Centaurus A (or Cen A for short) is a typical elliptical galaxy. Its unusual name comes from radio astronomy; Centaurus A was the first source of radio waves found in the constellation Centaurus.

ELLIPTICAL GALAXY
An elliptical galaxy is a galaxy that has the shape of an ellipse. It is also called an "E" or "E-type" galaxy. M87 and M32 are elliptical galaxies.
Elliptical Galaxy: A galaxy classification in the Hubble scheme, ellipticals get their names from their overall shape. The ellipticals are subclassified by their degree of ellipticity as they appear to the observer.

The Hubble classification system rates elliptical galaxies on the basis of their ellipticity, ranging from E0, being nearly spherical, up to E7, which is highly elongated.
elliptical galaxy a galaxy with a smooth, rounded appearance. Early large burst of star formation long ago used up all of their original gas and dust.
An elliptical galaxy has all of the material moving in a swarm about the center, while a spiral has a well organized disk that is rotating. Why are they different? One of the reasons that things may move the ways they do is angular momentum.
One of the best ways of determining the mass of a system, such as a cluster of galaxies, group of galaxies or a massive elliptical galaxy, is to measure the X-ray temperature and gas profiles.
Eventually both galaxies will have merged completely, streams of gas and dust will be flying through the space near the newly formed giant elliptical galaxy.
A long time-exposure (Figure 25.5a) shows a large fuzzy ball of light"a fairly normal looking type E1 elliptical galaxy whose full extent is about 100 kpc across (considerably larger than the view shown in the figure).

Classification of an elliptical galaxy image is straightforward, because there is so little structure present. Types E0-E7 are recognized, where the number gives the projected axial ratio.
Hot gas around a giant elliptical galaxy glows blue and purple in this composite image from two space-based observatories. The background image, which shows individual galaxies, is from Hubble Space Telescope.
Our own galaxy (the Milky Way) has a tiny satellite galaxy (the Sagittarius Dwarf Elliptical Galaxy) which is currently gradually being ripped up and "eaten" by the Milky Way.
The Sagittarius Dwarf Elliptical Galaxy is a loop-shaped galaxy and one of the closest satellite galaxies of the Milky Way. It contains at least four globular star clusters.
For their investigation, the team studied 14 globular clusters in the large elliptical galaxy Centaurus A (NGC 5128) using the 6.5-m diameter Magellan Clay telescope at Carnegie's Las Campanas Observatory, Chile.
Elliptical galaxies: The galaxy in the photo is M87, a typical elliptical galaxy. They usually consist of old stars. Some dwarf ellipticals have as few as 10 million stars, and make them not much different from a large globular cluster.
The best known ones are spiral galaxies Messier 65, Messier 66, Messier 95, Messier 96 and elliptical galaxy Messier 105. Messier 65 (NGC 3623) is 22 million light-years away.
Here we find another elliptical galaxy NGC 4216. At magnitude 10, it is the dimmest of this week's objects. This galaxy may appear dim, but it appears a respectable 8.3 arcminutes, or 1/7 of a degree across.
M110 (NGC 205) is another elliptical galaxy, and a larger companion to M31 but much dimmer. It lies about thirty-five arc-minutes NW of M31.

The second-brightest star (Beta Leo) is Denebola (meaning "tail of the lion"), and the third-brightest star (Gamma 1 Leo) is Algieba (meaning "forehead"). The spiral galaxies M65, M66, M95, M96, and the elliptical galaxy M105 are nearby.
the gas and dust in the colliding galaxies, causing shock waves that can trigger some star formation in the galaxies. These processes can radically affect the colliding galaxies, e.g., two spiral galaxies can merge to form an elliptical galaxy.
