| « How to make pretty radio galaxy images with Bayesian inference » |

Since the first discovery of extraterrestrial radio signals in 1932 by
Karl Guthe Jansky, radio astronomy has established itself as an important subfield and contributed to a better understanding of astrophysical and cosmological processes. As with most observations in physics the raw data will need to be post-processed and thus the scientific value that one can get out of these observations rely on the post-pocessing pipeline. With technical advances in modern telescopes like VLBI, MeerKAT, ${YourFavoritRadioTelescope}, the demand increases for better algorithms and methods to effectively extract information from recent radio astronomical observations. In the upcoming YMCA talk I will give an introduction to Bayesian inference and radio interferometry and finally show how it can be combined to produce pretty images of radio galaxies. In particular, I will show you the results that I obtained from a VLA observation of Hydra A. |
