Spectral shape corrections for SDSS BOSS quasars

Dinko Milaković, John K. Webb, Chung-Chi Lee +1

Modifications were made to the Sloan Digital Sky Survey's Baryonic Oscillations Spectroscopic Survey (SDSS/BOSS) optical fibres assigned to quasar targets in order to improve the s…

Non-uniqueness in quasar absorption models and implications for measurements of the fine structure constant

Chung-Chi Lee, John K. Webb, Dinko Milaković +1

High resolution spectra of quasar absorption systems provide the best constraints on temporal or spatial changes of fundamental constants in the early universe. An important system…

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…
