Measuring the dark matter halo mass distribution with weak gravitational lensing using the Ultraviolet Near-Infrared Optical Northern Survey

In this project, the results from Ultraviolet Near-Infrared Optical Northern Survey will be used to model dark matter mass distribution around galaxies in the galactic cluster. Observing weak gravitational lensing of background galaxies from the optical multi-band survey and determining its parameters will help us to simulate dark matter halos around galaxies, that cause lensing, using physical models like Chabrier initial mass function and a truncated NFW model, and compare simulated parameters of the lensing phenomena to real measurements. This work is planned to improve existing models of distributions of dark matter mass around galaxies, which will be a crucial step in cosmological and evolutionary research of our universe. The results promise to discover more about the galactic structure and intergalactic interaction, as well as expand our knowledge of the nature of dark matter.
