Fundamental Physics with ESPRESSO, Constraining a simple parametrisation for varying $α$

Vitor da Fonseca, Tiago Barreiro, Nelson J. Nunes +24

The spectrograph ESPRESSO recently obtained a limit on the variation of the fine-structure constant, $α$ , through measurements along the line of sight of a bright quasar with a pre…

Fundamental physics with ESPRESSO: Precise limit on variations in the fine-structure constant towards the bright quasar HE 0515 $-$ 4414

Michael T. Murphy, Paolo Molaro, Ana C. O. Leite +40

The strong intervening absorption system at redshift 1.15 towards the very bright quasar HE 0515 $-$ 4414 is the most studied absorber for measuring possible cosmological variations…
