Abstract
Time has come to probe for the presence of weakly-interacting massive parti cles in the Milky Way. These species may contribute a substantial fraction to the mass of our galaxy. They may dominate its gravity and dynamical bala nce on large scales. Their mutual annihilations would yield several indirec t signatures that are potentially detectable on Earth as extra-components t o the various cosmic radiations. I will review those indirect signatures an d show that the situation has significantly evolved since the last 1997 TAU P Conference. In particular, neutralinos may have followed the collapse of the massive black hole that sits at the galactic center. If so, the resulti ng dark matter spike would be such a strong gamma-ray and neutrino source t hat the entire supersymmetric parameter space could be within reach of the near future instruments.
