ALMOST DARK GALAXIES ARE JUST CLASSICAL DWARF SPHEROIDAL GALAXIES. WE EXPECT TO FIND THEM EVERYWHERE. THEY DON'T NEED A NEW NAME. ALSO THEY'RE ACTUALLY QUITE BRIGHT. This has been a public service announcement. 🔭🧪☄️

Early dark energy - like regular dark energy - is not something I really understand! But I enjoyed talking about this paper on its potential effect on large scale structure in our latest episode. Tune in to learn more, or check out the paper! arxiv.org/abs/2608.17212

This paper offered up a neat test of Chandrasekhar's dynamical friction formula in clumpy disks. Given observations of clumpy disks at high redshift, it seems pretty relevant and cool. Check out our latest episode on starxiv.com for more! 🔭🧪☄️

There's actually research on this and it involves scrutiny. If you're Black people are going to look at your work looking for mistakes in a way they would never for white people.

Black Workers Really Do Need to Be Twice as Good
African American employees tend to receive more scrutiny from their bosses than their white colleagues, meaning that small mistakes are more likely to be caught, which over time leads to worse perform...

From yesterday's ☀️🌕🌍 event on the university campus! Taken with my seestar. It starts out a bit wobbly and occasionally the eclipse is eclipsed by our guests, but it is stable for the peak 🔭🧪🥰

Our not entirely sanctioned event became a wholly sanctioned success 🤩🔭🌍🌕☀️. It was amazing thanks to the support of all our Surrey astro team 🥰
Here we see the moon eclipsing most of the sun using our seestar telescope. Only a Cheshire smile remains of the sunAm image of the crowd on campus. Many people looking up to the sun which is on the right hand side. In the background you can just make out the Guildford cathedralHere we gaze upon a group of runners. They have their back to us as they look up at the eclipseAnother photo of the crowd as they wait for the eclipse

So, while LLMs are super helpful at coding, I maintain they are more like theorists than observers. My two pieces of evidence are: 1) when we are dealing with data, if it can't get something quite right, it blames the data quality and I have to convince it that it isn't the data 🔭🧪

No! Jodrell Bank is such an important site for UK astronomy and has such history. I remember well my visits and experiments there as a Manchester undergraduate. These cuts are short-sighted and I hate them. www.bbc.co.uk/news/article... 🔭☄️🧪

At today's UKRI board meeting, the fate of UK particle physics and astronomy will likely be decided. Have we done enough to convince the powers-that-be to halt the proposed funding cuts? 🤞 Read Prof. Hiranya Peiris in Nature today eloquently explaining why these cuts are wrong.🧪🔭⚛️ 📖: rdcu.be/friwM
Restructuring research funding as a choice between discovery and application gets the economics wrong, the evidence wrong and the people wrong.

A premise is gaining traction in science policy on both sides of the Atlantic: that fundamental and applied research are competing claims on the same budget, and that the balance must shift towards application. In the USA, the current administration has proposed cuts of billions of dollars to the National Institutes of Health and the National Science Foundation. In the UK, the national funding agency UK Research and Innovation (UKRI) is restructuring its portfolio around government growth priorities, with curiosity-driven research nominally protected but the grant lines that actually fund investigators under severe pressure. The language varies — ‘doing fewer things better’, ‘aligning research with industrial strategy’ — but the underlying logic is the same. Fundamental science, the argument goes, is a luxury that becomes dispensable when budgets are tight. This premise is wrong, and the consequences of acting on it are already visible.

This is * insane *. STFC council minutes from December have been removed from their website, changed, and reposted. The new version rolls back on funding commitments made explicit in the initial version. I can't think of another adjective other than Trumpian behaviour.
