Weak Gravitational Lensing and its Applications

Wentao Luo

Based on the high quality imaging survey data, we can achieve unprecedented measurement of weak lensing signal and further study the connection between dark matter halo and galaxies residing inside them. What is more, people also realize that weak lensing can achieve way more than only galaxy formation in LCDM frame work. For instance, there are constraints on Emergent Gravity, and cosmologies where dark matter and dark energy interact with each other e.t.c. Here in this talk, I would like to present non-standard cosmology constraints other than LCDM from weak gravitational lensing.
