The injection of secondary particles produced by dark annihilation around redshift 1000 would inevitably affect the process of recombination, leaving an imprint on cosmic microwave background (CMB) temperature and polarization anisotropies. We show that the most recent CMB measurements provided by the WMAP satellite mission and the ACT telescope place interesting constraints on DM...

I will focus on constraints that can be imposed on the properties of dark matter based on observations of neutron stars and white dwarfs. In particular, I will show constraints on WIMP self-interactions (that in some cases are stricter than the bullet cluster) as well as constraints on generic asymmetric dark matter derived from observations of nearby old neutron stars.
