The Dark-Matter Fraction in the Elliptical Galaxy Lensing the Quasar PG1115+080
D. Pooley, S. Rappaport, J. Blackburne +3
We determine the most likely dark-matter fraction in the elliptical galaxy quadruply lensing the quasar PG1115+080 based on analyses of the X-ray fluxes of the individual images in…

External Shear in Quadruply Imaged Lens Systems
Gilbert P. Holder, Paul L. Schechter
We use publicly available N-body simulations and semi-analytic models of galaxy formation to estimate the levels of external shear due to structure near the lens in gravitational l…
