Detection of X-ray emission from a bright long-period radio transient - Nature A long-period radio transient with coincident radio and X-ray emission and observational properties unlike any known Galactic object has been observed by the Australian Square Kilometre Array Pathfind...

A team effort including @manishacaleb.bsky.social , @colourfulcosmos.bsky.social , @elenchically.bsky.social , @astrolaura.com , @funfactscience.com , @astromelow.bsky.social , @astromarcin.bsky.social , and more!

Hear from Joshua, the first author of the latest ASKAP discovery! Interviewed by Dr Kirsten Banks for @ozgrav.bsky.social 🌟🔭🧪

The emission of interpulses by a 6.45-h-period coherent radio transient - Nature Astronomy Coherent radio emission with a long (nearly 6.5 h) period has been detected from both magnetic poles of a rotating compact object, offering insights into the evolution and emission mechanism of compac...

This object was discovered by @elenchically.bsky.social and investigated by PhD student Yu Wing (Joshua) Lee and @manishacaleb.bsky.social, you can read the full paper here: www.nature.com/articles/s41...

Blinking radio pulses from space hint at a cosmic object that ‘shouldn’t exist’ The slowest ‘cosmic lighthouse’ ever found challenges our understanding of how neutron stars work.

Check out this new cosmic weirdo discovered using @csiro.bsky.social's ASKAP telescope! It spins so slowly that you could watch both the Fellowship of the Ring and the Two Towers and still have time leftover before it finishes a full rotation

It's got some pretty weird properties:

* Slowest period of a neutron-star like object so far - spins once every 6.5 hours.

* Changes brightness by 95% in minutes

What could be powering this unusual source?

Hot off the press!

One of my students, Yu Wing (Joshua) Lee, has discovered a new radio transient (along with @manishacaleb.bsky.social).

The Rapid ASKAP Continuum Survey (RACS) VI: The RACS-high 1655.5 MHz images and catalogue We have conducted a widefield, wideband, snapshot survey using the Australian SKA Pathfinder (ASKAP) referred to as the Rapid ASKAP Continuum Survey (RACS). RACS covers $\approx$ 90% of the sky, with ...

The latest data release for the Rapid ASKAP Continuum Survey (RACS), this time at 1655.5 MHz. Here's the paper describing the RACS-high images and catalogue. You can find links to the data products in the paper: arxiv.org/abs/2501.04978

Fantastic to see Carl’s #SciArt take out the Nature Astronomy cover of the year! 🔭🧪📡

The image shows one of our ASKAP antennas with a half pulsar, half white dwarf and is related to the weird yet growing population of long period transients: www.spaceaustralia.com/feature/popu...

Woo! 🎉 ASKAP on the @natureastronomy.bsky.social cover of the year! 📡 Amazing cover by Carl Knox and paper by Manisha Caleb, Emil Lenc and others 👏🎉

For an accessible write-up: theconversation.com/a-strange-in...

Congratulations to Manisha Caleb, Emil Lenc (@elenchically.bsky.social) and Carl Knox (@ozgrav.bsky.social) for winning cover of the year for Nature Astronomy!

Cool paper about a new long period transient discovered using ASKAP:

Fantastic to see a wide variety of EVs coming to (or already on) the market here in Oz. Also pleasing that the vast majority of them don't have an unpleasant Musky odour associated with them!

Cover of Nature Astronomy magazine. Artist illustration of a radio telescope pointing uopwards towards the sky. The background is divided into two halves. On the lect is the pulsar, with chaotic magnetic field lines emanating from it. On the right is a white dwarf star. In both backgrounds, there is plenty of stars. The words "pulsar-like or pulsar-unlike?" annotated.

YEAH! Look at the cover art on Nature Astronomy!

This wonderful #SciArt is made by Carl Knox (Swinburne/OzGrav), who makes all the awesome visual representations for astrophysics teams.

It's related to the story on the emerging weirdo long-period objects: www.spaceaustralia.com/index.php/fe...

I've made a starter pack for radio astronomers (and radio telescopes!). Let's build our radio community. Ping me if you would like to be added.

This one is an absolute monster in radio!
