Scaling transformations and the origins of light relics constraints from cosmic microwave background observations [PDF]

open access: yesPhysical Review D, 2022
We use here a family of scaling transformations, that scale key rates in the evolution equations, to analytically understand constraints on light relics from cosmic microwave background (CMB) maps, given cosmological models of varying degrees of ...

Dark Matter as dark dwarfs and other macroscopic objects: multiverse relics? [PDF]

open access: yesJournal of High Energy Physics, 2021
First order phase transitions can leave relic pockets of false vacua and their particles, that manifest as macroscopic Dark Matter. We compute one predictive model: a gauge theory with a dark quark relic heavier than the confinement scale.
