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...

The heavenly ascent motif is common in religious documents of late antiquity. A preoccupation with the similarities between these accounts leads some to overlook the equally important differences. Care should be taken, however, to distinguish between mystical esotericism and extraordinary religious encounter. Earlier Jewish traditions provide the proper context for understanding Paul's visions ...

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...
