The UVES Large Program for testing fundamental physics I. Bounds on a change in α towards quasar HE 2217−2818
Open accessAbstract
Context. Absorption-line systems detected in quasar spectra can be used to compare the value of the fine-structure constant, α, measured today on Earth with its value in distant galaxies. In recent years, some evidence has emerged of small temporal and also spatial variations in α on cosmological scales. These variations may reach a fractional level of ≈ 10 ppm (parts per million).

In the citing paper
“Trying to confirm these results was the main motivation for an ESO/UVES Large Program (Molaro et al. 2013;Rahmani et al. 2013;Evans et al. 2014), a dedicated program to test for the variation of fundamental constants with an optimized sample and methodology with about 40 VLT nights of observations over 2010-2013 with a typical resolution of R $ 60 000 and a signal-to-noise per pixel of order 100,”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
