Cosmic Microwave Background observations
In the first part of this talk I will present a historical review of the CMB observations, one of the most powerful cosmological probes. Following the first...

CharlaCosmology on small scales: the structure of (mostly) dark matter halosThe standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...
