On 2002 we started an observational campaign devoted to the study of the surface composition of Jupiter Trojans. In particular we focused on the study of members of dynamical families: we obtained visible spectra of 80 objects belonging to 10 different families and for 24 of them we obtained also near-infrared spectra. All the investigated bodies

The narrow-band optical images in several of the most important atomic lines and neighbouring continuum were secured at Las Campanas Observatory (LCO) in 1994 March 17-22, using the 40-in. telescope (LCO-40) and the TEK1 1024x1024 pixel detector. The narrow-band filters are centred in the following emission lines: H{beta}, [OIII] 5007{AA}, Hα, [NII

Aims.In order to show the importance of high spatial resolution observations of extra-galactic sources when compared to observations obtained with larger apertures such as ISO, we present N-band spectra (8-13 μm) of some locations in three starburst galaxies. In particular, we show the two galactic nuclei of the spiral galaxy NGC 3256, the compact

Since the discovery of the first short-population γ-ray burst (GRB) afterglows in 2005, the handful of observed events have been found to be embedded in nearby (z 1), bright underlying galaxies. We present multiwavelength observations of GRB 060121, the first short burst observed to clearly outshine its host galaxy (by a factor >102). A

The optical/near-infrared (OIR) region of the spectra of low-mass X-ray binaries (XBs) appears to lie at the intersection of a variety of different emission processes. In this paper we present quasi-simultaneous OIR-X-ray observations of 33 XBs in an attempt to estimate the contributions of various emission processes in these sources, as a function

The 3D magnetic field topology of solar filaments/prominences is strongly debated, because it is not directly measureable in the corona. Among various prominence models, several are consistent with many observations, but their related topologies are very different. We conduct observations to address this paradigm. We measure the photospheric vector
