SUMMARY

The discussion focuses on the redshifts associated with significant early events in the universe. The recombination era occurs at a redshift of z = 1100, while the reionization era is identified within the range of z = 15-20. The user seeks additional information regarding the "Dark Ages" redshift and requests resources for understanding the calculation of these redshift values. The conversation highlights the importance of accurate redshift data in cosmological research.

PREREQUISITES
  • Understanding of cosmological redshift concepts
  • Familiarity with the timeline of the early universe
  • Basic knowledge of astrophysics
  • Experience with astronomical data interpretation
NEXT STEPS
  • Research the redshift values associated with the "Dark Ages" period
  • Study the methods for calculating redshift in cosmology
  • Explore resources on the cosmic microwave background radiation
  • Learn about the implications of redshift in understanding the universe's expansion
USEFUL FOR

Astronomers, astrophysics students, and researchers interested in the early universe and cosmological events.

Hi,

I am researching several historic eras of the early universe and part of what I need to find is at what redshifts these events occurred. I have z = 1100 for the recombination era and z = 15-20 for the reinonization era. I haven't been able to turn up this info the "Dark Ages" yet. Any help is appreciated. And I'd be grateful if someone could point me to a good site (beginner level) on how these redshift numbers are calculated. Thank you.

Thanks, Ambitwistor. I don't know what I'd do without you! I appreciate your help now as well as in previous posts.
