We present a cross-correlation of the European Large Area Infrared Space Observatory (ISO) survey (ELAIS) with the ELAIS Deep X-ray Survey of the N1 and N2 fields. There are seven Chandra point sources with matches in the ELAIS Final Analysis 15-μm catalogue, out of a total of 28 extragalactic ISO sources present in the Chandra fields. Five of

We present synthetic spectral energy distributions (SEDs) for single-age, single-metallicity stellar populations (SSPs) covering the full optical spectral range at moderately high resolution [full width at half-maximum (FWHM)=2.3Å]. These SEDs constitute our base models, as they combine scaled-solar isochrones with an empirical stellar spectral

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 using the Italian 3.58 m Telescopio Nazionale Galileo (TNG) at "El Roque de los Muchachos" Observatory (La Palma, Spain). Near-infrared spectra of both TNOs and visible spectrum of 2002 TX300
