While astrophysical and cosmological probes provide a remarkably precise and consistent picture of the quantity and general properties of dark matter, its fundamental nature remains one of the most significant open questions in physics. Obtaining a more comprehensive understanding of dark matter within the next decade will require overcoming a number of theoretical challenges: the groundwork for these strides is being laid now, yet much remains to be done. Chief among the upcoming challenges is…

Astrophysical and cosmological probes of dark matter

Dark matter has been introduced to explain substantial mass deficits noted at different astronomical scales, in galaxies, groups of galaxies, clusters, superclusters and even across the full horizon.

Probing the nature of dark matter particles with stellar streams

A key prediction of the standard cosmological model—which relies on the assumption that dark matter is cold, i.e. non-relativistic at the epoch of structure formation—is the existence of a large

Lectures on Dark Matter Physics

Rotation curve measurements provided the first strong indication that a significant fraction of matter in the Universe is non-baryonic. Since then, a tremendous amount of progress has been made on

Earth-mass dark-matter haloes as the first structures in the early Universe

TLDR
Supercomputer simulations of the concordance cosmological model, which assumes neutralino dark matter (at present the preferred candidate), are reported, and it is found that the first objects to form are numerous Earth-mass dark-matter haloes about as large as the Solar System.

Cosmological Probes of Dark Matter Interactions: The Next Decade

Cosmological observations offer unique and robust avenues for probing the fundamental nature of dark matter particles-they broadly test a range of compelling theoretical scenarios, often surpassing

A small amount of mini-charged dark matter could cool the baryons in the early Universe

TLDR
If a small fraction of the dark matter has a mini-charge, a million times smaller than the charge on the electron, and a mass in the range of 1–100 times the electron mass, then the data from the EDGES experiment can be explained while remaining consistent with all other observations.

21-cm Fluctuations from Charged Dark Matter.

TLDR
Here, for the first time, the 21-cm fluctuations caused by a charged subcomponent of the dark matter are computed, including both the pre- and postrecombination evolution of all fluids, thus providing a novel probe of dark matter at cosmic dawn.

Gravitational probes of dark matter physics

Dark matter-neutrino interactions through the lens of their cosmological implications

Dark matter and neutrinos provide the two most compelling pieces of evidence for new physics beyond the Standard Model of particle physics, but they are often treated as two different sectors. The

Black holes, gravitational waves and fundamental physics: a roadmap

The grand challenges of contemporary fundamental physics—dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem—all involve gravity
