The New Map of Dark Matter sets out 10 million Galaxies available in Physics



Influences have an invisible effect on our universe. We can not see it, and we can not detect it – but we can look at how it interacts significantly to see and detect what we have such as light.

The international team of astronomers has now used one of the most powerful telescope in the world to analyze that effect across 10 million galaxies in the context of Einstein's general relatives. The product? The most comprehensive map of dark material throughout the history of the Universe to date.

Peer review has yet to be completed, but the map has suggested something unexpected – the global structures of the subjects may have evolved more slowly than previously here. 19659003] "If further details show that we are sure that it is right, it suggests that something is missing from our current understanding of the Standard Model and the general theory of relatives," said physicist Chiaki Hikage Kavli Institute for Physics and Mathematics of the Earth

We do not know what the dark thing is. We know that the effects of anxiety we see in the Earth can not be accounted for by sustainable content only. For example, the speed of rotation of the galaxies would be quite different if it was based on gravity only from a sensible mass.

We also know that gravity can double the path of light, as we can see with an economic lens. This effect can also be used to map dark material – when you take the unobtrusive effect of the material that is visible, you have left the impact of dark content concerns.

This is a common method of finding dark matter, which is also the Hikage team used. They imitate 8x-megapixel Hyper-Suprime-Cam the Subaru 8.2-meter telescope to reach regions billion years ago.

Because of their light to come to us, we look at them as they were billions of years ago, which means that the map covers much of the history of the universe, which allows astronomers look at how the dark material came over the billions of years.

The following 3D map shows the lumpy layout of the dark material of the Earth, in line with the results of the previous research – except for the speed of the structures coming to heads. According to this new map, it has been slower than anticipated by previous results.

Must, but enough to stand out as weird. He said that, the jury is still what he means. It could show that something is missing from the Standard Model, which would be wonderful; or may indicate statistical volatility in the data.

It may be for some time before it was discovered. The team is working on this project from 2014, using the first hundred year observations, or 11 percent of the Hyper Suprime Cam survey, which has not yet been completed. It is intended to take the picture in 2020 some time.

So we can not be over-motivated – there is still a complete maternity workload. But it's still its inspirational results, and we'll be waiting to get more information with the buffet breath.

"With a little bit more work, if we can get better accuracy, we might be able to get something on concrete," said Hikage. "This is a very exciting factor for me."

The team's research into the is published by the Japanese Astronomical Society and can be read fully on the preliminary server on Xiv.
