Extractions: We review some recent determinations of the amount of dark matter on galactic, cluster, and large scales, noting some puzzles and their possible resolutions. We discuss the interpretation of big bang nucleosynthesis for dark matter, and then review the motivation for and basic physics of several dark matter candidates, including Machos, Wimps, axions, and neutrinos. Finally, we discuss how the uncertainty in the models of the Milky Way dark halo will affect the dark matter detection experiments. References and citations for this submission:

These cold, weakly interacting particles (WIMPs) are expected to be scattered by the nuclei of typical detector material at a rate of less than one per kg per day, yielding energy depositions in the 1-10 keV energy range. ICSTM plays a leading role in the UK Dark Matter Consortium (RAL, Imperial College, University of Sheffield) which has placed scintillation detectors in a well shielded, underground environment to search for signatures of WIMPs. Our first detector was a 6 kg NaI detector placed in a large tank of purified water, 1100m deep in the

Extractions: home research people contact ... Selected References m day This work is well funded at ICSTM with a 4-year rolling grant in place, with a team of about 8 people involved. PhD opportunities exist in both data analysis and detector development. The possible projects are very much instrument biased although there is some freedom to explore also relevant astrophysical aspects. To learn more look at the UK Dark Matter Search site The Antarctic Muon Neutrino Detector Array (AMANDA), located at the South Pole is currently the largest operating detector of neutrinos in the world. The detector is scheduled for expansion (IceCube) towards instrumentation of 1km of Antarctic ice. AMANDA has been collecting data since 1990. There are opportunities for AMANDA data analysis as well as preparatory work for IceCube. Of particular interest is the investigation of cataclysmic events that would produce neutrino emission as well as Gravitational Waves (see later section). Possible sources of such emissions could be the coalescence of blackhole-companion systems or collapsing supermassive stars. Both of these have been postulated as possible candidates to explain Gamma Ray Bursts (GRB).
Extractions: They could estimate what the rotation speed should be by calculating the mass of all the visible stars and gas, thereby determining the gravity of the galaxy. Much to their surprise, the measurements showed that most galaxies are rotating faster than they should. Not a little faster. Much faster! More than twice as fast. This meant that, according to Einstein's theory of gravity, these galaxies should be flying apart. Yet clearly, they are not.

Extractions: Astronomers have used NASA's Chandra X-ray Observatory to make the most detailed probe yet of the distribution of dark matter in a massive cluster of galaxies. Their results indicate that about 80 percent of the matter in the universe consists of cold dark matter - mysterious subatomic particles left over from the dense early universe. Chandra observed a cluster of galaxies called Abell 2029 located about a billion light years from Earth. The cluster is composed of thousands of galaxies enveloped in a gigantic cloud of hot gas, and an amount of dark matter equivalent to more than a hundred trillion Suns. At the center of this cluster is an enormous, elliptically shaped galaxy that is thought to have been formed from the mergers of many smaller galaxies. The X-ray data show that the density of dark matter increases smoothly all the way into the central galaxy of the cluster. This discovery agrees with the predictions of cold dark matter models, and is contrary to other dark matter models that predict a leveling off of the amount of dark matter in the center of the cluster. "I was really surprised at how well we could measure the dark matter so deep into the core of a rich cluster," said Aaron Lewis of the University of California, Irvine, lead author of a paper describing the results in a recent issue of The Astrophysical Journal. "We still have very little idea as to the exact nature of these particles, but our results show that they must behave like cold dark matter."

Extractions: A quantity obtained by multiplying the mass of an orbiting body by its velocity and the radius of its orbit. According to the conservation laws of physics, the angular momentum of any orbiting body must remain constant at all points in the orbit, i.e., it cannot be created or destroyed. If the orbit is elliptical the radius will vary. Since the mass is constant, the velocity changes. Thus planets in elliptical orbits travel faster at perihelion and more slowly at aphelion . A spinning body also possesses spin angular momentum.
