OGLE2-TR-L9: An extrasolar planet transiting a fast-rotating F3 star
I. A. G. Snellen, J. Koppenhoefer, R. F. J. van der Burg +7
Context: Photometric observations for the OGLE-II microlens monitoring campaign have been taken in the period 1997-2000. All light curves of this campaign have recently been made p…
Head-Tail Galaxies: Beacons of High-Density Regions in Clusters
Minnie Y. Mao, Melanie Johnston-Hollitt, Jamie B. Stevens +1
Using radio data at 1.4 GHz from the ATCA we identify five head-tail (HT) galaxies in the central region of the Horologium-Reticulum Supercluster (HRS). Physical parameters of the…
First-Forbidden Continuum- and Bound-State beta^- -Decay Rates of Bare 205Hg80+ and 207Tl81+ Ions
M. Faber, A. N. Ivanov, P. Kienle +3
We calculate the decay rates lambda_(beta^-_c) and lambda_(beta^-_b) of the continuum- and bound-state beta^- decays for bare 205Hg80+ and 207Tl81+ ions. For the ratio of the decay…
Optical identification of a new cataclysmic variable from integral all sky survey: IGR J08390--4833
M. Revnivtsev, A. Kniazev, S. Sazonov +6
We have optically identified a recently discovered INTEGRAL source, IGR J08390--4833, with a cataclysmic variable, i.e. an accreting white dwarf in a binary system. The spectrum ex…
Beam Performance of Tracking Detectors with Industrially Produced GEM Foils
Frank Simon, James Kelsey, Michael Kohl +7
Three Gas-Electron-Multiplier tracking detectors with an active area of 10 cm x 10 cm and a two-dimensional, laser-etched orthogonal strip readout have been tested extensively in p…
High redshift quasars in the COSMOS survey: the space density of z>3 X-ray selected QSOs
M. Brusa, A. Comastri, R. Gilli +19
We present a new measurement of the space density of high redshift (3.0<z<4.5), X-ray selected QSOs obtained by exploiting the deep and uniform multiwavelength coverage of the COSM…
