The effect of baryons in the cosmological lensing PDFs
  Observational cosmology is passing through a unique moment of grandeur with
the amount of quality data growing fast. However, in order to better take
advantage of this moment, data analysis tools have to keep up the pace.
Understanding the effect of baryonic matter on the large-scale structure is one
of the challenges to be faced in cosmology. In this work, we have thoroughly
studied the effect of baryonic physics on different lensing statistics. Making
use of the Magneticum Pathfinder suite of simulations we show that the
influence of luminous matter on the 1-point lensing statistics of point sources
is significant, enhancing the probability of magnified objects with $\mu>3$ by
a factor of $2$ and the occurrence of multiple-images by a factor $5-500$
depending on the source redshift and size. We also discuss the dependence of
the lensing statistics on the angular resolution of sources. Our results and
methodology were carefully tested in order to guarantee that our uncertainties
are much smaller than the effects here presented.
