The Missing CV Population: Results From An Objective Prism Survey
C. Tappert, T. Augusteijn, J. Maza
We present the results of a search for cataclysmic variables (CVs) in the Calan-Tololo survey. We detected a total number of 21 CVs, 12 of them are previously unknown objects. Our…
Circumnuclear structure and kinematics in the active galaxy NGC 6951
Enrique Perez, Isabel Marquez, Ignacio Marrero +5
A study is presented of the central structure and kinematics of the galaxy NGC 6951, by means of broad band B'IJK images and high resolution high dispersion longslit spectroscopy,…
The new complex gravitational lens system HE 0230-2130
L. Wisotzki, N. Christlieb, M. C. Liu +3
We report the discovery of the new gravitational lens system HE~02302130, a QSO at redshift consisting of at least five distinct components. Three of these are clearly…
The Distances to Five Type~II Supernovae Using the Expanding Photosphere Method and the Value of
Brian P. Schmidt Robert P. Kirshner, Ronald G. Eastman, Mark M. Phillips +4
We have used observations gathered at CTIO to measure distances by the Expanding Photosphere Method (EPM) to 5 Type II supernovae. These supernovae lie at redshifts from cz = 1100…
