HIGHLIGHTS
- who: da Fonseca Vitor et al. from the Instituto Astrofu00edsica do Espau00e7o, Universidade Lisboa, Campo Grande, Lisboa, INAF, Osservatorio Astronomico Trieste, via GBTiepolo, Trieste, Italy have published the research work: Fundamental physics with ESPRESSO: Constraining a simple parametrisation for varying u03b1, in the Journal: (JOURNAL)
- what: The aim of this work is to constrain these parameters with both astrophysical and local probes. The authors take account of the first precise ESPRESSO measurement with LFC calibration (Murphy et_al 2022), as the main motivation of the present paper, from z=1.151 towards HE0515-4414.
