First 3-D map of the universe's dark matter scaffolding
01-07-2007 · EurekAlert!By analysing the COSMOS survey -- the largest ever survey undertaken with Hubble -- an international team of scientists has assembled one of the most important results in cosmology: A three-dimensional map that offers a first look at the web-like large-scale distribution of dark matter in the universe. This historic achievement accurately confirms standard theories of structure formation.

- The first 3-D map of the universe
03-03-2007 · EurekAlert!
An International team of scientists from CNRS (France), CEA, (France) and Caltec (USA) made the first 3-D map of dark matter in the universe using gravitational lensing effects. The team analyzed the Cosmos field, the largest field of galaxies ever observed with the Hubble space telescope. This study can be found in the Jan. 7, 2007, issue of Nature.

- Have researchers found a new state of matter?
03-14-2007 · EurekAlert!
A 25-year old experiment is turning everything we know about matter upside down, and may even have demonstrated an example of an entirely new state of matter. The US researchers have dubbed this new state, "string-net liquid," and even speculate that the entire universe could be made of it. Others may even have found a candidate for such a material: a dark green crystal called herbertsmithite found in the mountains of Chile in 1972.

- Dilaton could affect abundance of dark matter particles
10-01-2007 · EurekAlert!
The amount of dark matter left over from the early universe may be less than previously believed. Research published in the open-access journal PMC Physics A shows that the 'relic abundance' of stable dark matter particles such as the neutralino may be reduced as compared to standard cosmology theories due to the effects of the 'dilaton,' a particle with zero spin in the gravitational sector of strings.

- The violent lives of galaxies: Caught in the cosmic matter web
01-10-2008 · EurekAlert!
Astronomers are using the NASA/ESA Hubble Space Telescope to dissect one of the largest structures in the Universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of galaxies.

- FSU physicist shining a light on mysterious 'dark matter'
10-02-2007 · EurekAlert!
We've all been taught that our bodies, the Earth and in fact all matter in the universe is composed of tiny building blocks called atoms. Now imagine if this weren't the case. This mind-bending concept is at the core of the scientific research that one Florida State University professor -- and hundreds of his colleagues all over the world -- are pursuing.

01-10-2008 · EurekAlert!
For the first time astronomers are able to see indirect evidence of dark matter and how this invisible force impacts on the crowded and violent lives of galaxies. University of British Columbia researcher Catherine Heymans has produced the highest resolution map of dark matter ever captured before.
