We carry out a statistical analysis of galaxy pairs selected from chemical hydrodynamical simulations with the aim at assessing the capability of hierarchical scenarios to reproduce recent observational results for galaxies in pairs. Particularly, we analyse the effects of mergers and interactions on the star formation (SF) activity, the global

We explore the use of Integral Field Spectroscopy (IFS) for observing extrasolar planet transits. We show that IFS can improve the photometric accuracy in high S/N time series observations with respect to standard slit spectrophotometry. Ground based observations of HD209458b obtained with WHT + INTEGRAL during a transit have led to an accuracy in

We have in recent years come to view the outer parts of galaxies as having vital clues about their formation and evolution. Here, we would like to briefly present our results from a complete sample of nearby, late-type, spiral galaxies, using data from the SDSSsurvey, especially focused on the stellar light distribution in the outer disk. Our

Based on optical data we propose a dynamycal model for A115. From spatial and radial velocity distributions we find three massive subsclusters that configure a pre-merging scenario. On this basis, we discuss on the origin of the radio emission and its correlation with X-rays.

The Near Infrared Spectrograph (NIRSpec) on board of the James Webb Space Telescope (JWST) will be equipped with an Integral Field Unit (IFU) which will allow the two-dimensional spectral characterization of astronomical objects with unprecedented depths, especially in the 2-5 micron wavelength range. In particular, NIRSpec-IFU observations of high
