New Probes of Weak Lensing [abstract]

Weak gravitational lensing is one of the most promising observational tools in cosmology, as it measures the underlying total matter distribution rather than just the luminous baryonic matter. Commonly, weak lensing is measured using shear through galaxy ellipticities, or using the effect of magnification bias on galaxy number densities. I will report on the first detection of weak lensing magnification with a new, independent technique using the distribution of galaxy sizes and magnitudes. Our first application of this technique to an X-ray selected sample of galaxy groups in the COSMOS HST survey yields results consistent with shear measurements, and at roughly 40% of the signal-to-noise of the latter. I will discuss systematic issues and challenges to realizing the potential of this new probe of weak lensing.
