Identifying primordial ripples would be key to understanding the conditions of the early universe. In the moments immediately following the Big Bang, the very first…
PRISMA+ scientists propose exotic low-mass fields as new messengers of astrophysical events. Cataclysmic astrophysical events such as black hole mergers could release energy in unexpected…
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…
New analysis of gravitational-wave data leads to wealth of discoveries. An international research collaboration including Northwestern University astronomers has produced the most detailed family portrait…
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…
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…
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…
When two neutron stars slam together, the result is sometimes a black hole that swallows all but the gravitational evidence of the collision. However, in…
By quieting the quantum whisper, we can now listen to the more subtle notes of the cosmic symphony. Gravitational wave detectors have opened a new…
How fast is the universe expanding? We don’t know for sure. Astronomers study cosmic expansion by measuring the Hubble constant. They have measured this constant…
Through simulations of a dying star, a team of theoretical physics researchers have found the evolutionary origin and the maximum mass of black holes which…
The most massive black hole collision ever detected has been directly observed by the LIGO and VIRGO Scientific Collaboration, which includes scientists from The Australian National University (ANU). The…
Researchers suggest a novel process to explain the collision of a large black hole and a much smaller one. A lopsided merger of two black…
A binary black hole merger likely produced gravitational waves equal to the energy of eight suns. For all its vast emptiness, the universe is humming…
Scientists Detect First-of-Its-Kind ‘Intermediate-Mass’ Black Hole An international research collaboration including Northwestern University astronomers has witnessed the birth of an “intermediate-mass” black hole. This is…
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…
