A wealth of astronomical data indicate the presence of mass discrepancies in the Universe.
The motions observed in a variety of classes of extragalactic systems exceed what can be …

Current upper bounds on the neutron electric dipole moment constrain the physically
observable quantum chromodynamic (QCD) vacuum angle| θ¯|≲ 10− 11. Since QCD …

We use cosmological simulations to study the effects of self-interacting dark matter (SIDM)
on the density profiles and substructure counts of dark-matter haloes from the scales of …

We review progress in understanding dark matter by astrophysics, and particularly via the
effect of gravitational lensing. Evidences from many different directions now all imply that five …

Dark matter is one of the greatest unsolved mysteries in cosmology at the present time.
About 80% of the Universe′ s gravitating matter is nonluminous, and its nature and …

We provide a systematic measurement of the rest-frame UV continuum slope β over a wide
range in redshift (z∼ 2–6) and rest-frame UV luminosity (0.1 L* z= 3 to 2 L* z= 3) to improve …

Weak gravitational lensing is a unique probe of the dark side of the universe: It provides a
direct way to map the distribution of dark matter around galaxies and clusters of galaxies as …

The annihilation of dark matter into neutrinos over a range of dark matter masses from MeV/c
2 to ZeV/c 2 is reviewed. Thermally produced models of dark matter are expected to self …

Ultralight axionlike particles can contribute to the dark matter near the Sun, leading to a
distinct, stochastic signature in terrestrial experiments. We search for such particles through …

We present a detailed strong-lensing, weak-lensing and X-ray analysis of Abell 2744 (z=
0.308), one of the most actively merging galaxy clusters known. It appears to have …
