When two neutron stars collide, they shake spacetime and light up the cosmos in a brilliant flash called a kilonova. OzGrav researchers Dr Anais Möller, Dr Jade Powell and Dr Simon Stevenson explore how the Vera C. Rubin Observatory could help spot these rare events.

The upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time will detect an astonishing number of transients — including kilonovae from colliding neutron stars. aasnova.org/2026/02/04/h... 🔭🧪
Screenshot of tweet from the ARC saying they’ll announce DECRA and LIEF outcomes on Tuesday 25th Nov.
ARC says they’ll announce DECRA and LIEF outcomes tomorrow (Tuesday 25th Nov).
In recent times these announcements have been around 11am Canberra time. With 2 schemes on the same day, I assume they’ll announce one of them later in the day (probably DECRA first).
A portrait of Einstein and Hawking with a binary black hole in between. It is rather dramatic, and shows cool light-bending effects.

First, gravitational waves proved Einstein correct. Now, they’ve confirmed Stephen Hawking was right about black holes.

Ten years ago, we heard the universe rumble for the first time.
That first discovery proved Einstein right.
Now, a new gravitational-wave discovery let's us put Stephen Hawking's laws of black holes to the test

Ten years ago, we heard the universe for the first time. Now, we’ve heard it again... only louder.
OzGrav researchers, Neil Lu, PhD student at the Australian National University (ANU), and Teagan Clarke, PhD student at Monash University, explain!

A new gravitational wave event rocked detectors almost 10 years after the first detection. But this time, it was up to four times as loud thanks to a decade of upgrades.

We are excited to announce the discovery of #GW231123, a gravitational-wave signal from the merger of two high-mass black holes to form one about 190–265 times the mass of our Sun

The @ligo.org - Virgo - KAGRA Collaboration is happy to announce the detection of the merger of the most massive black holes ever observed with gravitational waves 🕳️🕳️
GW231123: Heaviest black‑hole merger yet detected in gravitational waves.
~100 M☉ + ~140 M☉ → ~225 M☉ remnant, spins near physical limit.
“This blip forces us to rethink how very heavy, rapidly spinning black holes come to be.” – Prof Eric Thrane

Researchers at ICRAR & OzGrav, together with an international collaboration, have identified ASKAP J1832-0911—a long-period transient that emits 2-minute pulses in both radio and X-ray wavelengths every 44 minutes.
Results published in Nature.

So the Department of Physics at the University of Auckland is looking to hire a lecturer/senior lecturer in one of the following areas:
- Physics education research,
- Quantum optics and quantum information,
- Biophotonics and/or medical physics,
- Astrophysics and/or space technology.

Guardian Australia @australia.theguardian.com reporting on the proposed changes to the ARC grants system.
There’s concern that getting rid of standalone fellowships will have lots of unintended consequences, especially for Early-Career Researchers.

Detailed Assessor reports are now available in RMS and rejoinders have opened.
Here’s an older thread with suggestions on dealing with assessor reports – especially the #ARC3DayRule – and constructing a rejoinder.
