: studying the growth of structure at CMB wavelengths
Douglas Scott, J. Richard Bond, Scott Chapman +6
Canada has thriving communities in CMB (cosmic microwave background) studies, cosmology and submillimetre (submm) astronomy, with involvement in many facilities that featured promi…
Planck 2018 results. VII. Isotropy and Statistics of the CMB
Planck Collaboration, Y. Akrami, M. Ashdown +147
Analysis of the Planck 2018 data set indicates that the statistical properties of the cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with pre…
Towards detection of relativistic effects in galaxy number counts using kSZ Tomography
Dagoberto Contreras, Matthew C. Johnson, James B. Mertens
High-resolution, low-noise observations of the cosmic microwave background (CMB) planned for the near-future will enable new cosmological probes based on re-scattered CMB photons -…
Cosmological constraints on sterile neutrino oscillations from Planck
Alan M. Knee, Dagoberto Contreras, Douglas Scott
Both particle physics experiments and cosmological surveys can constrain the properties of sterile neutrinos, but do so with different parameterizations that naturally use differen…
Planck 2018 results. X. Constraints on inflation
Planck Collaboration, Y. Akrami, F. Arroja +173
We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. The results are fully consistent with the two previous Planck cosm…
Planck 2018 results. VI. Cosmological parameters
Planck Collaboration, N. Aghanim, Y. Akrami +179
We present cosmological parameter results from the final full-mission Planck measurements of the CMB anisotropies. We find good consistency with the standard spatially-flat 6-param…
Planck 2018 results. I. Overview and the cosmological legacy of Planck
Planck Collaboration, Y. Akrami, F. Arroja +188
The European Space Agency's Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave…
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…
Planck intermediate results. XLIX. Parity-violation constraints from polarization data
Planck Collaboration, N. Aghanim, M. Ashdown +148
Parity violating extensions of the standard electromagnetic theory cause in vacuo rotation of the plane of polarization of propagating photons. This effect, also known as cosmic bi…
The information content of cosmic microwave background anisotropies
Douglas Scott, Dagoberto Contreras, Ali Narimani +1
The cosmic microwave background (CMB) contains perturbations that are close to Gaussian and isotropic. This means that its information content, in the sense of the ability to const…
Testing physical models for dipolar asymmetry: from temperature to k space to lensing
J. P. Zibin, D. Contreras
One of the most intriguing hints of a departure from the standard cosmological model is a large-scale dipolar power asymmetry in the cosmic microwave background (CMB). If not a sta…

We present the 8th Full Focal Plane simulation set (FFP8), deployed in support of the Planck 2015 results. FFP8 consists of 10 fiducial mission realizations reduced to 18144 maps,…
Searching for concentric low variance circles in the cosmic microwave background
