Essentially we found a flash of X-rays that lasted a few days and then just stopped. Then it came back again. Then it stopped again. We believe this is a Sun-like star being slowly eaten up, 3 Earth masses at a time, by a 100,000 solar mass black hole.

A bit more info: in June 2022, my new LSXPS system developed at @uniofleicester @PhysicsUoL , using @NASASwift data, discovered a new transient. It turned out awesome. Paper out today, and see: or or

I am giving a talk at @NottinghamAstro this evening and looking at the traffic it seems that loads of people are on their way to hear it. Or possibly going to the Download Festival at Donningtom, but probably coming to hear me. right. ? 🤔.

10 years ago today, Swift detected what was then one of the brightest GRBs ever seen. It has today marked the anniversary by detecting. a fairly dull burst :)

You can still listen at Starts around 07:11 / 12 ish.After that I believe it will be on catch up for 29 days. And yes, I am a confessed X-ray pyromaniac, as @sherwoodobs can tell you!.

Just done a live interview about the "BOAT" GRB 221009A, for Radio Leicester - good fun, a really lovely interviewer, and an opportunity to give the wider picture of the awesome space work we do here in @PhysicsUoL at @uniofleicester and @SpaceParkLeic.

Oh, and I had a chat with @ITVCentral as well: And I believe I'll be talking live (gulp) on @BBCLeicester early tomorrow morning. So it's been a busy day!.

Also covered by @BBCNews: .Obviously, our PR focuses on the Leicester involvement, but many teams across the world have been working on this GRB, with many different facilities' data.

There's a press conference live from Hawaii right now: And the @uniofleicester @PhysicsUoL PR is here: Of course, ours is rather Leicester-centric, but, inexplicably, @NASASwift is rather undersold by the NASA PR so it evens out :).
