How we can learn more about the astrophysics of the most extreme neutron stars and how hierarchical models can be applied to gain both potentially fascinating and statistically robust insights into the compact object population detected via gravitational wave emission.

The Research School of Astronomy and Astrophysics (RSAA) will be hosting a 1-day symposium on 18 September highlighting the contributions of scientists at Mount Stromlo since the establishment of the Commonwealth Solar Observatory 100 years ago.

What is the dark energy that’s accelerating the Universe? Discovered a quarter of a century ago, it’s a feature of our Universe that appears to have some sort of anti-gravity property. Now astronomers have zeroed in on how it’s changed over the last 10 billion years. Using thousands of supernovae and millions of galaxies they’ve mapped the cosmos and discovered to their surprise that dark energy may be changing with time. This talk will describe the many varied ways in which astronomers are measuring the dark side of the Universe, and get you up to date on the recent exciting results.

As part of the Mount Stromlo Observatory 100th anniversary celebrations, we will be holding an open day in November.
