New research by OzGrav PhD student Paul Disberg and Chief Investigator Prof. Ilya Mandel (Monash University) explores how newborn neutron stars get a powerful natal kick — a supernova shove that launches them at hundreds of km/s!

Celebrating 10 Years of Gravitational Waves!

Last week, OzGrav hosted a two-day workshop at Swinburne to mark a decade since the first detection of gravitational waves, GW150914, a discovery that reshaped astrophysics and confirmed Einstein’s prediction.

Here’s to the next decade of discovery!

This happened 10 years ago, and it was weird!
GW150914 was the first ever detection of gravitational waves, when two black holes collided, sending ripples through space.

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.

OzGrav Associate Investigator Dr Simon Stevenson explains more in The Conversation:

10 years ago, gravitational waves changed astronomy. A new discovery shows there’s more to come
First, gravitational waves proved Einstein correct. Now, they’ve confirmed Stephen Hawking was right about black holes.

We recognise that this loss may be deeply felt by many in our community, particularly those
who had the privilege of working closely with Rai.

Our thoughts are with you during this time.

Rai was larger than life, continuing to make important contributions and provide invaluable
guidance and advice to postdocs and students right until the last month of his life. He always took the time to listen and encourage new ideas.

We are saddened to hear of the passing of Rai Weiss, whose vision and dedication
laid the foundations for gravitational-wave astronomy. Rai’s pioneering work and
steadfast commitment to science made LIGO possible, opening an entirely new
window on the universe.
