SUMMARY:Buried in the noise.
DESCRIPTION:Buried in the noise.\nDr. Andrés Asensio Ramos\n\nAs astrophys
 icists, we are used to extracting physical information from  the observati
 ons. The usual procedure is to propose a parametric  physical model to exp
 lain the observations and use the observations  to infer the values of the
  parameters. However, in our noisy and  ambiguous universe, the solution t
 o the inference problem is usually  non-unique or diffuse. For this reason
 , it is important that our  inversion techniques give reliable results. In
  this talk I present a few  recent results (dusty tori of AGN, magnetic fi
 elds in central stars of  planetary nebulae, oscillations of coronal loops
 , signal detection) in  which our group is applying Bayesian ideas to extr
 act information from  the observations.
