The Simons Observatory: Design and Initial Performance of the Detector Readout System for the Large-Aperture Telescope

Thomas P. Satterthwaite, Tristan Pinsonneault-Marotte, Shawn W. Henderson +34

We present the design, implementation, and initial performance of a highly multiplexed cryogenic superconducting detector readout system in the context of its deployment to the Sim…

The Atacama Cosmology Telescope: Probing new signatures of ultralight axions with gravitational lensing

Alex Laguë, Keir K. Rogers, Mathew S. Madhavacheril +14

Ultralight axions (ULAs) are well-motivated dark matter particle candidates that arise in many extensions of the Standard Model of particle physics. ULAs with mass $m_\mathrm{a} \l…

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 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…
