Want to simulate some other universes with me? Looking for life in a (simulated) cosmos? Desperate to test some multiverse theories? You too could make classy videos like this!

Using supercomputer simulations of galaxy formation, we will investigate the effect of fundamental cosmological parameters on structure in the universe. We will model the formation of galaxies in lumpier and smoother sub-universes, and universes with different amounts of dark matter. Our group has previously explored the effect of the cosmological constant (arxiv.org/abs/1801.08781), and will extend and expand this approach, working with a world-leading galaxy formation code.

What does the scholarship provide?

  • Domestic students will receive a tax-free stipend of $30,000 per annum for up to 3 years to support living costs. Tuition fees will be supported by the Research Training Program (RTP) Fees Offset.
  • International students will receive a tax-free stipend of $30,000 per annum to support living costs. Those with a strong track record will be eligible for a tuition fee waiver.
  • All international students are required to hold an Overseas Student Health Care (OSHC) policy covering the duration of study, with the scholarship including funding for Single cover.
  • Support for conference attendance, travel and additional costs as approved by the School.

For eligibility conditions, and to apply, see the details here.

Applications close on October 14.

I’ve got a few talks upcoming in Sydney. Come and see the show!

2 August 2018, Sutherland Astronomical Society

Title: Following Light to the Beginning of the Universe
Time: 7:30pm – 9:30pm
Location: Green Point Observatory, Oyster Bay
Free. (I think. Maybe a gold coin for tea and coffee). More details here.

Abstract: How do we know what the Universe is made of? And what shapes its parts into the stars, galaxies and clusters of galaxies that we see around us? Starting from the very early universe, I’ll discuss how the fundamental factors of our universe, its forces, particles, and the dynamical stage that they tread (space time), compete and cooperate to fashion the Universe today.

5 August 2018, St Mark’s Darling Point

Title: The Big Questions – Science and God
Time: 8am, 10am and 5:30pm
Location: 1 Greenoaks Ave, Darling Point NSW 2027
More details here.

Come and enjoy the beautiful Garden under a starry sky! You will learn about Western and Aboriginal views of the night sky.

Dr Luke Barnes, astronomer at Western Sydney University will introduce you to the night sky over Mount Annan and the Macarthur Astronomical Society will bring out their telescopes so you can experience the best views. Our Aboriginal educators from Shared Knowledge will share their dreamtime stories about Australian sky and talk about how the visibility of certain star signs influences their lives.

If the weather permits you will have the opportunity to watch the stars and planets close up through the telescopes. A glass of wine will round up an amazing night experience.

Time: 4.45 pm-6.15 pm
Location: Narellan Road, Mount Annan 2567
Cost: $29.00 per person / Garden member $25.00. No walk-ins. Tickets must be purchased in advance here.

13 August 2018, St. Luke’s Clovelly

Time: 7.45 for snacks, 8pm start
Location: Corner Arden St and Varna St, Clovelly (location)
More details here.

17 August 2018, Centennial Park

Event: Astronomy in the Park

Immerse yourself into a night of stargazing. Looking up we see the bright and the dark – explained by our scientists of the Sydney Observatory, and by our aboriginal educator who will share his stories about the sky with us. At our telescope station, you will have the chance to observe the sky and ask our scientists about the phenomena you discover.

Once you and your group have discovered the sky and the park, we will wind up the evening at a campfire where you can relax, reflect the stories you heard, and enjoy a night in the park under the stars.

Time: 5pm-7pm
Location: Wild Play Discovery Centre, Dickens Drive, Centennial Park
Cost: $29.00 adults / Children $15.00. Find more details and purchase tickets here.

My most recent paper with Pascal Elahi (UWA), Jaime Salcido (Durham), Richard Bower (Durham) and Geraint Lewis (Sydney), as part of the Eagle Collaboration, is doing the rounds of the popular press. I’ll post some of the articles here, and keep updating. Check out the video!

I’ll be speaking at University Of Technology, Sydney on Monday 16th April, 2018. This event was originally pitched to me as another talk about the book, but has since evolved into a four-person discussion/debate event with Prof Peter Slezak (UNSW), Ian Bryce, and Mike Paget.

You may be familiar with Prof Slezak from his very interesting debates with Dr William Lane Craig, which I’ll put below. So I’m hopeful for an entertaining evening.

Time: April 16, Monday 6.30-8.30pm
Location: Aerial Function Centre @ Building 10, Level 7

This is a ticketed event – $10. I have no idea why. Book your tickets at Eventbrite.

I’m in the final stages of moving to a new position at Western Sydney University, so prepare for some more blogging soon about new and important things!

In the meantime, I’ll be speaking in Sydney tomorrow (Monday 19th March, 2018) at the Macarthur Astronomical Society.

Title: The Universe and Entropy, or The top 10 things to do before the heat death of the universe.
Time: Monday 19th March, 2018 at 7:30pm
Location: The small lecture theatre in Building 30 (School of Medicine) at Western Sydney University, Campbelltown Campus.
Public entry is by a gold coin donation

For the last 13.7 billion years, a variety of complex structures have assembled in the universe we see around us: nebulae, stars, planets, galaxies and more. But the infamous “second law of thermodynamics” says that the universe is winding down, moving from order to chaos.

How do these ideas fit together? Is the story of the universe order from chaos, or chaos from order?
