The stochastic enrichment of Population II stars
Louise Welsh, Ryan Cooke, Michele Fumagalli
We investigate the intrinsic scatter in the chemical abundances of a sample of metal-poor ([Fe/H]<-2.5) Milky Way halo stars. We draw our sample from four historic surveys and focu…
A limit on Planck-scale froth with ESPRESSO
Ryan Cooke, Louise Welsh, Michele Fumagalli +1
Some models of quantum gravity predict that the very structure of spacetime is `frothy' due to quantum fluctuations. Although the effect is expected to be tiny, if these spacetime…
A bound on the 12C/13C ratio in near-pristine gas with ESPRESSO
Louise Welsh, Ryan Cooke, Michele Fumagalli +1
Using science verification observations obtained with ESPRESSO at the Very Large Telescope (VLT) in 4UT mode, we report the first bound on the carbon isotope ratio 12C/13C of a qui…
