Primordial Black Hole Formation in Modified Gravity
Analysis
This paper explores the formation of primordial black holes (PBHs) within a specific theoretical framework (Higgs hybrid metric-Palatini model). It investigates how large density perturbations, originating from inflation, could have led to PBH formation. The study focuses on the curvature power spectrum, mass variance, and mass fraction of PBHs, comparing the results with observational constraints and assessing the potential of PBHs as dark matter candidates. The significance lies in exploring a specific model's predictions for PBH formation and its implications for dark matter.
Key Takeaways
