The study of the evolution of the Tully-Fisher relation has raised some problems during the last years. The main difficulty is determining the required parameters of intermediate redshift galaxies. In the present work, the rotational velocities obtained from the widths of different optical lines using DEEP2 spectra are compared. The apparent

We performed accurate and deep NIR (J,K) photometry of the Globular Cluster (GC) 47Tuc using data collected with SOFI at New Technology Telescope (NTT) (ESO, La Silla). Data cover a significant fraction of the innermost regions of the cluster and the Color Magnitude Diagram (CMD) ranges from the red HB down to the lower Main Sequence (MS). In the

For most black hole X-ray binaries, the fraction of X-ray flux originating in the synchrotron jets is generally thought to be low in the hard state. However in one intriguing case, using infrared -X-ray correlations, evolution of broadband spectra and timing signatures we show that synchrotron emission from a jet likely dominated both the infrared

We present results for a sample of absorbed Broad-line Active Galactic Nuclei (BLAGN) se-lected from a cross-correlation of the 2XMMi and Sloan Digital Sky Survey Data Release 6 catalogues. These sources are selected in X-ray to have 0.5-2 versus 2-4.5 keV X-ray hardness ratios which are harder than the X-ray background and in the same time to have
