Was great to work with Stefano Sotira (PhD student at Uni of Bologna, currently looking for a postdoc position) and co. on this paper, simulating cold gas formation due to jet feedback in galaxy clusters!

I'm happy with the release in Dev - Looking good. Just spinning up a staging environment on AWS now. If it passes the tests (may need a tweak here and there), I'll promote to production. #AstroCoding
Here's a quick progress update on Lunar Eclipses: Much testing and fixing has been done, but this now shows on my development server😎I've still a bit of testing i'd like to do, but I'll be staging this next week and publishing live in time for the Eclipse on Friday #AstroMethods #AstroCoding

Our paper, led by Giulia Ortame (PhD student @cambridgeastro.bsky.social), is up on the arXiv today. Here, Giulia explores simulations following the growth of low-mass black holes in dwarf galaxies using different accretion and feedback models.

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! 🎉

Unit tests running OK-boring part of the project if I'm honest, but nice to have an early warning system for future code changes

Just adding some bells and whistles to the map interface.

Most likely to deploy the ISS ground tracker with planetary alignments next weekend
