Description
Weak gravitational lensing causes small displacements in the apparent angular position of quasars, and of the Lyman-alpha forests in their spectra. By measuring local distortions from the Lyman-alpha auto and quasar cross correlation functions, we propose to reconstruct the lensing mass distribution. With tests on eBOSS and DESI mocks, we expect to make S/N forecasts for these and future surveys.
