One of the great scienti®c enigmas still unsolved, the existence of dark matter, is reviewed. Simple gravitationa l arguments imply that most of the mass in the Universe, at least 90%, is some (unknown) non-luminous matter. Some particle candidates for dark matter are discussed with particular emphasis on the neutralino, a particle predicted by the supersymmetric extension of the Standard Model...

I discuss the prospects of detecting the smallest dark matter bound structures present in the Milky Way by searching for the proper motion of γ-ray sources in the upcoming GLAST all sky map. I show that for dark matter particle candidates that couple to photons the detection of at least one γ-ray microhalo source with proper motion places a constraint on the couplings and mass of the dark matte...

I both review and make the case for the current theoretical prejudice: a flat Universe whose dominant constituent is nonbaryonic dark matter, emphasizing that this is still a prejudice and not yet fact. The theoretical motivation for nonbaryonic dark matter is discussed in the context of current elementary-particle theory, stressing that (i) there are no dark-matter candidates within the "stand...

This is a brief review of aspects galactic astrophysics and astronomy which have possible bearing on particle dark matter. It still quite normal for physicists to try solve “well known anomalies“ that are apparently seen in observations galaxies (missing satellites, cusp vs. core, etc.) whereas lot these anomalies actually been resolved many years ago. We will briefly the field discuss areas qu...

The term “particle–hole symmetry” is beset with conflicting meanings in contemporary physics. Conceived and written from a condensed-matter standpoint, the present paper aims to clarify sharpen terminology. In that vein, we propose define operation of conjugation” as tautological algebra automorphism simply swaps single-fermion creation annihilation operators, construct its invariant lift Fock ...
