TL;DR: In this paper, the authors considered the possibility that the black-hole binary detected by LIGO may be a signature of dark matter and showed that there remains a window for masses 20M⊙ √ √ m −1 −2 m −3 m −2 n −1 where primordial black holes (PBHs) may constitute the dark matter.

TL;DR: The CMB-S4 project as mentioned in this paper is a ground-based cosmic microwave background (CMB) experiment with superconducting cameras, which will be used for the search for the B-mode polarization signature of primordial gravitational waves and the determination of the number and masses of neutrinos.

TL;DR: 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.

TL;DR: In this paper, the authors explore whether dark-matter particles with an electric "minicharge" can significantly alter the baryonic temperature and, thus, affect 21-cm observations, and find that the entire dark matter cannot be minicharged at a significant level, lest it interferes with Galactic and extragalactic magnetic fields.
