Yesterday I gave my first PhD talk at the Astronomical Society of Australia’s Annual Science Meeting on my fav millisecond pulsar - PSR J1713+0747.

The pulsar that threw a tantrum!

Millisecond pulsars are used in pulsar timing arrays as they’re considered stable rotators over the long term. That is vote to helping us search for gravitational wave backgrounds - the big news that we announced last week.

But this very well know millisecond pulsar decided to undergo a massive magnetospheric reconfiguration in 2021 - only the second millisecond pulsar that we know off to exhibit this strange behavior!

In my PhD I will be exploring to see why this happened and if other millisecond pulsars might be doing this on a smaller scale. Maybe they’re not so stable after all … ask me again in three years!

Did you know, we have a detector the size of the Galaxy?! But what the heck can we use it for?

Well, we're looking for the gravitational wave background, and we're using pulsars to do it!

In part three of this series, I take a dive into what Pulsar Timing Arrays are, some of the challenges they face & how they can improve their sensitivity.

There's a dull roar that rumbles across the Universe: the gravitational wave background (GWB).

In part two of this special series, I dive into what the GWB is, what happens when Arrays around the world will finally make the first detection of this yet-to-be-discovered signal, and how it fits into the wider gravitational wave spectrum.

Am so very excited for this series of four feature articles, coming out over the next couple of weeks - have worked really hard on these!

Diving into my fav cosmic objects - pulsars - but also how we are using them in our pulsar timing experiments to look for the gravitational wave backgrounds.

🚨 Kerp your eyes on these articles! 🚨

Part 1 👇🏼

I also realised I have written A LOT about and for !

14 feature-length articles (2K - 3K words) where I have interviewed Australian astronomers working in the field to share their research.

The pulsar topics include gravitational waves, pulsar timing arrays, spider pulsars, pulsar planets, glitches, relativity, history and more!
