Simulating the Diffuse Neutrino Emission from the Milky Way with GALPROP

P. D. Marinos, T. A. Porter, G. P. Rowell +2

We use the GALPROP cosmic ray (CR) propagation framework to model the diffuse neutrino and gamma-ray emissions from the Galaxy. A collection of realistic bounding models are develo…

A comparison of optimisation algorithms for high-dimensional particle and astrophysics applications

The DarkMachines High Dimensional Sampling Group, Csaba Balázs, Melissa van Beekveld +18

Optimisation problems are ubiquitous in particle and astrophysics, and involve locating the optimum of a complicated function of many parameters that may be computationally expensi…

Luminosity Functions of Gamma-Ray Burst Afterglows

Guðlaugur Jóhannesson, Gunnlaugur Björnsson, Einar H. Gudmundsson

Aims: Use the standard fireball model to create virtual populations of gamma-ray burst afterglows and study their luminosity functions. Methods: We randomly vary the parameters of…
