What is the reason for density perturbations in the CMB?

Click For Summary
SUMMARY

The discussion centers on the origins of density perturbations in the Cosmic Microwave Background (CMB). Participants explore the possibility that these perturbations may originate from primordial black holes. Additionally, references to a series of Insights articles on Physics Forums, specifically articles 3, 4, and 5, provide further insights into the topic of CMB perturbations.

PREREQUISITES
  • Understanding of Cosmic Microwave Background (CMB) theory
  • Familiarity with primordial black holes
  • Basic knowledge of cosmological perturbation theory
  • Experience with astrophysical research methodologies
NEXT STEPS
  • Read the Insights articles on CMB perturbations, specifically articles 3, 4, and 5
  • Research the role of primordial black holes in cosmology
  • Study the mathematical framework of cosmological perturbation theory
  • Explore observational techniques for measuring CMB fluctuations
USEFUL FOR

Astronomers, cosmologists, and physics students interested in the origins of cosmic structures and the implications of primordial black holes on the CMB.

I could not find an answer by checking the web. Could these perturbations originate from primordial black holes? What else?
