Cluster profiles from beyond-the-QE CMB lensing mass maps
Sayan Saha, Louis Legrand, Julien Carron
Clusters of galaxies, being the largest collapsed structures in the universe, offer valuable insights into the nature of cosmic evolution. Precise calibration of the mass of cluste…
Improved cosmic microwave background (de-)lensing using general spherical harmonic transforms
Martin Reinecke, Sebastian Belkner, Julien Carron
Deep cosmic microwave background polarization experiments allow a very precise internal reconstruction of the gravitational lensing signal in pricinple. For this aim, likelihood-ba…
The Atacama Cosmology Telescope: A Measurement of the DR6 CMB Lensing Power Spectrum and its Implications for Structure Growth
Frank J. Qu, Blake D. Sherwin, Mathew S. Madhavacheril +155
We present new measurements of cosmic microwave background (CMB) lensing over sq. deg. of the sky. These lensing measurements are derived from the Atacama Cosmology Telescop…
Robust and efficient CMB lensing power spectrum from polarization surveys
Louis Legrand, Julien Carron
Deep surveys of the CMB polarization have more information on the lensing signal than the quadratic estimators (QE) can capture. We showed in a recent work that a CMB lensing power…
