Objectives List main objectives of the proposed research in order of priority [up to 4000 chars] Dark Energy is one of the biggest unsolved puzzles in the whole of science today. The primary objective of this grant is to obtain new constraints on the nature of this dark energy using CMB-large scale structure observations and the ages of massive elliptical galaxies at high redshift . Our specific objectives are: Calculating new predictions for the CMB-large scale structure correlations from the integrated Sachs-Wolfe (ISW) effect, and its dependence on the equation of state and speed of sound of the dark energy. In addition, we will determine the theoretical limits to these ISW constraints and make new predictions for future ISW experiments. Combine an array of present detections of the ISW effect to further constrain dark energy models. In addition, use new data from the Sloan Digital Sky Survey (SDSS) and SDSS-2dF LRG survey to obtain one of the best recent measurements of dark energy. Use new observations of a large number of massive elliptical galaxies at high redshift (SDSS and SDSS-2dF) to measure the evolution of the Hubble parameter and thereby obtain one of the first constraints of the equation of state of dark energy. Combining these constraints with more traditional probes of dark energy (SN, CMB) to distinguish between various theoretical dark energy and modified gravity models. K. Summary Describe the proposed research in a style that would be accessible to an interested 14 year old [up to 4000 chars] It has long been understood that the Universe we live in is expanding as the consequence of an initial `big bang” 13.8 billion years ago. Cosmologists had always assumed that this expansion was driven by ordinary matter (like you and me), which meant that the rate of expansion should be slowing down. However, in 1998, researchers found that by observing the brightness of very distant exploding stars, the expansion of the Universe actually appears to be accelerating not slowing down! This was a shock and has raised the question “What mysterious force driving this acceleration?” In 2003, it became clear that cosmologists needed some new kind of matter, much different than anything we have seen before, to dominate the Universe and beat the effect of gravity on the largest scales in the Universe. The existence of this new kind of matter, known as `dark energy’ because we have not been able to observe it directly, was hailed as the ``Breakthrough of the Year’’ by Science magazine in 2003. Given that this dark energy appears to be the most abundant component of our Universe, we are very interested to learn as much as we can about it. For example, how is it distributed in the Universe? Is there the same amount everywhere, or does it cluster into lumps like ordinary matter? Also, how does it evolve with time? Has it always dominated the Universe, or was there a time when it was less important? Finally, does it really exist, or is what we see just evidence that we do not understand how Einstein’s laws of gravity on very large distances? Unfortunately, dark energy is difficult to learn about. Precisely because it is `dark’, we cannot observe it directly and we have not found any evidence of it interacting with ordinary matter. Thus far we have only been able to see how it influences the expansion of the Universe gravitationally. All the evidence we have for it is fairly indirect, so we have learnt relatively little about it so far. The aim of this proposal is to try to look at dark energy differently from the ways its been observed before. One method will be to try to understand how the age of the Universe changed as it expanded, because this will show how fast the expansion occurred. To do this, we will use new data from new surveys of galaxies at high `redshift’, i.e. galaxies so far away from us that the light we see was emitted when the Universe was much younger. By looking at the light from these galaxies, we will try to determine how old the galaxies are. If we look at enough galaxies, the oldest ones we see should be nearly as old as the Universe itself was when the light was emitted. In this way, we will be able to follow how fast the expansion was, and whether the dark energy was important early in the history of the Universe. It’s analogus to looking for the oldest fossil on Earth to determine the age of our planet. Another way we plan on studying the dark energy is by looking at the heat , or light, left over from the initial big bang, known as the cosmic microwave background (CMB). This light has passed unperturbed since it was first emitted. It does interact gravitationally with large lumps of matter in the Universe, but usually the energy it gains falling into the gravitational field of the matter is lost when the light moves out of the influence of the matter. However, if dark energy is around, then suddenly this is no longer true. The light actually gains energy by having passed through the matter. Thus we can show the presence of dark energy if we see that the energy of the CMB light corresponds with the distribution of matter in the universe. This correspondence between the energy of the light and the matter in the Universe has actually been seen. This was first reported by investigators of this proposal, and gave important confirmation of the existence of dark energy. There is still much more to learn from this however, as it is not yet clear precisely when these correlations arose. We plan to investigate this, combining various existing surveys of the distribution of matter, and with data that is just coming in from the Sloan Digital Sky Survey. We also plan on looking for signs of clustering in the dark energy, since it should also interact gravitationally with the CMB. Finally, we will combine both of these new windows into the nature of dark energy with the more traditional approaches, in order to get a fuller picture of this mysterious substance that dominates our Universe.

Beneficiaries Describe who will benefit from the research [up to 4000 chars] The most immediate benefit will be to cosmologists aiming to understand how the Universe has evolved and why its expansion is accelerating. The results will also be of great interest to particle physicists struggling to understand the fundamental constituents of the Universe, in particular whether they will have to explain such a small value of a cosmological constant, or whether some kind of light scalar field dominates the Universe. In either case the implications for particle physics models could be dramatic and probe in physics beyond the standard model. Furthermore, our research will be of great interest to Relativitists and studies of Einsteins general theory of relativity, as it will potentially promote new theories of gravity on the largest scales in the Universe. In summary, the study of dark energy has profound consequences across the whole of physics and is one of the biggest puzzles in the whole of science. The computational algorithms we are developing as part of this research (eg fast cross-correlation codes run on large supercomputers) will be published via AstroGrid (AG) and the Virtual Observatory (VO), and therefore be of great benefit to other astronomers around the world. Bob Nichol is a senior member of the VO and AG. These algorithms will also be of benefit to other sciences like biology and geology , and we will work towards publishing them to as broad a community as possible Finally, as has been demonstrated by dark energy being named Science magazine’s ‘Breakthrough of the Year’ in 2003, the public clearly has a very strong interest in cosmology and in particular in this strange matter which dominates the Universe. For example, Bob Nichol (co-I of this proposal) was recently a guest on the US “David Letterman Show” to discuss his work with the SDSS and ISW effect, and its consequences for understanding dark energy. We will continue our public outreach efforts during this grant by exposing both students and the public to our work and any new results. .
