Optimizing foreground mitigation for CMB lensing with combined multifrequency and geometric methods
Omar Darwish, Blake D. Sherwin, Noah Sailer +2
A key challenge for current and upcoming CMB lensing measurements is their sensitivity to biases from extragalactic foregrounds, such as Sunyaev-Zeldovich (SZ) signals or cosmic in…
The Atacama Cosmology Telescope: Summary of DR4 and DR5 Data Products and Data Access
Maya Mallaby-Kay, Zachary Atkins, Simone Aiola +57
Two recent large data releases for the Atacama Cosmology Telescope (ACT), called DR4 and DR5, are available for public access. These data include temperature and polarization maps…
Partially Constrained Internal Linear Combination: a method for low-noise CMB foreground mitigation
Y. Sultan Abylkairov, Omar Darwish, J. Colin Hill +1
Internal Linear Combination (ILC) methods are some of the most widely used multi-frequency cleaning techniques employed in CMB data analysis. These methods reduce foregrounds by mi…
Strong detection of the CMB lensingxgalaxy weak lensingcross-correlation from ACT-DR4,PlanckLegacy and KiDS-1000
Naomi Clare Robertson, David Alonso, Joachim Harnois-Déraps +48
We measure the cross-correlation between galaxy weak lensing data from the Kilo Degree Survey (KiDS-1000, DR4) and cosmic microwave background (CMB) lensing data from the Atacama C…
The Atacama Cosmology Telescope: DR5 maps of 18,000 square degrees of the microwave sky from ACT 2008-2018 data
Sigurd Naess, Simone Aiola, Jason E. Austermann +59
This paper presents a maximum-likelihood algorithm for combining sky maps with disparate sky coverage, angular resolution and spatially varying anisotropic noise into a single map…
The Atacama Cosmology Telescope: A CMB lensing mass map over 2100 square degrees of sky and its cross-correlation with BOSS-CMASS galaxies
Omar Darwish, Mathew S. Madhavacheril, Blake Sherwin +50
We construct cosmic microwave background lensing mass maps using data from the 2014 and 2015 seasons of observations with the Atacama Cosmology Telescope (ACT). These maps cover 21…
