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…
