December 2020
Finally 2020 draws to a close and it has been a year unlike any other! We started the year with horrific bushfires significantly impacting our colleagues in NSW and the ACT before the world was hit by COVID-19. Despite the lockdowns, many determined OzGravvers have continued to be very scientifically productive and you can read about some of their achievements, prizes and dreams in this issue. Have a great holiday break over the Christmas period, you all deserve it! I know I am personally really looking forward to a break, and hope that with the rollout of vaccines we’ll soon return to our pre-COVID lives. |

November 2020
No matter where you are in the world there’s no doubt that 2020 has been a long year. For the three OzGrav nodes in Melbourne this has been especially so with two lockdowns in seven months, and little physical contact with our friends, colleagues and families. It is hard to describe the joy that easing of restrictions brings after hanging on the daily case numbers for what seems like an eternity. Collectively our staff have been remarkably productive during lockdown, and as you’ll see in this issue, pursuing some great science. But if my own emotions are anything to go by, it would be incredibly surprising if many of our staff and students haven’t found the year very challenging, and we’re constantly looking at how OzGrav can assist our members facing uncertain times in the academic sector. One of our favourite sections of Space Times is ‘Faces of OzGrav’. This month we meet the remarkably effervescent Dr Lilli Sun from the Australian National University (ANU), whose journey to an academic position was quite unique. We are also celebrating the wonderful news that the four elder statespersons of OzGrav, Professors David Blair, Susan Scott, David McClelland and Peter Veitch, were awarded the Prime Minister’s Prizes for Science!!! This is a fantastic achievement for these Australian pioneers of this field and the future of gravitational wave astronomy in Australia and OzGrav. |

September 2020 A special note to our Victorian-based members who have now been in one form of lockdown or restriction for the past 6 months. Most of us are well fed, have a roof over our head, and plenty of work to do. This doesn't make it an easy time though, and it is hard not to miss the freedoms that we have given up in order to suppress the virus. Let's hope that the case numbers keep falling and that Australia is soon on top of the second wave. This month, we cover fantastic research led and co-authored by our members, including the first ever monster intermediate black hole directly observed, and congratulate our OzGravver's on their recent achievements, such as winning the 3-minute thesis finals! |

August 2020 Despite these challenging times, especially for Victorians who are currently under Stage 4 lockdown, we are thrilled to see that, once again, OzGrav research has featured on the cover of the Australian Research Council’s annual magazine and that many of our determined researchers remain scientifically productive. |

July 2020 It's been a tough month, especially for those under lockdown again in Melbourne; however, the OzGrav community continues to make fantastic progress in their research efforts. This month the Centre was scheduled to have its mid-term review and it’s very reassuring to see so many of the OzGrav scientists and admin staff producing excellent work as featured in this newsletter. We're also delighted that gravitational waves are now a bona fide part of Australia’s astronomical research as featured in the Decadal plan’s mid-term review. |

June 2020 We are thrilled that our Governance Advisory Committee member Tamara Davis (now AM!!) made a member of the Queen’s Birthday Honours list, and PhD student Carolyn Maxwell won the Educator’s prize at the University of Western Australia. We hope you enjoy reading this edition of Space Times, full of new research highlights and stories from our OzGrav community. |

May 2020 The OzGrav community continues to achieve good scientific progress despite global adversities, including: the first public release of the COMPAS rapid binary population synthesis code (page 4); a new type of deformable mirror that could improve gravitational-wave detectors (page 8); and the monitoring of space probe BepiColumbo as it leaves Earth on its way to Mercury (page 3). |

April 2020 During these chaotic times of COVID-19, we're increasing efforts to stay connected and share our stories in different ways, including through Space Times. We''ll be publishing our newsletter every month from now on (instead of only every two months). In this edition, the spotlight shines on new research from our PhD students and postdocs including insights into the evolution of stars (page 6); common-envelope episodes (page 5); and future space detector LISA (page 4). We also congratulate Adam Deller on receiving the prestigious Pawsey Medal for scientific excellence (page 8) and take a look at what OzGravvers are getting up to in isolation (page 10)—from quilting to to cooking pierogi! |
|
February 2020 In this edition, we cover exciting results on quantum 'squeezing' by OzGrav researchers at Australian National University (page 3); new insights from our PhD students into the eccentricity of black holes (page 5) and gravitational-wave memory (page 11); and the recently published evidence for 'frame dragging'—a spinning celestial body twisting the fabric of space and time (page 6). We also learn more about our impressive members (page 8) and access schemes offered at OzGrav (page 7). |
|
December 2019 In this edition, we report on the upcoming collaboration between Japan’s Kamioka Gravitational-Wave Detector (KAGRA) with the USA’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and Europe’s Virgo (page 3); OzGrav researchers Juan Calderon Bustillo (Monash University) and Meg Millhouse (University of Melbourne) investigate the first collision of black holes with unequal masses (page 4); and OzGrav goes on an expedition to South Africa to commission the MeerKAT radio telescope (page 12). |
|
October 2019 In this edition, we explore the value of OzGrav’s gravitational wave science in improving self-driving cars and learn about the innovative methods of OzGrav’s Jeff Cooke and Garry Foran to hear the stars. We also cover stories about OzGrav Chief Investigator Ilya Mandel’s Tibetan trip teaching astrophysics to monks; the Zadko Observatory in Gingin, Western Australia; and the possible collision between a black hole and neutron star. |
August 2019
In this edition of Space Times, Associate Investigator Adam Deller and a team of scientists catch a glimpse into the past, present and future with the measurement of the Hubble Constant; Chief Investigator Jeff Cooke and the the Deeper Wider Faster program reveal more clues about Fast Radio Bursts; and University of Adelaide's 'mini LIGO' dubbed AMIGO demonstrates space-time warping, teaching students of all ages how the Universe works. As the global hunt for gravitational waves continues, OzGrav continues to grow and reach new heights: frequently appearing in the media, collecting prestigious awards and building a strong team.
