I've been away for the last few weeks, but in that time some exciting progress has been made by a number of my students and collaborators. Congratulations first of all to PhD student Teagan Clarke who submitted her first research paper, and also gave her first conference presentation at the Astronomical Society of Australia's annual meeting. Teagan even won the third best student talk award! Isobel Romero-Shaw also submitted another paper in which we show approximately four of the binary black hole mergers detected to date in gravitational waves have non-zero eccentricity, giving further weight to the hypothesis that most of these binary systems for dynamically in dense stellar environments. Finally, we submitted a paper that was a collaboration between OzGrav scientists (Jade Powell and Lilli Sun at Swinburne and ANU, respectively}, and the Eliiza data science company, using machine learning to characterise noise artifacts in gravitational-wave detector data, and create artificial artificats that can be used to test search and parameter-estimation pipelines, as well as understand instrumental systematics.

A fun outreach event tonight. I went along to a virtual space night for the Brighton Sea Scouts group, where I spoke with the cubs (7.5 - 11 years old) about what astrophysicists do, and answered all their questions about how the Universe works.

The LIGO/Virgo collaborations have just announced the detection of the most massive black holes yet. The system is known as GW190521; my group has done a lot of work on this event, including most notably Isobel Romero-Shaw and former postdoc Juan Caderon Bustillo, who worked mainly on the event while at Monash. Isobel was also interviewed by the ABC in a great article that gives good insight into why we find this even so exciting.

Proud to announce that I'm a co-author of the first Australia-New Zealand edition of the first-year physics textbook Halliday's Fundamentals of Physics published by Wiley.

More press today for our proposed NEMO gravitational-wave detector, including some quotes from me. Check it out.

I gave a talk today to the Orange Pulsar meeting on the science case and instrument design for our proposed high-frequency detector NEMO.

I attended and presented at a fantastic meeting (albeit at 3am local time) this morning to discuss the future of ground-based gravitational-wave astronomy instrumentation. It was a meeting involving the European Einstein Telescope Consortium, the US Cosmic Explorer Consortium, and our NEMO team from OzGrav. I was fortunate enough to present the key science case for our proposed NEMO.

I was interviewed by the national Community and Indigenous Radio Station The Wire about our proposed new high-frequency gravitational-wave detector NEMO. Listen to the interview here.

I've been a big part of the OzGrav team that has now published the science case and design for a gravitational-wave detector that we're calling NEMO: the Neutron Star Extreme Matter Observatory. The article was made public on the arXiv today. We also did some great pres around the article, including a really nice article in The Age newspaper, as well as a press release from Monash University. NEMO has also been listed as a recommended project in the Australian Academy of Sciences Decadal Plan mid term review that was also released today.

I gave a webinar today representing OzGrav as part of the Australian Institute of Physics webinar series. My talk presented the details of a high-frequency gravitational-wave detector, OzHF, that we would like to build in Australia to discover merging neutron stars throughout the Universe and learn fundamental nuclear physics. If you missed the webinar, you can watch the recording on YouTube here. The paper and a press release will appear next week.

Extremely proud of my PhD student Isobel Romero-Shaw, who today submitted her first paper. In the paper, we perform astrophysical inference on the first catalogue of binary black hole mergers detected with Advanced LIGO and Virgo, looking for signs of orbital eccentricity that would give hints as to their formation history. We set upper limits on the eccentricity of all events that indicates they likely formed through binary stellar evolution. There are exciting times ahead, with theoretical predictions suggesting we may be able to detect non-negligible eccentricities from dynamically formed mergers very soon!

Congratulations to my PhD student Isobel Romero-Shaw who was awarded the best student talk at the Astronomical Society of Australia Annual Meeting this week!

I'm at the Astronomical Society of Australia Annual Meeting this week, where I presented a talk covering some of the many projects we're doing with our new Bilby software. Many of my PhD students also presented: Isobel Romero-Shaw gave a plenary talk on measuring eccentricity in the binary black holes LIGO has detected, Moritz Huebner talked about detecting gravitational-wave memory, and Paul Easter presented a poster on gravitational waves from post-merger remnants.

Our new paper hit the arXiv today. It's been accepted into the journal Nature Astronomy, to appear in the journal in mid-August. We looked at the 2016 Vela glitch and concluded the following: 1) The rise time of the glitch is less than 12 seconds-the previous record was 30 seconds. 2) There's a frequency overshoot and approximately 60 second decay back to the equilibrium value; this is the first indirect evidence for three components in the core. 3) There appears to be an anti-glitch, or frequency slow down, immediately before the glitch. We have no idea what that is, but speculate that it could be the cause of the glitch.

I'm extremely proud of Hayley Macpherson who today submitted her PhD 'Inhomogeneous cosmology in an anisotropic Universe'. Hayley has done an exceptional job with this thesis, so much so that she's off to Cambridge for a prize fellowship postdoc starting in October. It's been a fantastic experience having Hayley as a student, and I wish her all the best in her future endeavours.
