The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect
Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38
The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…
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…
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…
The Atacama Cosmology Telescope: DR6 Power Spectrum Foreground Model and Validation
Benjamin Beringue, Kristen M. Surrao, J. Colin Hill +28
We discuss the model of astrophysical emission at millimeter wavelengths used to characterize foregrounds in the multi-frequency power spectra of the Atacama Cosmology Telescope (A…
Atacama Cosmology Telescope: Observations of supermassive black hole binary candidates. Strong sinusoidal variations at 95, 147 and 225 GHz in PKS 2131021 and PKS J08050111
Adam D. Hincks, Xiaoyi Ma, Przemek Mróz +23
Large sinusoidal variations in the radio light curves of the blazars PKS J08050111 and PKS 2131021 have recently been discovered with an 18-year monitoring programme at the O…
The Simons Observatory: Assessing the Impact of Dust Complexity on the Recovery of Primordial -modes
Yiqi Liu, Susanna Azzoni, Susan E. Clark +14
We investigate how dust foreground complexity can affect measurements of the tensor-to-scalar ratio, , in the context of the Simons Observatory, using a cross-spectrum component…
