In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

... Neutral hydrogen observations of the spiral galaxies NGC 6221 and NGC 6215 with the Australia Telescope Compact Array (ATCA) reveal a wide, two-stranded bridge of at least 3 x 10^8 Msun which can be traced between the two galaxies over a projected distance of 100 kpc. ... The color figure below shows the HI emission (blue) in the bridge velocity range overlaid onto an optical image. ... A tidal HI bridge is visible between NGC 6221 and its brightest neighbour, NGC 6215 (v_sys = 1555 km/s). ...

... The new emission line galaxies are listed in Table 2 containing the following information: . column 1: The object's IAU-type name with the prefix HS. column 2: Right ascension for epoch B1950. column 3: Declination for epoch B1950. ... The spectra of all emission-line galaxies are shown in the Appendix A. The results of line flux measurements are given in Table 4. ... column 1: The object's IAU-type name with the prefix HS. column 2: Observed flux (in 10 -16 ergs -1 cm -2 ) of the H 4861 ? ...

... 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. ...

Type of Galaxies. taken from the Hubble Atlas of Galaxies. These galaxies display no bright blue stars like those in the spiral arms of Sb, Sc, Irr, SBb, and SBc galaxies. ... The smooth texture of the photographic image. ... SBa - Galaxies possesss a characteristic bar that is prominent and smooth in texture with no trace of resolution into knots or stars. ... SBb - These galaxies have a well defined bar structure which is smooth in texture with no hint of resolution into stars. ...

One possible way for spiral galaxies to internally evolve would be for gas to flow to the center and form stars in a central disk (pseudo-bulge). ... In this paper we present radial profiles of stellar and 8 ЮМm emission from polycyclic aromatic hydrocarbons (PAHs) for 11 spiral galaxies to investigate whether the interstellar medium in these galaxies contains a central concentration above that expected from the exponential disk. ...

... 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. ...
