Optically bright Active Galactic Nuclei in the ROSAT-Faint Source Catalogue
M. -P. Veron-Cetty, S. K. Balayan, A. M. Mickaelian +8
To build a large, optically bright, X-ray selected AGN sample we have correlated the ROSAT-FSC catalogue of X-ray sources with the USNO catalogue limited to objects brighter than O…
On the jet speeds of classical double radio sources
T. G. Arshakian, M. S. Longair
A simple integral relation is obtained for the distribution functions of jet speeds and jet-counterjet flux asymmetries of classical double radio sources. Analytic expressions rela…
The First Deep ACS Lyman alpha Images of Local Starburst Galaxies
D. Kunth, C. Leitherer, J. M. Mas-Hesse +2
We report the first results from a deep Lya imaging program of local starburst galaxies with the Advanced Camera for Surveys (ACS) of the Hubble Space Telescope. The two observed g…
Eclipses by circumstellar material in the T Tauri star AA Tau. II. Evidence for non-stationary magnetospheric accretion
J. Bouvier, K. N. Grankin, S. H. P. Alencar +12
We report the results of a synoptic study of the photometric and spectroscopic variability of the classical T Tauri star AA Tau on timescales ranging from a few hours to several we…
Serendipitous discovery of seven new southern L-dwarfs
T. R. Kendall, N. Mauron, M. Azzopardi +1
We report the discovery of seven hitherto unknown L-dwarfs found as a result of a spectroscopic search for distant AGB stars. Their far-red and near-infrared colours are very simil…
