DESCRIPTION:I present here a scenario\, based on a low reheating temperatu
 re $ T_R \\ll 100$~MeV at the end of (the last episode of) inflation\, in 
 which the coupling of sterile neutrinos to active neutrinos can be as larg
 e as experimental bounds permit (thus making this neutrino ``visible'' in 
 future experiments). In previous models this coupling was forced to be ver
 y small to prevent a cosmological overabundance of sterile neutrinos. Here
  the abundance depends on how low the reheating temperature is. For exampl
 e\, the sterile neutrino required by the LSND result might not have any co
 smological problem within our scenario.\n\nhttps://indico.ific.uv.es/event
