Descripción
Lens galaxies are objects of great interest in extragalactic astronomy
and cosmology and were one of the first targets in the history of IFS.
We will present new data obtained with INTEGRAL of some gravitational
lens systems. Thanks to the very good spectral performance of
INTEGRAL-WYFFOS --covering all the optical range at once-- we can
discuss the extinction in the very distant lens galaxies from the
visible to the UV and compare with the extinction curves in our local
environment (the Milky way and the Magellanic Clouds). This study also
provide an independent method for determining the redshift in a lens
galaxy (dust redshift). We will also present some maps of extended line
emission useful to study the host galaxy of the lensed QSO.
