[en] Until recently little more was known than that dark matter appears to exist; there was little systematic information about its properties. Only in the past several years was progress made to the point where dark matter density distributions can be measured. For example, with accurate rotation curves extending over large ranges in radius, decomposing the effects of visible and dark matter to measure dark matter density profiles can be tried. Some regularities in dark matter behaviour have already turned up. This volume includes review and invited papers, poster papers, and the two general discussions. (Auth.)

[en] In this paper, an idea on dark matter nonconcentric with luminous matter is proposed. This case could influence the rotation curve of galaxy differently in its different direction. Recently, Rubin and Ford's observation on rotation curve of Hickson 88a has been explained by means of the idea. Some possible observational predictions have also been given. (author)

[en] This paper discusses dark matter in general, neutrino dark matter in particular, and the status of possible observations. The authors find the situation very promising

[en] The CRESST-III experiment which is dedicated to low-mass dark matter search uses scintillating CaWO₄ crystals operated as cryogenic particle detectors. Background discrimination is achieved by exploiting the scintillating light signal of CaWO₄ and by a novel active detector holder presented in this paper. In a test setup above ground, a nuclear-recoil energy threshold of $E_{\mathit{th}}=(190.6\pm 5.2)\mathrm{eV}$ is reached with a 24 g prototype detector, which corresponds to an estimated threshold of ∼50 eV when being operated in the low-noise CRESST cryostat. This is the lowest threshold reported for direct dark matter searches. For CRESST-III phase 1, ten such detector modules were installed in the cryostat which have the potential to improve significantly the sensitivity to scatterings of dark matter particles with masses down to ∼0.1 GeV/c².

[en] Facing with observational evidence of large voids in the galaxy distribution, a new statistical indicator is developed which allows a quantification of voids properties at each scale of work. A systematic analysis of the Center for Astrophysics redshift survey allows to compare the statistical properties versus the size and location of the sub-sample tested, the luminosity class and morphological type involved, and a confrontation with theoretical models. A scaling invariance will be evidenced in the distribution

[en] We show that in the late-infall model of our galactic halo of Sikivie the expected phase of the annual modulation of a weakly interacting massive particle (WIMP) halo signal in direct detection experiments is opposite to the one usually expected. If a nonvirialized halo component due to the infall of (collisionless) dark matter particles cannot be rejected, an annual modulation in a dark matter signal should be looked for by experimenters without fixing the phase a priori. Moreover, WIMP streams coming to Earth from directions above and below the galactic plane should be expected, with a characteristic pattern of arrival directions

[en] Though the concept of a dark energy driven accelerating universe was introduced by the author in 1997, to date dark energy itself, as described below has remained a paradigm. We quickly review these and find a second cosmological signature of the 1997 model, consistent with latest observations. (author)
