In the recent development, it has been said that an international group of researchers which have released the most in-depth wide-field map of the 3D distribution of this matter that is present in the universe.
The results that they have got is obtained by studying the images of 10 million distant galaxies which are captured by the hyper Suprime-Cam Survey (HSC) of Japan located in Hawaii. The team consists of Surhud More, who is an Associate Professor at the Inter-University Center for Astronomy and Astrophysics (IUCAA), Pune.
This type of dark matter interacts gravitationally along with the ordinary matter forming lumps like galaxies, stars as well as superclusters. Dark energy accounts for the observed for the accelerated expansion of this universe. There is no direct way to detect or even the study which is both dark matters as well as dark energy except by examining this imprint they can leave in the large-scale structure which is during the evolution of this universe.
The researchers have said that they have reconstructed a highly precise 3D distribution of the dark matter. This was done by analyzing the minute distortions that are caused by the gravitational lensing.
In this study, the data collected have shown about how the fluctuations of the dark matter are present across the sky and how they have changed over the billions of years about how the dark energy which has influenced in this growth of the structure.
HSC is said to be an 820 MP camera which was attached to the 8.2 meter Subaru telescope which is at the summit of Mauna Kea, Hawaii. In the year 2014, the researchers who are from Japan, Taiwan as well as US which is led by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Project. In this survey, Assistant Professor Chiaki Hikage as well as a collaborative group which is chaired by Surhud More.
According to Kavli IPMU Principal Investigator, Masahiro Takada said that this is like the first step as well as they complete data of HSC survey which promises to take advance to the understanding of the dark matter as well as dark energy. HSC is said to be still taking the images as well as current results which are based on only 11 per cent of the full survey which is said to be expected to be completed by the year 2020.
