We do n’t know what dark issue is . We retrieve it exist because we see some peculiar gravitational effects on galaxies . the great unwashed are looking for drear topic particles in many experimentation , but uranologist are center on how it affects the larger social organization in the world .
A Yale - led team of astronomers has map the distribution of dark affair in three of the sixHubble Frontier Fields . These areas of the sky have a specific advantage that makes them optimal for this field of study . They are ( comparatively ) small regions with so much topic ( dour and visible ) that they turn away infinite - time itself , creating gravitative genus Lens .
These lenses bend the light from far away galaxy , and by written report how the light path is changed , it is possible to “ see ” dour thing . In a paper issue in theMonthly Notices of the Royal Astronomical Society , the team discuss the construction of the black affair maps for these cosmic regions .
" With the data of these three lensing clusters we have successfully map the granularity of non-white matter within the bunch in recherche detail , " Yale Astrophysicist Priyamvada Natarajan say in astatement . " We have mapped all of the clump of dark thing that the data let us to detect , and have grow the most detailed topologic mapping of the sorry matter landscape to date . "
The simulation they ran closely rival the distribution of the standard cosmogenic modelling , which expect dark matter to be “ cold ” , moving comparatively slowly around the universe of discourse . It also suggests something about these frontier field . The team suspects they are in reality in a transeunt evolutionary form and we might just be getting a snapshot of it all .
While the detail , like a band of things relate to dark topic , remain ill-defined , the expected amount and distribution of blue topic seems to match the theoretical prediction .
" While we now have a precise cosmic armory for the amount of colored matter and how it is distributed in the universe , the mote itself remains problematic , " Natarajan added .
Dark matter is believed to make up more than 80 pct of the whole subject subject matter of the cosmos , but the many lookup for its true nature are yet to bear fruit .
