... 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. ...

The 24-inch (0.6-meter) Ritchie-Chretien research telescope was manufactured by RC Optical Systems and installed in August 2006. ... Spacers are used to put the camera or other instruments at the proper position, and an encoded focus motor moves the focal plane 5 microns per encoder count. ... The telescope uses an Apogee U16M CCD camera with a 4096x4096 array of 9 micron pixels which oversample the seeing and permit very accurate photometry and imaging over a wide dynamic range. ...

... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

Other galaxies are not moving away because they are recoiling in disgust from the Milky Way, but appear to be receding because the Universe is expanding. ... Observers in any galaxy will see every other galaxy as redshifted, so there is nothing special about the Milky Way. ... If the Universe is expanding today, that implies that in the past the galaxies would have been closer together and the Universe was much smaller than it is now. ...
