SAS Lecture: Making a universe from scratch

About this event :

Astronomy is mostly a visual and non-experimental science.
We can only look at what is out there but can’t brings stars and galaxies into the lab.

However we can build them inside computers and attempt to simulate them.
In Julian’s talk, we will see how simulations can show us how the universe evolves and what we can do with them, and what areas we are still struggling to make models of.

Talk via Zoom at Wetlands Centre

This walk will be held via Zoom but shown at the Washington Wetlands Centre (Discovery Room).

Please show you support to our speaker and the Society if you can on the night.

Hopefully we’ll see you all at the Washington Wetlands Centre (Discovery Room) , a Raffle & Refreshments as usual.


Zoom Access

The talk will be over Zoom and  it’s recommended to attend in person at the Washington Wetlands Centre to get the best to get the best experience from the talk & Q&A..

Our speaker

Dr Julian Onions. Post Doctoral Researcher

Julian works with computer simulations of large fractions of the universe to understand trends in galaxy formation and evolution.

Investigating the tools that help us form and analyse such simulations such as halo finders, tree builders and semi-analytic models.

He also does a number of outreach activities, giving talks to astronomy societies and other interested groups such as rotary and U3A, as well as working with schools and scouts/guide groups. He also helps with the teaching of undergraduates in some of the astronomy courses.
