... 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 project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

... We received the SASS output for the HRI observation of 3C 120 (a highly variable radio galaxy with a prominent jet leaving the core at PA ) and smoothed the data with a Gaussian of FWHM = 3 '' ( Figure 13.1 ). ... The results are shown in Figure 13.2 . ... The FWHM of the original data ( Figure 13.1 ) is 11.8 (PA ); after dewobbling ( Figure 13.2 ) the width of the 50% contour is 7.6 . ... Figure 13.1 : The original data, smoothed with a Gaussian of FWHM = 3 . ...

STScI-PRC99-10 . ... Astronomers have used the NASA Hubble Space Telescope to produce an infrared "photo essay" of spiral galaxies. By penetrating the dust clouds swirling around the centers of these galaxies, the telescope’s infrared vision is offering fresh views of star birth. These six images, taken with the Near Infrared Camera and Multi-Object Spectrometer, showcase different views of spiral galaxies, from a face-on image of an entire galaxy to a close-up of a core. ...
