Tests with public data
In the expansion tests, we compare dark energy models using supernova data and other cosmological probes. For example, we repeat a fit after removing one redshift range from the sample to measure how that choice affects the result. Other research areas cover structure growth and the selection of distant sources in catalogues.
How the tests are run
The test criterion is set before calculation. The Tower holds the internal records. The catalogue shows the summaries cleared for release, with their test conditions and available sources.
Automation runs and checks calculations. Dener Pereira decides how to interpret the results and what can be made public.
Scientific responsibility
Dener Pereira conducts the research and declares his academic affiliation with the Federal University of Rio de Janeiro (UFRJ). NEXO is an independent project.
How to propose a check
Use the record identifier to say which fit, sample cut or hypothesis you want to check. Each result has a status in the catalogue. Status changes are recorded editorial decisions.
