... Galaxies in the Local Volume . ... Accurate distances are now available for the majority of these nearby galaxies, allowing us to visualise the Local Volume in 3D, study the local Hubble flow and its dispersion, the (baryonic) Tully-Fisher relation, the local star formation density, etc. Individual galaxies in the Local Volume can be studied in amazing detail across a large range of wavelengths (some stunning examples are compiled in the Multiwavelength Astronomy pages). ...

... 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. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

In 1974 astronomers discovered a bright radio source at the center of the Milky Way Galaxy, in the direction of the constellation Sagittarius. It was an unknown quantity then, but astronomers now know that the object is a supermassive black hole causing a maelstrom of activity at the galactic center. ...

Molecular clouds in the central 200 pc of the Galaxy (the Central Molecular Zone ) exhibit different (and more extreme) physical properties than those in the disk, yet because this is the closest galactic nucleus, detailed studies of this region can provide insight on galactic nuclei in general in the nearby universe. ...
