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…
Eternal inflation bubble collision signature on CMB remote dipole and quadrupole fields
Hongbo Cai, Pengjie Zhang, Yilun Guan
The remote dipole and quadrupole fields (RDF/RQF) encode information about the observable universe as seen from remote places within our past light cone. Sensitive to the superhori…
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: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
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…
Probing Time-Dependent Physics with Phase-Folding CMB Maps
Yilun Guan
Time-resolved observations of the Cosmic Microwave Background (CMB) offer a powerful probe of time-dependent cosmological signals, such as a stochastic gravitational wave backgroun…
