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

Simon Ding
Institut d'Astrophysique de Paris (Paris, France)

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.
