The image is a cover slide for a lecture to Liverpool Astronomical Society on 21st February 2025 by Dr. Steve Barrett of the University of Liverpool entitled "Cosmic Rays". The background is a picture of the Earth in space, with cosmic rays entering its atmosphere. The cosmic rays appear as thin streaks of light in the very upper atmosphere which expand into narrow, feathery cones of fainter particles as they get closer to the surface of the planet. Overlaid in the bottom right is a multicoloured 4x5 grid which reads left-to-right, from top-to-bottom: STAR WARS HAIL RAIN RAYS to the left of the word RAYS, outside of the grid and above the backdrop of the Earth is the word COSMIC.

An image of a mysterious, black void surrounded by a white ring, perhaps an event horizon? Innumerable streamers are coming from the surface of the ring, like electricity. There is no scale given, so we could br seeing anthing from a proton to a super-massive black hole. The image is energetic! It says "The End of Everything" : "The fate of the Earth, the Sun, …and the Universe"

Talk: Galactic Archaeology (The 2015 John Porter Memorial Lecture)

The history of computer simulations of galaxies like our own Milky Way is dotted with remarkable successes, but an even greater number of impressive failures. This inability to make a model of the Milky Way is quite surprising, given that the basic physics is well understood, and part of the A-level syllabus here in the United Kingdom. Recent advances suggest that we might have finally made a breakthrough, making use of powerful supercomputers and novel approaches to feeding energy into the forming galaxies. Brad will demonstrate how we “mine the fossil record” of our simulated galaxies, comparing and contrasting the […] Continue Reading »
