Avoiding bias in measurements of fundamental constants from high resolution quasar spectra
John K. Webb, Chung-Chi Lee, Dinko Milaković
Recent advances in spectroscopic instrumentation and calibration methods dramatically improve the quality of quasar spectra. Supercomputer calculations show that, at high spectral…
