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).

Couple of neat new FLARES papers out recently, including predictions for LISA from supermassive black hole mergers in the early Universe from the amazing Shihong Liao!

First Light And Reionization Epoch Simulations (FLARES) -- XIX: Supermassive black hole mergers in the early Universe and their environmental dependence
The upcoming space-based gravitational wave (GW) observatory, LISA, is expected to detect GW signals from supermassive black hole (SMBH) mergers occurring at high redshifts. However, understanding the...

Lol okay this one is legit good. A galaxy detected at a possible redshift of 21,380

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!

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...

Beatrice Tinsley's Ph.D thesis, 1967. Has anything changed? :)

(except maybe the uncertainties on primordial Helium abundance...)
