The Atacama Cosmology Telescope: Passband Measurements with an Analysis of Systematic Errors

Thomas Alford, Rahul Datta, Erminia Calabrese +14

We present measurements of the spectral response of the four Advanced ACTPol (AdvACT) multichroic detector arrays, which observed in frequency bands centered near 30, 40, 90, 150,…

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 Simons Observatory: Development of a Pipeline to Detect Rapid Transients in Time-Ordered Data

Justin Clancy, Carlo Bacciagalupi, Josh Borrow +13

We introduce a method for detecting astrophysical transients evolving on timescales of milliseconds to minutes using cosmic microwave background (CMB) survey telescopes. While prev…

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…

A Search for Millimeter-Bright Blazars as Astrophysical Neutrino Sources

R. Abbasi, M. Ackermann, J. Adams +424

The powerful jets of blazars have been historically considered as likely sites of high-energy cosmic-ray acceleration. However, particulars of the launched jet and the locations of…
