We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

Primordial black holes are under intense scrutiny since the detection of gravitational waves
from mergers of Solar-mass black holes in 2015. More recently, the development of …

Recent measurements of the cosmic microwave background (CMB) anisotropies by Planck
provide a sensitive probe of dark matter annihilation during the cosmic dark ages, and …

We update the constraints on the fraction of the Universe going into primordial black holes in
the mass range 10 9–10 17 g associated with the effects of their evaporations on big bang …

We compute cosmic microwave background (CMB) anisotropy constraints on exotic forms of
energy injection in electromagnetic (em) channels over a large range of timescales. We …

We review sterile neutrinos as possible Dark Matter candidates. After a short summary on
the role of neutrinos in cosmology and particle physics, we give a comprehensive overview …

The energy spectrum of the cosmic microwave background (CMB) allows us to constrain
episodes of energy release in the early Universe. In this paper, we revisit and refine …

We compute in detail the rate at which energy injected by dark matter (DM) annihilation
heats and ionizes the photon-baryon plasma at z∼ 1000, and provide accurate fitting …

We calculate the post-recombination contribution to the cosmic microwave background
(CMB) spectral distortion due to general exotic energy injections, including dark matter (DM) …
