\abstract{
  Numerical simulations of structure formation have recorded a remarkable progress in the recent years, thanks to the inclusion of baryonic physics effects. 
I will present a recent analysis [1] of the sensitivity of Fermi-LAT to detect a subhalo population, built on the results of an hydrodynamical simulation of Milky Way-sized galaxies. The aim is to investigate the effect of baryonic physics on gamma-ray observables.

The detectability of dark matter subhalos is based on the 3FGL and 2FHL Fermi-LAT source catalogs. I will show how the flux sensitivity threshold strongly depends on the 
particle dark matter mass, and, more mildly, also on its annihilation channel and the observation latitude, and derive predictions for the number of dark matter subhalos that should be found among Fermi-LAT unassociated sources.

A null number of detectable subhalos in the Fermi-LAT 3FGL catalog would imply upper limits on the dark matter annihilation cross section compatible with the limits coming from dwarf spheroidal galaxies.
Finally, I will present results for extended subhalos.
