Description
Accurate atomic data are a cornerstone of astrophysical research - vital for interpreting the spectral analyses that drive our understanding of the Universe. Despite their importance, much of the atomic database (especially for elements beyond the iron group) remains based on measurements from the 1960s or earlier, which now fall far short of current, high-accuracy demands. The weakest link in modern astronomical spectral analyses is often poor quality atomic data, and at least order-of-magnitude improvements in accuracy are urgently needed. With the next generation of telescopes and surveys on the horizon, these demands are only set to increase.
The astronomy community often assumes that there are vast numbers of researchers dedicated to measuring these vital atomic data – unfortunately there are not! The number of researchers conducting these crucial experiments has been steadily decreasing, without younger researchers to replace them. This diminishing expertise poses a grave threat to the future of the field - once lost, it will be impossible to meet the growing demands of modern astrophysics. The recent closure of the two leading institutes for experimental atomic spectroscopy in the United States only underscores this precarious future for the field.
This talk will give an overview of the current state of atomic data for astrophysics and explore ongoing efforts to secure the future of the field. With the right support, the UK is ideally positioned to extend its leading role in experimental atomic spectroscopy, ensuring that we remain at the forefront of astrophysical discovery for decades to come.
