SUMMARY

This discussion focuses on deriving Hubble's constant using modern measurements of redshift and distance. The user successfully utilized data from the University of Washington's Hubble Law lab to calculate a Hubble constant value of 67.346 (km/s)/Mpc. The conversation highlights the importance of accurate data sources for astrophysical calculations, specifically mentioning the need for reliable measurements of redshift and distance to various galaxies.

PREREQUISITES
  • Understanding of Hubble's law
  • Familiarity with the Friedman equations
  • Knowledge of redshift measurements
  • Basic astrophysics concepts related to galaxy distances
NEXT STEPS
  • Research modern redshift measurement techniques
  • Explore the implications of Hubble's law in cosmology
  • Learn about the Friedman equations in detail
  • Investigate additional data sources for galaxy distance measurements
USEFUL FOR

Astronomers, astrophysicists, and students studying cosmology who are interested in calculating Hubble's constant and understanding the methodologies behind redshift and distance measurements in galaxies.

Hello.

I am in the middle of a paper on Hubble's law and the Friedman equations, I would like to show that with modern measurements of redshift (or λ') and distance, one can use these to find a modern value of Hubble's constant. I however need some data to do this, so does anybody know of a source where I can find usable measurements of redshift(or λ') and distance to different galaxies?

Thanks for your time.
