Title: ABS, CMB foreground removal, weak lensing reconstruction by counting galaxies, and beyond

Abstract: We present an Analytical method of Blind Separation (ABS) as a solution to CMB foreground removal, weak lensing reconstruction through cosmic magnification, the thermal Sunyaev Zel'dovich effect measurement, and beyond. We formulate the above questions into the same mathematical structure, for which we have discovered the analytical solution of the desired cosmological signal, free of assumptions of undesired foregrounds/contaminations. The ABS method may have applications in other astrophysical questions. The major purpose of this talk is to introduce the ABS method and to seek the possibility of new applications.
