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 🧵👇 🔭📡

As part of a collaboration between PhD students, these observations were taken with Murriyang (CSIRO Parkes radio telescope) and verified with South Africa's MeerKAT. Check out the feature article: www.spaceaustralia.com/feature/disc... 📸 Mandow et al. 2026 #SpaceAustralia #RadioAstronomy 🔭🧪📡
Plot with two vertical tiles, each tile representing data from Parkes and the MeerKAT telescope. On the x-axis is pulse phase and on the y-axis is time. Both telescopes report the profile change event features in unison.Three-panel image. Two small square panels on the left side show the eigenprofile of the principal component for two telescopes. It features a sharp narrow peak and two smaller narrow troughs on either side. The larger third panel on the right plots the data points as a function of time on the x-axis and normalised PC score on y-axis. The curves start with a gradual recovery then suddenly dip before slowly recovery back exponentially too.

J0437 is the brightest and closest MSP to Earth. Both events altered the same profile components in the same way and followed a similar evolution over time, exhibiting frequency dependence and affecting polarisations. 📸 Mandow et al. 2026 #SpaceAustralia #RadioAstronomy 🔭🧪📡
Plot with pulse phase on x-axis and flux density in milliJansky on y-axis. Inside the plot are eight curves, colour-coded to represent different frequency bands, showing the pulsar profile. Three columns are shaded pink, grey and purple, indicating the different regions of the profile that were affected by the profile change.Plot with two tiles showing pulse phase on x-axis and polarisation positin angle on y-axis. Plotted are the PA of the template and three dates, showing the onset date shifting the PAs in the specific region of the profile.

New research from @monashastro.bsky.social @ozgrav.bsky.social has shown that some stars live young, burn bright, then just blow themselves up! ⭐💥 Article and graphics by @astronerdika.bsky.social www.spaceaustralia.com/news/black-h... 📸 S. Galaudage #SpaceAustralia
Infographic titled “Pair-Instability Supernova,” with the subtitle “how very massive stars can destroy themselves completely.” Three illustrated panels show the process from left to right. In the first panel, “Pair Production,” high-energy photons inside a massive star create electron–positron pairs, shown in a zoomed-in bubble, draining pressure support from the core. In the second panel, “Core Contraction,” the star’s core contracts and heats up as radiation pressure can no longer balance gravity. In the third panel the star has blown itself up with the world "Total Disruption" below it.

The facility was built on the lands of the Wotjobaluk, Jaadwa, Jadawarjali, Wergaia, and Jupagulk peoples, and we are proud to acknowledge their continued custodianship of these lands and waters. The facility was funded with the support of the Australian Government and the Victorian Government. The facility was constructed with the support of the Stawell Gold Mines.

The results of a four-year analysis on PSR J1713+0747 have indicated that the millisecond pulsar underwent a significant profile change event, whose origin can be traced to the magnetosphere of the star - with massive disruptions to the polarisation. #SpaceAustralia 📸 @cosmicrami.com 🔭🧪📡
Plot showing three rows and eight column grid. The rows represent the stokes parameters, and the columns represent different frequency bands. The data in the plots shows the profile residuals per band per stokes.Three panels. Y-axis is normalised flix density, and x-axis on each is pulse phase. There are eight curves per panel, coloured individually and each representing a different frequency band. The left panel is the template and the remaining two panels are 50 days post event and 2 years post event. In the middle panel, three red arrows indicate regions of the profile that are affected by the change.
