Gravitational lensing probes ‘clumpiness’ of dark matter

An international team of astrophysicists and cosmologists, including Surhud More from Pune?s Inter-University Centre for Astronomy and Astrophysics, has used the Subaru telescope in Hawai?i to characterise the structure of dark matter in the universe using images. Dark matter is a hypothetical form of matter that is thought to account for approximately 85% of the matter in the universe.
