Spitzer IR Array Camera (IRAC) mid-infrared photometry is presented for the globular cluster (GC) systems of the NGC 5128 (`Centaurus A') and NGC 4594 (`Sombrero') galaxies. Existing optical photometric and spectroscopic are combined with this new data in a comprehensive optical-to-mid-IR colour catalogue of 260 GCs. Empirical colour-metallicity

We report high-resolution spectroscopy of the moderately reddened (AV=3) early-type star Cernis 52 located in a region of the Perseus molecular cloud complex with anomalous microwave emission. In addition to the presence of the most common diffuse interstellar bands (DIBs) we detect two new interstellar or circumstellar bands coincident to within 0

We present initial results of a comparative near-infrared (NIR) spectroscopic study of the Themis and Veritas asteroid families. These two families are compositionally primitive (mainly Tholen C-types) and likely formed in the same region of the protoplanetary disk. However, their disruption ages are at opposite extremes: 2.5 Gy and 8.3 My

The European Solar Telescope (EST) is a project for a 4 meter-class ground-based telescope, to be located in the Canary Islands. The project is promoted by the European Association for Solar Telescopes (EAST), a consortium formed by research organizations from 15 European countries. EST will be optimized for studies of magnetic coupling between the

In Table 1 of our original paper we include the coordinates of the centers of the 3.7' long slits obtained in the observations. However, these do not correspond to the centers of the slits drawn in our Figure 1, which represents the extension of the portions of the slits that we finally analyze in the paper (we remove some sections, as indicated in

We study how the regolith properties affect the measured fluorescent soft X-ray spectra from atmosphereless planetary surfaces as a function of mean particle size and particle size distribution, surface roughness and viewing geometry. The relative fluorescent elemental line intensities from the X-ray spectra measured from a planetary surface can be
