Scientific paper

We propose a new cluster deprojection algorithm for recovering cluster structure along the line of sight (los) based on the Richardson-Lucy (RL) algorithm, which recovers a nonnegative theoretical distribution from a given projection. To optimize our reconstruction we combine X-ray and Sunyaev-Zeldovich (SZ) data with gravitational lensing maps. The combination of these three data types constrains the structure of rich clusters of galaxies. To validate our new approach, we apply the algorithm to gas-dynamical cluster simulations. A reconstruction using the lensing potential is shown.
