The 🌕 has some pretty wild craters on it! This shows the maps that are stored to render surface lighting for any ray direction. Red is the horizon map, shown summed for all directions simultaneously, and blue is the normal surface deviation map.

It turns out that rendering bumpy surfaces is tricky! This is the same view as yesterday's post, but notice that the terminator detail looks different. It's the same underlying photographic texture, but can you tell what I improved? Solution in 🧵👇

A cool new paper led by Stephanie Buttigieg (PhD Student @cambridgeastro.bsky.social) is on the arXiv!
We compare GWB predictions from the FABLE simulation to NANOGrav's 15yr data, finding that they agree pretty well (1–2.5σ tension). Great work, Stephanie! 🎉
