Probing dark energy using convergence power spectrum and bi-spectrum

Weak lensing convergence statistics is a powerful tool to probe dark energy. Dark energy plays an important role to the structure formation and the effects can be detected through the convergence power spectrum, bi-spectrum etc. One of the most promising and simplest dark energy model is the Lambda CDM. However, it is worth investigating different dark energy models with evolving equation of state of the dark energy. In this work, detectability of different dark energy models from Lambda CDM model has been explored through convergence power spectrum and bi-spectrum.
