We have used the Mambo instrument on the IRAM 30m telescope to observe at 1.2mm 63 Spitzer-selected z>1 hyperluminous infrared galaxy candidates (HLIRGs) with...

Results of a ground-based CMB anisotropy experiment conducted at the Teide Observatory (Tenerife) are presented. The instrument is a four channel (3.1, 2.1, 1.3...

We examine the errors in the atmospheric parameters recovered from the inversion of spectro-polarimetric data with limited wavelength sampling. We suggest that...

Near-Earth objects (NEOs) deserve our attention because they pose an impact risk for Earth. A good example is the Chicxulub impactor that produced the...

(4) Vesta is the unique large asteroid with a basaltic surface present in the Asteroid Belt. In recent years, several smaller asteroids having similar...

TNOs (50000) Quaoar and 2002 TX300 were observed in the framework of a long-term program to study the surface properties of TNOs, Centaurs and comet nuclei...

Most of the V-types that are known are located in the inner main belt and are members of the Vesta collisional family. The analysis of the photometric and...

A-type asteroids are usually found in the main asteroid belt and their spectra are very similar to spectra of the silicate mineral olivine (Cruikshank and...

Visible and near-infrared spectra (0.5-2.4 μm) of TNOs (50000) Quaoar and 2002 TX300 taken with the Italian 3,56m "Telescopio Nazionale Galileo" are presented...
