The microlensing event OGLE-2008-BLG-510 is characterised by an evident asymmetric shape of the peak, promptly detected by the ARTEMiS system in real time. The skewness of the light curve appears to be compatible both with binary-lens and binary-sour

Massive quiescent galaxies at z>1 have been found to have small physical sizes, hence to be superdense. Several mechanisms, including minor mergers, have been proposed for increasing galaxy sizes from high- to low-z. We search for superdense massive

The Orientation of Danish Passage Graves

Publikováno v: Acta Archaeologica. 79:216-229

We have measured the directions of the entrance passages for 51 passage graves situated mainly on north Zealand. Together with previously published measurements, the combined sample of 105 entrance directions shows a strong preference for the azimuth

We report on the implemented design of a two-colour instrument based on electron multiplying CCD (EMCCD) detectors. This instrument is currently installed at the Danish 1.54m telescope at ESO's La Silla Observatory in Chile, and will be available at
