Searches for dark matter subhaloes with wide-field Cherenkov telescope surveys

Understand

The presence of substructures in dark matter haloes is an unavoidable consequence of the cold dark matter paradigm.

• Indirect signals from these objects have been extensively searched for with cosmic rays and gamma-rays.
• At first sight, Cherenkov telescopes seem not very well suited for such searches, due to their small fields of view and the random nature of the possible dark matter substructure positions in the sky.
• However, with long enough exposure and an adequate observation strategy, the very good sensitivity of this experimental technique allows us to constrain particle dark matter models.
