Cette contribution retrace l’ascension politique d’Annegret Kramp-Karrenbauer (AKK). Ayant gravi un à les échelons de la politique, cette femme conservatrice sarroise a assumé, depuis années 1980, divers mandats et fonctions dans parlements gouvernements ainsi que son parti, l’Union chrétienne-démocrate (CDU) dont elle été présidente. Son parcours qui aurait pu mener chancellerie livre exemple ...

Optical positions relative to the International Reference Stars Catalogue (IRS), and therefore in the system of the FK5, have been obtained for the optical counterparts of 40 compact extragalactic radio sources south of δ ∼ +6◦. Many of these sources are being considered as possible Benchmark objects for the establishment of a quasi−inertial unified radio/optical reference frame. Precision leve...

In this paper we test the hypothesis that the Pioneer anomaly can be of gravitational origin by comparing the predicted model-independent shifts ∆a/a for the semimajor axis of Uranus and Neptune with the Voyager 2 radio-technical distance measurements performed at JPLNASA. As in the case of other tests based on different methods and data sets (secular perihelion advance, right ascension/declina...

We examine the H I content of spiral galaxies in groups by using a catalog of loose groups of galaxies identified in a magnitude limited sample (mZ ≤ 15.7) spanning the range 8 ≤ α ≤ 18 in right ascension and +9 ≤ δ ≤ +15 in declination. The redshift completeness of the galaxy sample is ∼ 95%. No significant effect of H I depletion is found, although there may be a hint that the earliest type s...

AB S TRACT The optical counterparts of 23 extragalactic radio sources, of which 13 are in the southern hemisphere, have been observed by three telescopes equipped with CCDs. By reference to the Astrographic/Tycho (ACT) Reference, Carlsberg Meridian (CMC), Positions and Proper Motions (PPM), Hipparcos (HIP) and Lick Northern Proper Motion (NPM) catalogues, the positions of the 23 objects have be...

In NightDriving, a semi-transparent projection scrim filling the width and height of the stage brings real and virtual dancers into the same field of view. The resulting shared visual space contains two kinds of representation: a “here and now” embodiment of the dance through the live performers, and projected dance film imagery of virtual figures in counterpoint to the live dancers. This share...
