‘Eta Carinae’ is an extraordinary star that has fascinated mankind for decades. It’s surrounded by an expanding ‘Homunculus nebula’, shaped like an hourglass. This nebula…
Distant galaxies used as ‘locator pins’ to detect ‘invisible’ gas cloud. Half of the universe’s matter is ‘missing,’ but PhD student Yuanming Wang has developed…
Astronomers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) and CSIRO have just observed bizarre, never-seen-before behavior from a ‘radio-loud’ magnetar—a rare…
The merger of two black holes in a binary system emits energy that can be detected on Earth by gravitational-wave observatories. The LIGO Scientific Collaboration…
A group of international scientists, including an Australian astrophysicist, has used know-how from gravitational-wave astronomy (used to find black holes in space) to study ancient…
In 2015, the first direct observation of gravitational waves was made by the Advanced Laser Interferometer Gravitational-wave Observatory (aLIGO) (Abbott et al. 2016). The detected…
Over the past five years, astronomy has been revolutionized as scientists have used ripples in the fabric of spacetime, called gravitational waves, to reveal the…
In a recently published study, a team of researchers led by the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) at Monash suggests an…
The Advanced Laser Interferometer Gravitational-Wave Observatory (Advanced LIGO) detectors and the Virgo detector have directly observed transient gravitational waves (GWs) from compact binary coalescences. After…
Rapidly rotating, asymmetric neutron stars that undergo free precession can produce both modulated pulse signals and continuous gravitational radiation with characteristic features, and thus are…
Massive stars end their lives with energetic explosions known as supernova explosions. ‘Stripped-envelope supernovae’ show weak or no traces of hydrogen in its ejecta, meaning…
A team of gravitational-wave scientists led by the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) reveal that when two black holes collide and…
A new study has developed an innovative method to detect colliding supermassive black holes in our Universe. The study has just been published in the Astrophysical…
Massive stars are larger than about 10 times the mass of the Sun and are born far less often than their low mass counterparts. However,…
A new study makes a compelling case for the development of “NEMO”—a new observatory in Australia that could deliver on some of the most exciting…
Gravitational waves are ripples in space-time that come in many forms. So far, short-duration gravitational wave signals have been observed from colliding black holes and…
A cutting-edge vibration sensor may improve the next generation of gravitational-wave detectors to find the tiniest cosmic waves from the background hum of Earth’s motion….
On March 12th, 2020, a space telescope called Swift, detected a burst of radiation from half-way across the Milky Way. Within a week, the newly…
