Radio astronomer at the Uni of Edinburgh. Has a moustache.
A while ago I co-wrote a book chapter with Prof Khee-Gan Lee - as of last week the book got published! It's in the Encyclopedia of Astrophysics, and the chapter is about doing cosmology with fast radio bursts.

Gave a talk at Dynamic Radio Sky last night! About our findings with scattering correlations for FRB host galaxies. I really do mean 'last night' - it was 12:30am for me... and probably the best possible time given the schedule! Better than not being able to give the talk at all.

Jumped from double conference week into double telescope proposals deadline day (albeit one got led by my student in the end, and neither of them were started from scratch). Hoping next time MeerKAT and GMRT won't conspire to have their deadlines on the same day! 🫠

The paper came out only in the past day, but the preprint was on arxiv last week. Despite no PR planned, it randomly got picked up, including by CNN... and all because we found a satellite rather than what we were trying to detect. But that's cool too.

Long-dead satellite emits strong radio signal, puzzling astronomers | CNN
A NASA satellite that’s been orbiting as space junk since 1967, Relay 2, emitted an unexpected, powerful radio burst that astronomers initially struggled to explain.

If I had a nickel for every time I saw a fire near a uni building I worked at, I'd have two nickels. Which isn't a lot, but it's weird that it happened twice, right? (This one was fine, unless you're small patches of vegetation. But not something I expected to see in Scotland! Thanks firefighters.)

Biased/biases/etc have surely come up in work I've done because that's a common phrase to use about previous studies, samples, etc. Similarly for 'excluded' (we excluded ___ from the sample). Amazingly terribad.

Hi world! Belatedly making one of these. Idk how active I'll actually be but might as well try this place out. I'm Marcin, a postdoc working in Edinburgh, and previously worked in Aus and South Africa, on radio astronomy (HI, FRBs) and simulation (Simba) things. =)
