Two new papers have used data from JWST and ESO's VLT to help uncover new details of the chaos amongst the stars: Apep

@rami.spaceaustralia.com spoke with one of the paper's lead authors @astroryan.bsky.social about this incredible system.

For only the third time ever, a glitch event has been observed on a millisecond #pulsar.

@rami.spaceaustralia.com chats with lead author and PhD candidate Bhavnesh Bhat about the significance of this important, yet rare, event.

One of astronomy's most inspiring figures, Dame Prof. Jocelyn Bell Burnell was in Sydney this week.

@cosmicrami.com sat down for an interview with her, discussing the impact of her discovery and community advocacy legacy.

But is PSR J1713+0747 the only millisecond pulsar with profile variability? And what are the implications of this for high-precision timing experiments, such as searching for gravitational waves?

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.

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.

This new study, from Dylan Grigg at Curtin University, is not the first to study the impacts of Starlink on #RadioAstronomy, but is the largest of its kind and quantifies how this type of radio frequency interference - that comes from above - will impact the mega-science SKA project.

Radio frequency interference from Starlink not only spans the narrowband intended emissions but also broadband unintended emissions, coming from propulsion and avionics.

This RFI is unregulated and affects key science goals.

Starlink can appear in ~30% of all sky images.

📸 Grigg et al. 2025

📡🔭
Plot with frequency on the X-axis (ranging from 73 - 234 MHz) and the percentage of images in which a Starlink satellite was identified. The plot also shows the median noise in the data set for each frequency band. The results show that in certain bands, between 150 - 200 MHz there is significant contamination from Starlink satellites.

What makes ASKAP J1832-0911 stand out from the rest of the Long-Period Transients is that, for the first time, coincident X-ray emission, along with radio emissions, have also been detected from such an object, thanks to the Chandra X-ray Observatory.

The bottom tile represents the signal in x-rays, and presents as more broader peaks that have extended features. The peaks for both radio and x-rays occur at the same phase

Aintoff projection map showing the entire sky as a function of galactic longitude and latitude. Overlaid on the oval-shaped map are contour lines that have a colour range of deep blue to white-blue. Also overlaid are several stars of different sizes, which represent the pulsars. There is a bright contour region near the southern pole. The text on the image reads: “This spot is brighter than the rest of the map!” and points to the bright spot. There is also a side note, that says “Note, the statistical significance of the hot spot is too low to claim a definite detection. The message this plot is conveying is that there is potentially an interesting signal in the southern hemisphere that seems brighter than the rest of the sky.
