Inflation at the End of 2025: Constraints on and Using the Latest CMB and BAO Data
L. Balkenhol, E. Camphuis, F. Finelli +10
Inflation elegantly provides initial conditions for the standard model of cosmology, while solving the horizon, flatness, and magnetic monopole problems. Inflationary models make p…
Towards constraining cosmological parameters with SPT-3G observations of 25% of the sky
A. Vitrier, K. Fichman, L. Balkenhol +103
The South Pole Telescope (SPT), using its third-generation camera, SPT-3G, is conducting observations of the cosmic microwave background (CMB) in temperature and polarization acros…
SPT-3G D1: Axion Early Dark Energy with CMB experiments and DESI
A. R. Khalife, L. Balkenhol, E. Camphuis +92
We present the most up-to-date constraints on axion early dark energy (AEDE) from cosmic microwave background (CMB) and baryon acoustic oscillation (BAO) measurements. In particula…
Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing
Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143
We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…
The End of Easy Phenomenology for CMB Experiments: A Case Study in the Dark Sector
Cynthia Trendafilova, Ali Rida Khalife, Silvia Galli
The precision of Cosmic Microwave Background (CMB) experiments, specifically its lensing reconstruction, has reached the limit where non-linear corrections cannot be ignored. Negle…
