... January 21, 1997 . Journey to the Center of the Galaxy . ... What wonders lie at the center of our Galaxy ? Astronomers now know of some of the bizarre objects which exist there, like vast dust clouds , bright young stars , swirling rings of gas , and possibly even a large black hole . ... The center itself appears as a bright spot near the middle of the roughly 1x3 degree field of view, the plane of the Galaxy is vertical, and the north galactic pole is towards the right. ...

Properties of NGC 1530 and observational results . ... Then in a frame rotating with the potential, the periodic orbits are ellipses either parallel to the bar ( ) or perpendicular ( ), depending on the radius of the orbit. ... We observed the molecular gas in the bar of NGC 1530, a barred SBb spiral in the line. ...

... Astronomy news . ... NASA's Spitzer Images Out-of-This-World Galaxy . ... It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white. ... The ring around the black hole is bursting with new star formation. ...

The NICMOS team has devised a comprehensive program of observations of the Galactic Center. ... Data in hand give a first look at variability and a detailed look at the search for the tip of the main sequence will be discussed where NICMOS has demonstrated adequate sensitivity and photometric precision to identify likely O8-B1 stars at the Galactic Center. ...

... ROTATION CURVE: When studying spiral galaxies it is invariably found that the stellar rotational velocity in the disk remains constant, or "flat", with increasing distance away from the galactic center. ... By the same argument the flat galactic rotation curves seem to suggest that each galaxy is surrounded by significant amounts of dark matter. ... What is the maximum rotation velocity and the total amount of mass (including dark matter) in the galaxy as a function of radius. ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...

Small Galaxy Groups ASP Conference Series, Vol. ... It is generally accepted that they are related to the nuclear rings formed in barred galaxies at the inner Linblad resonance (ILR), although according to Buta and Crocker (1993), in some cases they were found in non-barred spirals, so in general a presence of large-scale non-axisymmetric gravitational potential is not a rigid condition for the nuclear bar to be formed. Typical length of nuclear bars is 1 - 2 kpc for H 0 = 75km=s=Mpc. ...

... A tussle in the distant Universe. This Hubble Space Telescope image shows evidence for a merger between a quasar and a companion galaxy. The quasar is the bright object just beneath the image center, and the wisps of material around it are remains of a galaxy disrupted by the interaction between it and the quasar. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...
