The intensity contrast of solar photospheric faculae and network elements II. Evolution over the rising phase of solar cycle 23
Ada Ortiz, Vicente Domingo, Blai Sanahuja
We studied the radiative properties of small magnetic elements (active region faculae and the network) during the rising phase of solar cycle 23 from 1996 to 2001, determining thei…
STELIB: a library of stellar spectra at R~2000
J. -F. Le Borgne, G. Bruzual, R. Pello +6
We present STELIB, a new spectroscopic stellar library, available at http://webast.ast.obs-mip.fr/stelib . STELIB consists of an homogeneous library of 249 stellar spectra in the v…
On the intensity contrast of solar photospheric faculae and network elements
A. Ortiz, S. K. Solanki, V. Domingo +2
Sunspots, faculae and the magnetic network contribute to solar irradiance variations. The contribution due to faculae and the network is of basic importance, but suffers from consi…
Spectroscopic Confirmation of Redshifts Predicted by Gravitational Lensing
Tim Ebbels, Richard Ellis, Jean-Paul Kneib +4
We present deep spectroscopic measurements of 18 distant field galaxies identified as gravitationally-lensed arcs in a Hubble Space Telescope image of the cluster Abell 2218. Redsh…
The population of galaxies in the distant clusters Cl 1613+3104 and Cl 1600+4109
Rosendo Vilchez-Gomez, Roser Pello, Blai Sanahuja
We study the photometric properties and content of the distant clusters of galaxies Cl 1613+3104 (z = 0.415) and Cl 1600+4109 (z = 0.540). The former is a rich, concentrated cluste…
