The Lens Redshift and Group Environment for He 0435 - 1223
The redshift of the galaxy lensing HE 0435−1223 is 0.4546 ± 0.0002, based on observations obtained with the Low Dispersion Survey Spectrograph 2 (LDSS2) on the Magellan Consortium’s 6.5 m Clay telescope. Hubble Space Telescope/ACS observations of the system also reveal a spiral-rich group of 10 galaxies within 40 of the elliptical lensing galaxy. The redshifts for two of these galaxies were mea...
متن کاملHalo Structures of Gravitational Lens Galaxies
We explore the halo structure of four gravitational lenses with well-observed, thin Einstein rings. We find that the gravitational potentials are well described by ellipsoidal density distributions in the sense that the best-fit nonellipsoidal models have parameters consistent with their ellipsoidal counterparts. We find upper limits on the standard parameters for the deviation from an ellipse ...
متن کاملIntegral-field spectrophotometry of the quadruple QSO HE 0435−1223: Evidence for microlensing
We present the first spatially resolved spectroscopic observations of the recently discovered quadruple QSO and gravitational lens HE 0435−1223. Using the Potsdam Multi-Aperture Spectrophotometer (PMAS), we show that all four QSO components have very similar but not identical spectra. In particular, the spectral slopes of components A, B, and D are indistinguishable, implying that extinction du...

After a brief introduction to gravitational lensing theory, a rough overview of the types of gravitational lensing statistics that have been performed so far will be given. I shall then concentrate on recent results of galaxy-galaxy lensing, which indicate that galactic halos extend much further than can be probed via rotation of stars and gas.

For the quadruple gravitational lens PG 1115+080, we combine recent measurements of the time delays with new lens models to determine the Hubble constant H 0. We explore the effects of systematic uncertainties in the lens models on the estimates of H 0 , and we discuss how the uncertainties can be reduced by future observations. We find that the lens cannot be fit by an isolated lens galaxy, bu...
