... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

Welcome to the Starburst and Galaxy Evolution website.

... 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. ...

Next: The peculiar galaxy NGC 4258: Up: Other Galaxies with HI Previous: Other Galaxies with HI . NGC 4151 is a weakly-barred spiral galaxy (type PSXT2). It is also one of the best-studied examples of a nearby active galactic nucleus (AGN), and one of the original nuclei noted by Seyfert (1943). ... large-scale H I structure of the galaxy which covers a velocity range of about 920-1080 kms -1 in emission and absorption; the galaxy is viewed nearly face-on ( ). ...

... AAS link ] . ... Our internal perspective makes it difficult to determine the spiral structure of our own galaxy. ... H I absorption, on the other hand, traces colder, denser gas that should be more confined in discrete clouds and perhaps discrete spiral arms. In addition, H I self-absorption (HISA) requires background H I emission at the same velocity as the foreground absorbing gas, thus introducing a much-needed constraint on the large-scale sightline geometry and kinematics. ...
