Determining the extragalactic extinction law with SALT
Ido Finkelman, Noah Brosch, Alexei Y. Kniazev +7
We present CCD imaging observations of early-type galaxies with dark lanes obtained with the Southern African Large Telescope (SALT) during its performance-verification phase. We d…
Adaptive optics imaging and optical spectroscopy of a multiple merger in a luminous infrared galaxy
P. Vaisanen, S. Mattila, A. Kniazev +16
(abridged) We present near-infrared (NIR) adaptive optics imaging obtained with VLT/NACO and optical spectroscopy from the Southern African Large Telescope (SALT) of a luminous inf…
The soft X-ray excess AGN RE J2248-511
R. L. C. Starling, E. M. Puchnarewicz, E. Romero-Colmenero
We model the spectral energy distribution of the ultrasoft broad-line AGN RE J2248-511 with Comptonised accretion disc models. These are able to reproduce the steep optical and ult…
On the Period-Luminosity-Colour-Metallicity relation and the pulsational characteristics of lambda Bootis type stars
E. Paunzen, G. Handler, W. W. Weiss +7
The group of lambda Bootis type stars comprises late B- to early F-type, Population I objects which are basically metal weak, in particular the Fe group elements, but with the clea…
Discovery and analysis of p-mode and g-mode oscillations in the A-type primary of the eccentric binary HD 209295
G. Handler, L. A. Balona, R. R. Shobbrook +8
We have discovered both intermediate-order gravity mode and low-order pressure mode pulsation in the same star, HD 209295. It is therefore both a Gamma Doradus and a Delta Scuti st…
ROSAT PSPC spectra of X-ray selected Narrow Emission Line Galaxies
E. Romero-Colmenero, G. Branduardi-Raymont, F. J. Carrera +4
We analyse the ROSAT PSPC spectrum of 19 X-ray selected Narrow Emission Line Galaxies (NELGs) discovered during the optical identification of sources in the ROSAT UK Deep Survey. T…
