"The cosmic dispersion measure in the EAGLE simulations" - Batten et al. (2021)
Alan Duffy
A wonderful new paper by my student Adam Batten. Mysterious explosions occur across the sky from distant galaxies, visible only with radio telescopes, known as Fast Radio Bursts (FRBs). There illuminate the intervening material as they travel to our telescopes, allowing us to probe that otherwise hard to image Cosmic Web. But how do we know what that should look like? Simulations like EAGLE predict that distribution and in this beautiful work by Adam we can therefore shine simulated FRBs through this to create predictions for the dispersion measure. This then is directly tested by the telescopes.
