Caustics in Dark Matter Haloes
Roya Mohayaee, Stephane Colombi, Bernard Fort +3
Caustics are formally singular structures, with infinite density, that form in collisionless media. The non-negligible velocity dispersion of dark matter particles renders their de…

Probing dark matter caustics with weak lensing
Raphael Gavazzi, Roya Mohayaee, Bernard Fort
Caustics are high-density structures that form frequently in collisionless media. Under self-gravity, cold dark matter flows focus onto caustics which are yet to be resolved in num…
