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

At a redshift of 0.18, Abell 1689 is so far the most distant cluster of galaxies for which substantial mid-infrared (MIR) data have been published. Its mapping with the ISOCAM camera onboard the ISO satellite allowed the detection of 30 cluster members at 6.75 micron (LW2 filter) and 16 cluster members at 15 micron (LW3 filter) within a

We simulate the characteristics of the Galactic population of radio and γ-ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially distributed in the Galactic disk, with supernova-kick velocities, and randomly dispersed in age back to 109 yr. They are evolved in the Galactic gravitational potential to the present time. From a

As the epoch of spheroid formation in massive galaxies is believed to correspond to the growth of active nuclei, probing the population of obscured AGN at high redshift is a particularly important capability of deep Chandra and XMM surveys. We present first results of the ELAIS/SCUBA Chandra survey, including optical and IR spectroscopic
