Discussion Overview
The discussion revolves around the search for published data sets that relate distance modulus to redshift, specifically over a range of redshift values from 0 to 5. Participants express challenges in combining data from various sources due to differing methodologies in estimating distance modulus.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant requests recommendations for papers or sources that provide distance modulus and redshift data over a large range.
- Another participant suggests a paper that describes different distance measures used in cosmology, providing a link to the Hogg paper.
- Some participants assert that discrepancies in publications may stem from incorrect analyses, emphasizing the importance of the Hogg paper for correct methodology.
- It is noted that reliable measurements of distance modulus at redshift z=5 are lacking, with current measurements primarily available for supernovae up to about z=2.
- A participant recommends the Union paper as a good compilation of current supernova data.
- Another participant points to Vizier as a potential resource for data.
- A specific data source for z versus bolometric magnitude for 1a supernovae is mentioned, although it only extends to z=1.4, and a question is raised about the need for understanding how to determine distance modulus from the provided data.
Areas of Agreement / Disagreement
Participants generally agree on the challenges of obtaining reliable distance modulus measurements at high redshifts, but there is no consensus on the best sources or methods for combining data from different publications.
Contextual Notes
Participants highlight limitations in the availability of accurate distance modulus measurements at high redshifts and the potential for errors in existing publications, but do not resolve these issues.
Who May Find This Useful
Researchers and students interested in cosmology, particularly those focusing on the relationship between distance modulus and redshift, may find this discussion relevant.
