Alex has published two more articles for the Astrobites collaboration.

The first article is an interview with the organisers of the Cosmology from Home 2021 conference (which includes fellow Newcastle PGR Niko Sarcevic) about what makes a successful online conference. This includes a discussion about the aims of online conferences and how they may differ from in-person conferences, as well as some practical tips, tricks, and tools for building a conference online from the start.

The second article is a daily paper summary looking at recent work done by Dan Thomas Sankarshana Srinivasan, Francesco Pace, and Richard Battye in a series of two papers about how to build cosmological simulations for modified gravity in a model independent way. Paper I sets up a mathematical framework for extending standard techniques to work in both the large and small scale limit, even through an intermediate regime where both cosmic perturbation theory and Newtonian theory don’t apply. Paper II sets up modified gravity simulations using this framework and through some simple test cases demonstrates the importance of these sorts of techniques for exploring modifications to gravity in the era of next generation surveys.
