... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...

Ref: ALMA band 1 horn measures Date: 27/08/2002 Technical note ALMA band n.1 horn measurements Author: Renzo Nesti Summary This document is intended to give pattern and return loss measurements of the ALMA band n.1 horn (31.3-45 GHz) produced by CLOEMA and designed by MECSA and Arcetri. ... Because the measurements have been made by rotating the horn under test on the expected phase centre we conclude that the estimation of the phase centre position does agree well with tests. ...
