Gravitational lensing potential reconstruction in quadruply imaged systems
We develop a semi-analytical method to reconstruct the lensing potential in quadruply imaged gravitational lens systems. Assuming that the potential belongs to a broad class of boxy non elliptical models, we show how it is possible to write down a system of equations which can be numerically solved to recover the potential parameters directly from image positions and using physical constraints....
متن کاملA new method for the estimate of H0 from quadruply imaged gravitational lens systems
We present a new method to estimate the Hubble constant H0 from the measured time delays in quadruply imaged gravitational lens systems. We show how it is possible to get an estimate of H0 without the need to completely reconstruct the lensing potential thus avoiding any a priori hypothesis on the expression of the galaxy lens model. Our method only needs to assume that the lens potential may b...
متن کاملCluster mass reconstruction from weak gravitational lensing
Kaiser & Squires have proposed a technique for mapping the dark matter in galaxy clusters using the coherent weak distortion of background galaxy images caused by gravitational lensing. We investigate the effectiveness of this technique under controlled conditions by creating simulated CCD frames containing galaxies lensed by a model cluster, measuring the resulting galaxy shapes, and comparing...
متن کاملFlux and color variations of the quadruply imaged quasar
Aims. We present VRi photometric observations of the quadruply imaged quasar HE0435-1223, carried out with the Danish 1.54 m telescope at the La Silla Observatory. Our aim was to monitor and study the magnitudes and colors of each lensed component as a function of time. Methods. We monitored the object during two seasons (2008 and 2009) in the VRi spectral bands, and reduced the data with two i...
متن کاملGravitational lensing
This is a short and biased review of gravitational lensing with emphasis on the radio and especially VLBI aspects. We briefly explain the basic idea and give a short sketch of the discovery of the first lens before we more systematically discuss the general fields that can be studied with lensing. We intentionally omit the details the average lensing expert would like to see and instead try to ...
