Catalogue of Spatially Resolved Kinematics of galaxies . ... The goal of the present project is to built a catalogue gathering references to all spatially resolved studies, for galaxies of all types, whatever the gas or stellar content is concerned. The catalogue has been assembled from merging the lists of Corradi and Capaccioli (1990) and Prugniel and Simien (1996). ... In total, the published catalogue contains 4165 observations of 2070 galaxies referring to 743 published papers. ...

Our understanding of star formation in galaxies is facilitated by observations, at multiple wavelengths, of emission which traces stellar populations. ... Using optical integral field spectroscopy, my work aims to better understand the local SFR calibrations, which use H-alpha and radio continuum emission, when applied to different regions of a galaxy, as well as to galaxies as a whole. ...

... QSO spectra in the ROSAT band are steeper than the background at harder energies, and furthermore at fluxes below 1E-14 ergs/(s cmќ) the quasar source counts flatten off and are replaced by more numerous populations of relatively low red-shift objects, apparently Narrow Emission Line Galaxies (NELG). ... We extracted the luminosity function from ROSAT Deep Survey results, and extrapolated by a factor of 2 - 3 to account for changes expected in the harder XMM band. ...
