TL;DR
This paper presents evidence suggesting late-time dark matter creation in the universe, based on combined analysis of matter power spectrum, supernovae distances, and CMB anisotropy data.
Contribution
It provides the first joint analysis indicating cosmological dark matter creation at 95% confidence level, integrating multiple observational data sets.
Findings
Evidence for late-time dark matter creation at 95% confidence
Consistent results across matter power spectrum, supernovae, and CMB data
Supports alternative cosmological models with particle creation
Abstract
A joint analysis of the linear matter power spectrum, distance measurements from type Ia supernovae and the position of the first peak in the anisotropy spectrum of the cosmic microwave background indicates a cosmological, late-time dark matter creation at 95% confidence level.
