Dynamics of blue compact galaxies, as revealed by their H-alpha velocity fields I. The data, velocity fields and rotation curves
G. Östlin, P. Amram, J. Masegosa +2
Observations of six luminous blue compact galaxies (BCGs) and two star forming companion galaxies were carried out with the CIGALE scanning Fabry-Perot interferometer attached to t…
The Broad Line Radio Galaxy J2114+820
L. Lara, I. Marquez, W. D. Cotton +4
In the frame of the study of a new sample of large angular size radio galaxies selected from the NRAO VLA Sky Survey, we have made radio observations of J2114+820, a low power radi…
The optical/IR counterpart of the 3 July 1998 gamma-ray burst and its evolution
A. J. Castro-Tirado, M. R. Zapatero-Osorio, J. Gorosabel +21
We imaged the X-ray error box of GRB 980703, beginning 22.5 hours after the gamma--ray event, in both the optical R and near-infrared H bands. A fading optical/IR object was detect…
Quantum evolution according to real clocks
Inigo L. Egusquiza, Luis J. Garay, Jose M. Raya
We characterize good clocks, which are naturally subject to fluctuations, in statistical terms. We also obtain the master equation that governs the evolution of quantum systems acc…
The Radio-Optical Jet in NGC 3862 from Parsec tu Sub-Kiloparsec Scales
L. Lara, L. Feretti, G. Giovannini +4
We have observed the radio source NGC 3862 (3C264) simultaneously with the EVN and the MERLIN arrays, obtaining detailed images of its radio structure from parsec to sub-kiloparsec…
Multiwavelength study of the starburst galaxy NGC7714. I: Ultraviolet-Optical spectroscopy
Rosa M. Gonzalez Delgado, Maria Luisa Garcia-Vargas, Jeff Goldader +2
We have studied the physical conditions in the central 300 pc of the proto-typical starburst galaxy NGC 7714. Our analysis is based on ultraviolet spectroscopy with the HST+GHRS an…
