Discover the Latest Cosmological Parameters for the CDM Lambda Concordance Model

Click For Summary

Discussion Overview

The discussion centers on the most up-to-date cosmological parameters within the cold dark matter Lambda concordance model, specifically focusing on values for Hubble's constant (Ho), matter density parameter (Omega m), and dark energy density parameter (Omega Lambda). Participants are seeking reliable sources for the latest accepted values and discussing the accuracy of various data releases.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant is looking for the most current and widely accepted values for Ho, Omega m, and Omega Lambda, noting discrepancies between their textbook and more recent papers.
  • Another participant suggests using Google to search for the parameters directly.
  • A third participant references the 2015 PLANCK data release as the most recent source of cosmological parameters, emphasizing that the focus should be on increasing accuracy rather than acceptance.
  • The original poster questions whether the PLANCK data is indeed accepted as the most accurate, indicating a concern about the contested nature of such data.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the acceptance of the PLANCK data as the most accurate source, with some expressing uncertainty about its contested status.

Contextual Notes

The discussion reflects varying levels of familiarity with the latest research and the potential for differing interpretations of data accuracy and acceptance within the cosmological community.

Cosmological paramaters in the cold dark matter Lamda concordance model.

I have been trying to find the most
uptodate values for Ho , Ohmega m and Ohmega Lamgad

I was wondering if anyone knows where I might find the most reliably, widely accepted values for these values that are currently known?

The textbook I am using was published in 2010 gives: Ho 72 kms^-1Mpc^-1 Ohmega Lamda 0.742. Ohmega m 0.358 (this includes all contributions from baryonic matter and dark matter etc.). I found though a more recent paper which seemed to be giving a lower value of about 69 for Ho and slightly different values for the other paramaters. So like I say, is there somewhere where I can find the most accepted values known today?
 
Space news on Phys.org
Try google with the name of the parameters
 
2015 PLANCK data release is the most recent, I believe:
https://arxiv.org/abs/1502.01589

It's not the matter of what's accepted, but of increasing accuracy.
 
Thanks. So it is accepted then the Planck data is the most accurate to date? The reason I ask this is because I had been wading through so much, which is why I was using the word accepted, meaning the it is not contested that the Planck data is the most accurate. Any way I will use this data - thanks
