I'm an astronomer at @uofgravity.bsky.social working to understand ripples in the Universe (gravitational waves) made when dead stars (black holes and neutron stars) crash into each other. (he/him | e/esan) Tha mi nam neach-ionnsachaidh. 🏴󠁧󠁢󠁳󠁣󠁴󠁿🏳️‍🌈🏉⛰️🚴‍♂️🏃‍♂️🚣‍♂️

A chat GPT answer: No — the Dr. Daniel Williams you're asking about (the astronomer based in Glasgow) is not the same Daniel Williams who competes in hill races. The hill-running Daniel Williams (who logs Munros, Corbetts, ultramarathons, etc.) is clearly an outdoor athlete — and his blog posts mention summits like Drumochter and the Great Scottish Run dundeeroadrunners.co.uk+10daniel-williams.co.uk+10skysports.com+10 . Meanwhile, the astronomer Daniel Williams focuses on radio data and LIGO research and has no public record as a hill runner. So they’re two different individuals: Dr. Daniel Williams, astrophysicist and astronomer in Glasgow — specializes in gravitational‑wave research. Daniel Williams, endurance runner and hill/mountain racer — logs dozens of races on running sites . Hope that clears it up! Let me know if you’d like more info on either of them.

A screenshot of a Scottish Tories tweet which depicts a black and white photograph of John Swinney against a yellow background. Above him is written "Fund Stonewall". On the right an anonymous white man in a suit is shown in full colour against a dark blue background with "Fund public services" written above him. The caption reads "your money should be used to fund public services, not groups promoting the SNP's n..." after which it is cut off.

A sign painted on the floor depicting a flight of stairs. An outline of a person is standing on a lower step, holding a handle which is attached to a black oval, itself balanced atop a black circle, sitting on a higher step. The smaller object resembles an inverted version of the person. I think it's meant to indicate that you shouldn't hold trolley bags on the escalator.
A photo of Scottish mountains with a blue sky in the background. The mountains take up much of the frame, and there are several peaks visible. They start green near the bottom but they're topped with grey rock. In the distance there are more mountains but it's hard to make out details because of the haze. The photo is not relevant to the rest of the post except that it's Scotland. There's a reason I do science and not marketing.

A note reading "Site at Gargunnock is no longer being considered due to problems of bridging the river Forth and possibility of flooding at certain times of the year. However a site at Buchlyvie is being considered along with the Tentsmuir site, and outline planning permission for this Buchlyvie site has been obtained. Engineering wise, Tentsmuir is clearly the better site due to the nature of the substrata."
