Ultra-light axion constraints from Planck and ACT: the role of nonlinear modelling
Lauren Gaughan, Anne M. Green, Adam Moss
We study how constraints on the abundance of ultralight axions (ULAs) from cosmic microwave background (CMB) data depend on their nonlinear modelling. We focus on the axion mass ra…
CMB anisotropies from cosmic (super)strings in light of ACT DR6
Juhan Raidal, Anastasios Avgoustidis, Edmund Copeland +1
We present updated constraints on cosmic string and superstring parameters derived from Cosmic Microwave Background (CMB) anisotropies. The constraints are obtained via Markov Chai…
The stochastic gravitational wave background from cosmic superstrings
Anastasios Avgoustidis, Edmund J. Copeland, Adam Moss +1
We study the stochastic gravitational wave background sourced by a network of cosmic superstrings and demonstrate that incorporating higher-mass string species, beyond the fundamen…
Scaling solutions as Early Dark Energy resolutions to the Hubble tension
Edmund J. Copeland, Adam Moss, Sergio Sevillano Muñoz +1
A wide class of scalar field models including Quintessence and K-essence have the attractive property of tracker regimes, where the energy density stored in the field evolves so as…
Closing in on the large-scale CMB power asymmetry
D. Contreras, J. Hutchinson, A. Moss +2
Measurements of the cosmic microwave background (CMB) temperature anisotropies have revealed a dipolar asymmetry in power at the largest scales, in apparent contradiction with the…
Constraints on the fundamental string coupling from B-mode experiments
Anastasios Avgoustidis, Edmund J. Copeland, Adam Moss +3
We study signatures of cosmic superstring networks containing strings of multiple tensions and Y-junctions, on the cosmic microwave background (CMB) temperature and polarisation sp…
