... 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. ...

We note, with deep sorrow, that Dr. Valentin Alexandrovich Lipovetsky, a senior astronomer and the leader of the Laboratory of Galaxy Studies of the Special Asrtrophysical Observatory, passed away at the age of 51 on September 22, 1996, after a several year battle with melanoma. Valentin Lipovetsky was an outstanding astronomer in many areas of extragalactic research and an internationally acknowledged leader in objective prism surveys and studies of AGN and star-forming galaxies. ...
