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. www.sciencedirect.com/referencewor... www.sciencedirect.com/science/arti...

Important educational lessons at the #PHISCC neutral hydrogen conference in Sardinia

After two talks, discussion sessions, and safaris at a conference, now in Cape Town for catching up with friends and some collab work next week (besides grant writing/responding to ref report...) Made a friend this evening too!

Very rude guests interrupted someone's conference talk today. They should have read the code of conduct! #HungryHIppos #Kruger

Astronomy conferencing when the power goes out #HungryHIppos #Kruger

Going back to South Africa today! Conference at Kruger, and then Cape Town Friday-Thursday. LMK if you wanted to catch up!

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. #timezones

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! 🫠

Treated #NAM2025 to a musical, rhyming 1-min sparkler talk this morning >:] Thanks to a particular tune from The Sound of Music...

This morning I gave a 1 min sparkler talk about a poster on FRBs and scattering correlations with host galaxy properties at #NAM2025 in Durham in person. This evening I gave a talk over telecon at #FRB2025 about a new repeating FRB discovery. That's right dual conferencing baybeeee

Also got to see my PhD student, Hugh Roxburgh, give his talk at #FRB2025! He was a perfect 12 hours time difference from that meeting in Montreal. Hugh's carrying on with HI follow-up of multiple FRBs - paper submission is soon!

Attending #NAM2025 this week - only arrived today but in Durham for the week. Seeing the castle shortly after getting off the train by the river was pretty neat. Got posters (plural) for this conference - first flash/sparkler talk tomorrow!

I put out a preprint recently! Investigated how FRB properties (such as scattering timescale and |RM|) we measured for 35 FRBs localised via ASKAP and the CELEBI pipeline (plus a few in the lit), correlated (or not) with global host properties. #FRB arxiv.org/abs/2506.23403

New repeating FRB! www.astronomerstelegram.org?read=17257

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. edition.cnn.com/2025/06/30/s...

Hot off the press - a new Nature @natureportfolio.nature.com paper by Ziteng (Andy Wang)! A new long period transient, this time with X-ray emission. Discovered as part of our ASKAP transient searches, it has a strong burst of radio emission every 44.2 minutes. #RadioAstronomy #AstroSci

I've been part of a large collaborative effort, featuring a bunch of CRAFT survey people, behind this discovery! A long-period radio transient (LPT - rare objects) detected in X-ray, the first for an LPT! Images by the lead author, Ziteng (Andy) Wang. #nature www.nature.com/articles/s41...

I, alongside my boss Romeel, have a Masters project being advertised through #DARA - the Development in Africa with Radio Astronomy program! Deadline is this Sunday - if you are/know a potential student from specific countries in Africa, check it out! www.dara-project.org/advancedprog...

Gave a seminar at St Andrews yesterday! Talked on a mix of FRB, HI with MeerKAT, and simulation work. Was a nice town to walk through after the work day was done too (helped the weather was nigh perfect).

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.)

Overleaf is down for the past half hour... nobody panic!

Watching the stream from the other side of the world. What a swing from 3 months ago #aus

Sent in my postal vote for the Aus election recently - took a bit to get here! Will be interesting to see how it goes...

How not to schedule recurring events

Spring arrived early for this tree compared to most around here

Gave a talk at work today about VR and using it for astronomy research and outreach! I like showing off that stuff.

Some good talks at the International Women's Day event held today at work. Involved some personal stories as well.

Shortly after I started my postdoc in Australia, September 2021, we applied for a partner visa for my wife. This week, in March 2025, she got the 2nd stage of the visa, over six months after we moved country for my next postdoc...

👀👀👀 Two exciting preprints today from Aussie institutions and scientists! 🔭☄️ 1. A 41-sec radio pulsar! Slowest pulsar we know about is ~23-secs and then there are these mysterious long-period transients that have rotations periods of mins to hours. This one fits between them!

Met a new friend during the walk home from work today

Hope: Now that I've submitted this grant app I can get back to research! Reality: A bunch of other tasks and emails that were neglected during grant writing needs attention first 😅

"I wish overleaf wasn't still down..."

'Hey is this thing on? How do I work this new video system...'

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.

The book chapter KG Lee and I wrote together has now been approved by editors of the Encyclopedia of Astrophysics! Cool that something I co-wrote will be part of a book (ignoring the thesis :v) 'Cosmology with FRBs' preprint now updated: arxiv.org/abs/2410.24072 #FRB #cosmology

New paper! Led by Ziteng 'Andy' Wang, I was part of a team that helped commission a new system for detecting fast radio transients. Looking forward to all the stuff ASKAP finds with CRACO! www.cambridge.org/core/journal...

Guess I will be WfH tomorrow - strong winds closing down the whole site, cancelling buses and trains, etc. Hope everyone in the UK stays safe tomorrow! Shout-out to my phone suddenly blaring an alarm, then me clicking okay to get it to stop yelling and the notice about the winds disappearing...

The 2nd ASymba paper has been accepted and is now on arxiv! Led by Mathieu Perron-Cormier, a PhD student who has been spoiled by a record time acceptance for a paper submitted before the holiday season kicked in... so kudos to the referee for the turnaround! arxiv.org/abs/2501.09547

An article by the first 2 authors of a cool discovery found with #ASKAP - a pulsar rotating every 6.5 hrs, way slower than usual. We also found it with CRACO which I helped commission. My first co-authorship in Nature Astronomy! :B Neat image by James Josephides. theconversation.com/blinking-rad...

Gave my talk at #DEX just before the lunch break - 5 minutes of discussing why MeerKAT is great for HI (follow-up or with serendipitous discoveries!)

Attending my first DEX! 2 day conference, in Newcastle. Been enjoying it so far. #DEX

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. =)
