Friday 29th March 2019

This Friday guest speaker Floor Broekgaarden will give a talk entitled "Unpuzzling the origin of gravitational waves"

The direct detection of gravitational waves originating from merging binary black holes and neutron stars has opened up a new window into the Universe and has marked the birth of gravitational-wave astrophysics. The first gravitational-wave observing runs have been completed, yielding eleven merger events, and we can anticipate hundreds of detections per year when the next generation of detectors come online. This growing set of data will help Astrophysicists solve one of the biggest unanswered questions in the field: “what is the origin of these gravitational-wave mergers?”. In this (interactive) talk we will go through the current ideas of where these gravitational waves come from. We will also discuss some of the state-of-the-art machine-learning algorithms that are used by astronomers to solve this problem - which turn out to be similar to some well-known puzzle strategies.


Floor Broekgaarden graduated in 2018 with Masters in Astrophysics & Astronomy from the University of Amsterdam after completing a Bachelor degree in both Mathematics and Physics. She is currently working as an Astrophysicist at Monash University in Melbourne and will start her PhD this September at the Center for Astrophysics at Harvard! Floor's research focuses on gravitational waves, Finding out where they originate from. To solve this question she studies and uses different techniques of Machine Learning, Big Data and Statistics.

Friday 30th November 2018 - Stephanie Rowlands

8pm Friday 30th November 2018 we have our very own Stephanie Rowlands giving a talk on her research project work at the Anglo Australian Telescope.

 The formation and evolution of galaxies is a major focus of ongoing study in  astrophysics. The region of gas surrounding many galaxies, called the Circum-galactic medium (CGM), has been linked to this process. Finding out more on the properties and distribution of this gas is vital to gain a clearer insight into the processes within galaxies.

The objective of my research was to identify regions of this CGM gas around 4 winter-sky galaxies and our own Milky Way using distant quasars and detailed spectroscopy measurements which I will share during my presentation.

Members' Night is on every Friday night. Guests of members are always welcome. Contributions of food to share for supper are always gratefully received!

Friday 16th November 2018 - Jacquie Milner - Beginners Night: Common Telescope Design

8pm Friday 16th November 2018 we have the latest in Jacquie Milner's beginners series of talks, looking at why telescopes are made in different ways this time.

With the season of gift giving nearing you may be thinking about buying a telescope, but overwhelmed by the choice on hand. Why do they make so many? Where do you start? Tonight we will take a look at the common designs on the market, their positives and negatives, and find out why do telescopes get made that way?

Members' Night is on every Friday night. Guests of members are always welcome. Contributions of food to share for supper are always gratefully received and demolished! :-)


Please consider the neighbours and drive in and out quietly using low beam only, or better still, parking lights.
