Simonnet Scientists from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) have described a way to determine the birth population of double neutron stars — some of the densest objects in the Universe formed in collapsing massive […]

ANIMATION Scientists of the PRISMA+ Cluster of Excellence analyze data from the gravitational wave observatory NANOGrav. The NANOGrav Collaboration recently captured the first signs of very low-frequency gravitational waves. Prof. Pedro Schwaller and Wolfram Ratzinger analyzed the data and, in particular, considered the possibility of whether this may point towards new […]

An artist’s impression of two black holes about to collide and merge. 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 and the VIRGO Collaboration have announced tens of confident detections of such mergers to date. […]

Credit: Steve Gschmeissner/Science Photo Library 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 marine fossils as a predictor of climate change. The research, published in the journal Climate of the Past, […]

This illustration shows the NANOGrav project observing cosmic objects called pulsars in an effort detect gravitational waves – ripples in the fabric of space. The project is seeking a low-level gravitational wave background signal that is thought to be present throughout the universe. Credit: NANOGrav/T. Klein An international team of […]

Scientists have used a “galaxy-sized” space observatory to find possible hints of a unique signal from gravitational waves, or the powerful ripples that course through the universe and warp the fabric of space and time itself. The new findings, which appeared recently in The Astrophysical Journal Letters, hail from a U.S. and […]

The merger of black holes could release energy in the form of ELFs (bottom left of the image). It might be possible to detect their weak signals with quantum sensor networks such as the GPS network (top right in the image). Credit: Ill./©: Sarah and Hannah Lilienthal PRISMA+ scientists propose […]

This illustration generated by a computer model shows multiple black holes found within the heart of a dense globular star cluster. Credit: Aaron M. Geller, Northwestern University/CIERA New analysis of gravitational-wave data leads to wealth of discoveries. An international research collaboration including Northwestern Universityastronomers has produced the most detailed family portrait […]

Artist’s impression of two black holes about to collide. Credit: Mark Myers, ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) 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 secrets of the previously hidden […]
