In-depth analysis of the clustering of dark matter particles around primordial black holes. Part II. Analytical prescriptions for spikes
Julien Lavalle, Pierre Salati
Primordial black holes (PBHs) are very appealing dark matter (DM) candidates. It is highly plausible though, should they exist, that they would not make up all of the DM. Several s…

In-depth analysis of the clustering of dark matter particles around primordial black holes. Part III: CMB constraints
Julien Lavalle, Vivian Poulin, Pierre Salati
In a mixed dark matter scenario in which primordial black holes (PBHs) would co-exist with thermally produced self-annihilating particles, one expects the former to be surrounded b…
