An awesome paper by Ivey showing that maybe we need to think harder how we plan our observations when chasing after Solar-like bursts from active stars

Ivey Davis@iveydavis.bsky.social · 5d ago

I submitted this on arXiv and then immediately got the flu, but now that I can sit upright again, my first single (!?) author paper was accepted: arxiv.org/abs/2609.16911 TLDR: we might be doing ourselves dirty by focusing on very active stars to find plasma emission at low frequencies (<<1GHz)

I'm finally so excited to share this! My second PhD paper, and what I've spent the last year working on ... We've discovered not one, BUT TWO, profile change events on the closest and brightest millisecond pulsar (MSP) to Earth! www.spaceaustralia.com/feature/disc... Let's jump ito a 🧵👇 🔭📡

Are millisecond Pulsars, nature's cosmic clocks, as stable as we once thought? A new study by @rami.spaceaustralia.com has reported the discovery of two consecutive profile change events on PSR J0437-4715. www.spaceaustralia.com/feature/disc... 📸 NASA SVS #SpaceAustralia #RadioAstronomy 🔭🧪📡

The future of low frequency radio astronomy is space! It is only in space that we can unlock the last part of the electromagnetic spectrum that has yet to be explored. I am fortunate to play a minor part in this team lead by Joe Lazio for the MegaWave Radio Surveyor space mission.

I find it amusing that I am now teaching Introduction to Programming for Astronomy and Astrophysics with Python at the University of Amsterdam... When I was never taught how to program in my uni degree (had to entirely self-learn). May God have mercy on the students.

Rarely in radio astornomy are results tested against conditions in a lab. However, the team out of Palo Alto have done the best job yet of creating the conditions of a solar coronal mass ejection in a lab. Fun result written up by @econover.bsky.social www.sciencenews.org/article/star...

Stars’ plasma spurts may be blocked by magnetic fields

The sun frequently flings plasma into space, but sightings of such eruptions on other stars are rare. Magnetic fields could explain why.

I am beyond excited about what the SKA Observatory will reveal to us about stars, planets, and whether life could be out there. The chapters written by the Cradle of Life Science Working Group really emphasises how much SKAO will be a game changer in astronomy.

Very happy to advertise a Postdoctoral Research Associate in Exoplanet Science position with me and Christian Schwab at Macquarie University in Sydney. We'll be working on applying machine learning & differentiable physics models to extremely precise radial velocity surveys.
