The Atacama Cosmology Telescope: Constraints on the anisotropic screening and birefringence effects with DR6
Darby M. Kramer, Alexander van Engelen, Frank J. Qu +14
While we have learned much from recent surveys of the mm-wave sky, many secondary anisotropies of the CMB remain under-explored. We consider two of these here: the anisotropic scre…
Characterising the epoch of reionisation using the cross-correlation of the kSZ effect and CMB lensing
Niall MacCrann, Christopher Cain, Aleksandra Kusiak +5
We investigate the cross-correlation of the kinematic Sunyaev-Zeldovich (kSZ) effect with lensing of the cosmic microwave background (CMB) as a probe of the epoch of reionisation.…
The Atacama Cosmology Telescope: A demonstration of CMB lensing measurement from daytime data
Irene Abril-Cabezas, Frank J. Qu, Joshua Kim +30
We present a cosmic microwave background (CMB) lensing power spectrum analysis using daytime data (11am-11pm UTC) gathered by the Atacama Cosmology Telescope (ACT) over the period…
CMB component-separated power spectrum estimation by Spectral Internal Linear Combination (SpILC)
Jack Y. L. Kwok, William R. Coulton, Niall MacCrann +3
Component separation methods mitigate the cross-contamination between different extragalactic and galactic contributions to cosmic microwave background (CMB) data. This is often do…
