Studying Blazars with Multiwavelength and Multi-messenger Astronomy - Professor Markus Böttcher

Blazars are some of the brightest and most vibrant objects known to astronomers: emitting high-velocity jets of matter, and producing gamma rays which outshine almost all other sources in the known universe. To study these phenomena, astronomers must use the latest techniques to observe blazars simultaneously at different wavelengths of electromagnetic radiation, while also capturing the elusive neutrinos they emit. In a recent article, Dr Markus Böttcher, an astronomer at North-West University on Potchefstroom, South Africa, presents an overview of the latest advances in these ‘multiwavelength’ and ‘multi-messenger’ techniques – and where they could lead in the near future.
