Lens modelling and H0 estimate in quadruply lensed systems
We present a numerical method to estimate the lensing parameters and the Hubble constant H0 from quadruply imaged gravitational lens systems. The lens galaxy is modeled using both separable deflection potentials and constant mass to light ratio profiles, while possible external perturbations have been taken into account introducing an external shear. The model parameters are recovered inverting...
متن کاملJ 1131 - 1231 : New Light on Lens Substructures
We have observed the quadruply lensed quasar 1RXS J1131-1231 with the integral field spectrograph mode of the Kyoto Tridimensional Spectrograph II mounted on the Subaru telescope. Its field of view has covered simultaneously the three brighter lensed images A, B, and C, which are known to exhibit anomalous flux ratios in their continuum emission. We have found that the [OIII] line flux ratios a...
متن کاملSlit and integral-field optical spectroscopy of the enigmatic quasar
Context. Interest in the quasar HE0450-2958 arose following the publication of the non-detection of its expected massive host, leading to various interpretations. Aims. This article investigates the gaseous and stellar contents of the system through additional VLT/FORS slit spectra and integral field spectroscopy from VLT/VIMOS. Methods. We apply our MCS deconvolution algorithm on slit spectra ...
متن کاملObservations of the Quadruply Lensed Quasar RX J 0911 . 4 + 0551
We present results from X-ray observations of the quadruply lensed quasar RX J0911.4+0551 using data obtained with the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra X-ray Observatory. The 29 ks observation detects a total of ∼ 404 X-ray photons (0.3 to 7.0 keV) from the four images of the lensed quasar. Deconvolution of the aspect corrected data resolves all four lensed images, ...

We present results from X-ray observations of the quadruply lensed quasar RX J0911.4]0551 using data obtained with the Advanced CCD Imaging Spectrometer on board the Chandra X-Ray Observatory. The 29 ks observation detects a total of D404 X-ray photons (0.3 to 7.0 keV) from the four images of the lensed quasar. Deconvolution of the aspect-corrected data resolves all four lensed images, with rel...
