Getting the model right; an information criterion for spectroscopy
John K. Webb, Chung-Chi Lee, Robert F. Carswell +1
Robust model-fitting to spectroscopic transitions is a requirement across many fields of science. The corrected Akaike and Bayesian information criteria (AICc and BIC) are most fre…
A new era of fine structure constant measurements at high redshift
Dinko Milaković, Chung-Chi Lee, Robert F. Carswell +3
New observations of the quasar HE05154414 have been made using the HARPS spectrograph on the ESO 3.6m telescope, aided by the Laser Frequency Comb (LFC). We present three import…
Artificial intelligence and quasar absorption system modelling; application to fundamental constants at high redshift
Chung-Chi Lee, John K. Webb, R. F. Carswell +1
Exploring the possibility that fundamental constants of Nature might vary temporally or spatially constitutes one of the key science drivers for the European Southern Observatory's…
Constraints on a special running vacuum model
Chao-Qiang Geng, Chung-Chi Lee, Lu Yin
We study a special running vacuum model (RVM) with , where , and are the model parameters and is the Hubble one. This RVM has non-ana…
