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…
Density reconstruction from biased tracers and its application to primordial non-Gaussianity
Omar Darwish, Simon Foreman, Muntazir M. Abidi +3
Large-scale Fourier modes of the cosmic density field are of great value for learning about cosmology because of their well-understood relationship to fluctuations in the early uni…
The Atacama Cosmology Telescope: Delensed Power Spectra and Parameters
Dongwon Han, Neelima Sehgal, Amanda MacInnis +39
We present LCDM cosmological parameter constraints obtained from delensed microwave background power spectra. Lensing maps from a subset of DR4 data from the Atacama Cosmology Tele…
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 Measurement of the Cosmic Microwave Background Power Spectra at 98 and 150 GHz
Steve K. Choi, Matthew Hasselfield, Shuay-Pwu Patty Ho +136
We present the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg of the 2013-2016 survey, which cove…
The Atacama Cosmology Telescope: DR4 Maps and Cosmological Parameters
Simone Aiola, Erminia Calabrese, Loïc Maurin +138
We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013…
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…
The Atacama Cosmology Telescope: Constraints on Cosmic Birefringence
Toshiya Namikawa, Yilun Guan, Omar Darwish +51
We present new constraints on anisotropic birefringence of the cosmic microwave background polarization using two seasons of data from the Atacama Cosmology Telescope covering $456…
