Thanks to @chrislovell.bsky.social and Sotiria Fotopoulou for organizing a fantastic SBI & Galaxy Evolution workshop, and inviting me to speak! Learned a ton and am so glad I got to finally visit the UK (and Bristol in particular). 🔭☄️🧪 #AstroSci

Will Handley going very easy on me in English Pool at one of our social hours

Very proud to be a part of this excellent review on "The Spectral Energy Distributions of Galaxies", part of the Encyclopedia of Astrophysics. Kartheik has made some absolutely stunning figures, example below. Go check it out! arxiv.org/abs/2502.17680

Fantastic work from Sophie, and some potentially big implications for the modelling of stellar populations in the early Universe..! Check out the models here, including some nice interactive notebooks to get you started: sophie-newman.github.io/cloudy-maras... #astronomy #extragalactic #astrocode

Beatrice Tinsley's Ph.D thesis, 1967. Has anything changed? :) (except maybe the uncertainties on primordial Helium abundance...) #astronomy #extragalactic #histsci

Quote from Beatrice Tinsley's Ph.D thesis. "The evolution of a galaxy should, ideally, be deduced by following its history either backwards in time from a known population of stars and gas, or forwards from primeval gas. The former method is not feasible because observable integrated features do not give enough details. The latter is also subject to great uncertainties, especially as to whether the primeval gas contained Helium (Peebles, 1966), and as to the nature of first generation stars."
