DESCRIPTION:I will show how it is possible to place stringent constraints 
 on high DM self-annihilation cross sections making use of cosmological obs
 ervables. Current CMB measurements do in fact allow the possibility to lim
 it down to the thermal values for particle masses of few GeV\, with constr
 aints that depend only on cosmological paramaters\, and are not affected b
 y astrophysical uncertainties. It is also possible to place strong constra
 ints on self--annihilation cross sections by using observations related to
  the Epoch of Reionization\, relying in this case on structure formation s
 cenarios.\n\nhttps://indico.ific.uv.es/event/1714/
