The Atacama Cosmology Telescope is a 6-meter telescope designed to map the Cosmic Microwave Background simultaneously at 145 GHz, 215 GHz, and 280 GHz with arcminute resolution. Each frequency will have a 32 by 32 element focal plane array of TES bolometers. This paper describes the design of the telescope and the cold reimaging optics, which is optimized for millimeter-wave observations with these sensitive detectors.

  1. Primordial Physics in the Nonlinear Universe: Revealing the oscillating halo bias from cosmological collider models

    astro-ph.CO 2026-07 accept novelty 7.0 of 10

    A binning-based IC method yields the first N-body measurements of oscillating halo bias from cosmological collider bispectra, with mass- and assembly-dependent phases fit by peak-background-split theory.

  2. Impact of Galactic non-Gaussian foregrounds on CMB lensing measurements

    astro-ph.CO 2025-05 conditional novelty 6.0 of 10

    Galactic dust bias on CMB lensing amplitude is below 0.3σ for ACT but can exceed 0.3σ for Simons Observatory with wide masks, depending on the dust model.
