The Topology of the Universe
Craig J. Copi, Deyan P. Mihaylov, Anna Negro +14
Is the Universe infinite in all directions? The only way to know is to look. A non-trivial cosmic topology would imprint subtle signatures on the cosmic microwave background (CMB)…
CMB Constraints on Pre-Inflationary Axion Dark Matter Isocurvature
Catherine Petretti, Praniti Singh, Matteo Braglia +3
Although measurements of the Cosmic Microwave Background (CMB) are consistent with a nearly scale-invariant primordial spectrum of adiabatic perturbations, in which the energy dens…
Quantum Signatures of Cosmic Topology: How Casimir Backreaction Transmits Isotropy Violation
Anna Negro, Kurt Hinterbichler, Glenn D. Starkman +17
A finite, scheme-independent Casimir contribution to the stress-energy tensor arises naturally for quantum fields in universes with non-trivial spatial topology. We compute this Ca…
Investigating the Origin of CMB Large-Scale Features Using LiteBIRD and CMB-S4
Catherine Petretti, Matteo Braglia, Xingang Chen +2
Several missions following Planck are currently under development, which will provide high-precision measurements of the Cosmic Microwave Background (CMB) anisotropies. Specificall…
Evaluation of the ngVLA Revision D array configuration for stellar imaging
Catherine G. Petretti, Kazunori Akiyama, Lynn D. Matthews
A transformative science case for the proposed next-generation Very Large Array (ngVLA) is resolving the surfaces of nearby stars, both spatially and temporally, enabled by the com…
