Major improvements in the theoretical understanding of LSS have been possible due to the effective field theory approach. After an overview of the perturbation theory applications for LSS, I will discuss how to go beyond the one-loop calculation, presenting novel two-loop results and their information content (both for clustering and lensing). I will also show how to extract information from...

Peculiar velocities are a great probe of gravity allowing us to test the validity of general relativity on cosmic scales. I will describe the latest measurement of the growth rate of structures at redshift z = 0.07 using a combination of galaxy positions and direct peculiar velocities from the DESI Peculiar Velocity survey. Our measurements significantly contribute to constraining cosmological...
