Exploring cosmic origins with CORE: gravitational lensing of the CMB
Anthony Challinor, Rupert Allison, Julien Carron +110
Lensing of the CMB is now a well-developed probe of large-scale clustering over a broad range of redshifts. By exploiting the non-Gaussian imprints of lensing in the polarization o…
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…
Maximum a posteriori CMB lensing reconstruction
Julien Carron, Antony Lewis
Gravitational lensing of the CMB is a valuable cosmological signal that correlates to tracers of large-scale structure and acts as a important source of confusion for primordial $B…
Internal delensing of Planck CMB temperature and polarization
Julien Carron, Antony Lewis, Anthony Challinor
We present a first internal delensing of CMB maps, both in temperature and polarization, using the public foreground-cleaned (SMICA) Planck 2015 maps. After forming quadratic estim…
