In this summer internship the students will be introduced to the study of weak gravitational lensing and its applications in the field of cosmology and astrophysics. They will work within IFAE’s Observational Cosmology group, which is composed by several experts in the field. During the internship, students will use python software to simulate images of galaxies with known properties and then introduce weak lensing effects to study their impact. In that way, they will implement various dark matter density profiles, varying the mass distribution of the lens, and also the redshifts of the lens and source galaxies, understanding the relevant parameters that can affect the weak lensing distortions. They will also study the effect of galaxy blending, and use machine-learning techniques to distinguish these cases.
The internship will provide students with experience in python programming and data analysis, as well as the understanding of the weak lensing effect and its significance in cosmology and astrophysics. They will also gain experience in presenting and discussing their work and findings in front of colleagues at weekly group meetings.
