Query: Neutrino Mass and Dark Energy from Weak Lensing   Weak gravitational lensing of background galaxies by intervening matter
directly probes the mass distribution in the universe. This distribution, and
its evolution at late times, is sensitive to both the dark energy, a negative
pressure energy density component, and neutrino mass. We examine the potential
of lensing experiments to measure features of both simultaneously. Focusing on
the radial information contained in a future deep 4000 square degree survey, we
find that the expected (1-sigma) error on a neutrino mass is 0.1 eV, if the
dark energy parameters are allowed to vary. The constraints on dark energy
parameters are similarly restrictive, with errors on w of 0.09. Much of the
restrictive power on the dark energy comes not from the evolution of the
gravitational potential but rather from how distances vary as a function of
redshift in different cosmologies.
