We present the rotation curves of 967 spiral galaxies, obtained by deprojecting and folding the raw Hα data published by Mathewson et al.(1992). Of these, 80 meet objective excellence criteria and are suitable for individual detailed mass modelling, while 820 are suitable for statistical studies. A preliminary analysis of their properties confirms that rotation curves are a universal function o...

We discuss the use of crystal bolometers to search for weakly interacting cold dark matter particles in the galactic halo. For particles with spin dependent nuclear interactions, such as photinos, Majorana neutrinos and higgsinos, we show that compounds of boron, lithium, or fluorine are optimal detector components. We give careful estimates of expected cross-sections and event rates and discus...

Galaxies are lighthouses that sit atop peaks in the density field. There is good observational evidence that these lighthouses do not provide a uniform description of the distribution of dark matter.

Stars account for only about 0.5% of the content of the Universe; the bulk of the Universe is optically dark. The dark side of the Universe is comprised of: at least 0.1% light neutrinos; 3.5% ± 1% baryons; 29% ± 4% cold dark matter; and 66% ± 6% dark energy. Now that we have characterized the dark side of the Universe, the challenge is to understand it. The critical questions are: (1) What for...

What is the Bright Internet? One way to define ‘bright’ is to explore darkness. The purpose of this panel is to clarify what is meant by the ‘Bright Internet’ by presenting the contrast of the ‘Dark Internet’ and the dark web. The panelists, all of whom have expertise in the dark side of Internet and information technology use, will discuss deception, fraud, phishing, terrorism, and the dark web.

After a short review of the arguments for the existence of Particle Dark Matter in the Universe, I list the most plausible candidates provided by particle physics, i.e. neutrinos, axions, and WIMPs. In each case I briefly describe how to estimate the relic density, and discuss attempts at detecting these particles. At the end I discuss my personal favorite, the lightest supersymmetric particle,...

More than 90% of matter in the Universe could be composed of heavy particles, which were non-relativistic, or 'cold', when they froze-out from the primordial soup. I will review current searches for these hypothetical particles, both via interactions with nuclei in deep underground detectors, and via the observation of their annihilation products in the Sun, galactic halo and galactic center.
