Cosmic Ripples in Space and Time: Largest Number of Gravitational Wave Detections to Date
Key points: An international team of scientists, including Australian researchers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), have collaborated on a…
Investigating the Spins of Binary Black Hole Mergers To Uncover How They Formed and Evolved
With the growing catalog of binary black hole mergers, researchers can study the overall spin properties of these systems to uncover how they formed and…
Exploring the Mysterious Origins of Extreme Cosmic Light Flashes That Outshine Entire Galaxies
Our Universe shines bright with light across the electromagnetic spectrum. While most of this light comes from stars like our Sun in galaxies like our…
The Aftermath of Binary Neutron Star Mergers: What Remains Behind?
On August 17th, 2017, LIGO detected gravitational waves from the merger of two neutron stars. This merger radiated energy across the electromagnetic spectrum, light that…
Exploring Common Envelope Outcomes of Binary Stellar Evolution
Binary neutron stars have been detected in the Milky Way as millisecond pulsars and twice outside the galaxy via gravitational-wave emission. Most of them have…
Bayesian Inference for Gravitational Waves From Binary Neutron Star Mergers in 3G Observatories
In the 2030’s, gravitational-wave detectors will be thousands of times more sensitive than Advanced LIGO, Virgo, and KAGRA. The network of “third generation” (3G) observatories…
Probing Mysterious “Afterglow” X-Ray Remnants From Extreme Cosmic Bursts of Light
Short gamma-ray bursts are extremely bright bursts of high-energy light that last for a couple of seconds. In many of these bursts, there is a…
Pulsar Timing Array Explores Mystery Gravitational Waves From Supermassive Black Holes
Galaxies host supermassive black holes, which weigh millions to billions of times more than our Sun. When galaxies collide, pairs of supermassive black holes at…
An Interactive Science Exhibit Based on a Real-Life Gravitational-Wave Detector
Making Waves at the Museum Exhuibit modeled after a real-life gravitational-wave detector to explain gravitational-wave science. It was developed by an international team, which includes…
Supernova Explosions in Dense Active Galactic Nuclear Discs
‘Type Ia’ supernovae involve an exploding white dwarf close to its Chandrasekhar mass. For this reason, type Ia supernova explosions have almost universal properties and…
Optical Observations of BepiColombo Spacecraft as a Proxy for a Potential Threatening Asteroid
BepiColombo is a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) designed to study the planet Mercury. Launched…
Gamma-Ray Bursts – Bright Cosmic Explosions – Could Reveal Strange Interstellar “Knots”
Gamma-ray bursts are enormous cosmic explosions and are one of the brightest and most energetic events in the Universe. Their brightness changes over time, illuminating…
Blistering Stars in the Universe: Rare Insights Into How Violent Supernova Explosions Affect Nearby Stars
What happens if a supernova explosion goes off right beside another star? The star swells up, which scientists predict as a frequent occurrence in the…
Spinning Neutron Stars Reveal New Insights Into Elusive Continuous Gravitational Waves
Five years on from the first discovery of gravitational waves, an international team of scientists, including from the ARC Centre of Excellence for Gravitational Wave…
Deciphering the Lives of Double Neutron Stars Using the Ripples in the Fabric of Space and Time
