The authors analyze a set of optically faint emission-line galaxies discovered as strong Hα emitters in an objective prism survey (Wamsteker et al, 1985). This...
Selection of a Sample of Suitable Potential Mid-Infrared Calibration Stars from the Hipparcos/Tycho Catalogue
With the increasing availability of sensitive mid-IR area detectors on large telescopes there is a pressing need to increase the number and faintness of mid...
Selection of the GTC dome and support areas configuration
Several options for the GTC (Gran Telescopio Canarias) installations have been evaluated. In particular, different dome types and distribution schemes for the...
Self-absorption effects in the equivalent width of the spectral lines in a neon microwave plasma at atmospheric pressure
The ratio of the intensities is related to the emph{equivalent width}, W, of the spectral lines, which shape is approximated to a Voigt function resulting from...
Self-consistent models for Coulomb heated X-ray pulsar atmospheres
Calculations of accreting magnetized neutron star atmospheres heated by the gradual deceleration of protons via Coulomb collisions are presented. Self...
Self-sustaining galactic winds in spiral galaxies with starburst nuclei
In the circumnuclear zones of the disks of some spirals there is an absence of neutral interstellar hydrogen. A model is devised in which gaseous outflow is...
SPARQL is the W3C candidate recommendation query language for RDF. In this paper we address systematically the formal study of SPARQL, concentrating in its...
Results are reported from a search for fluctuations in the cosmic microwave background radiation (CMBR) on angular scales of 2 deg or greater at 10.4 GHz. Data...
Sensitivity of oscillation frequencies to temporal variations in the tachocline region
We have analyzed the differences in the oscillation eigenfrequencies measured over four years of GONG, SOI/MDI and LOWL observations (1996 to 1999). We have...
