Clumpiness of the dark matter mapped

From denial of its existence to acceptance of its importance in the universe is a complete turnaround of sorts. Though this hasn’t happened overnight, but the journey looks very long indeed.

Scientists have come out with detailed map of dark matter that they reportedly discovered in cosmos. Reports suggest that the latest and the most detailed map of dark matter was actually created by Dark Energy Survey. Astronomers are pretty sure that the new map may help scientists in revealing its important role in galaxy formation.

Dark matter has been one of the biggest mysteries in the universe. Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world’s most powerful digital cameras, are the largest contiguous maps created at this level of detail and will improve our understanding of dark matter’s role in the formation of galaxies.

The new maps were created using data captured by the Dark Energy Camera, a 570-megapixel imaging device that was the primary instrument for the Dark Energy Survey (DES).

It is needless to say that it is going to be of immense use in the days to come. This analysis was led by Vinu Vikram of Argonne National Laboratory (then at the University of Pennsylvania) and Chihway Chang of ETH Zurich. Vikram, Chang and their collaborators at Penn, ETH Zurich, the University of Portsmouth, the University of Manchester and other DES institutions worked for more than a year to carefully validate the lensing maps.
