The group may be roughly divided into two subgroups. NGC 5128 is fundamentally a giant E galaxy “NGC 5128 is an unresolved E0 nebula with an unusually strong and wide central absorption band … The curvature of the outer parts of the spiral system and the irregular distribution of the absorbing clouds …clearly indicate … We show that the integrated colour U - B can be an effective metallicity indicator for simple stellar populations. M83, also known as the Southern Pinwheel Galaxy, ... which also includes peculiar radio galaxy Centaurus A (NGC 5128) and unusual galaxy NGC 5253.

1 Independent Component Analysis for the objective classification of globular clusters of the galaxy NGC 5128

This makes M83 a popular target for amateur supernovae hunters. classification is applied to galaxies which are often very different from each other and van den Bergh (1990) ... Galaxy type for NGC 5128 Galaxy type Source Like NGC 3379 (E1) Se´rsic (1958) E0p Morgan (1958) (E0þSb) Sandage (1961) S0p Freeman (1970) E0p van den Bergh (1976) Eþspiral Dufour et al. We present high spatial resolution near-infrared spectra and images ofthe nucleus of Centaurus A (NGC 5128) obtained with NAOS-CONICA at theVLT. Image Details.

NGC 5128 is the fifth brightest galaxy in the sky and one of the strangest looking galaxies in the nearby universe.

Some categorise it as elliptical, while others think it is a lenticular galaxy. Credit: Mirabel et al. The M83 Subgroup, at a distance of 14.9 Mly (4.56 Mpc), is centered on the Messier 83 (M83), a face-on spiral galaxy. Whereas ICA finds a set of source data that are mutually independent, PCA finds a set of data that are mutually uncorrelated. 57, No. When most people look at NGC 5128 they see a peculiar galaxy dominated by a prominent dust lane and ignore the rest. Title: Star Formation Efficiencies at Giant Molecular Cloud Scales in the Molecular Disk of the Elliptical Galaxy NGC 5128 (Centaurus A) There are still uncertainty about numerous properties of the galaxy, including its morphological classification or its distance. What I see is a nearby E galaxy whose oldest stars can tell us a great deal about its history. The NGC 5128 Group. When observing the galaxy, it's not a bad idea to compare the view … Home Browse by Title Periodicals Computational Statistics & Data Analysis Vol. 1991 ; Schreier et al. NGC 5128, Centaurus A Galaxy. Below - two large galaxies in the NGC 5128 group.

Independent Component Analysis (ICA) is closely related to Principal Component Analysis (PCA) and factor analysis.

Downloadable (with restrictions)! With V = 6.98 mag (de Vaucouleurs et al., 1976 - RC2), NGC 5128 is the fifth brightest galaxy in the sky, immediately after the Local Group members M 31, M 33, LMC and SMC.Images of relatively short exposure, limited to a surface brightness in B of about 22 mag per arcsec 2, show an almost circular appearance, which has led to the classification S0p or E0p (). The collision resulted in a burst of star formation. NGC 5128 Peculiar Galaxy NGC 5128 (= Dunlop 482 = Arp 153 = Bennett 60), type Pec, in Centaurus. Overview. NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194).

Designated as radio source Centaurus A, NGC 5128 is one of the most peculiar galaxies in the sky. Image Details. The blue regions toward the top are thought to be areas of star formation induced by powerful jets originating from a central black hole. THE NEARBY E GALAXY. NGC 5128 (Centaurus A) - Lenticular Galaxy is classified as Lenticular (S0) according to the Hubble and de Vaucouleurs galaxy morphological classification. This galaxy is situated in the M83 group of galaxies. This unusual galaxy is believed to be the result of a collision of two normal galaxies. 1979 ) and an unresolved nucleus that appears longward of 2 m ( Turner et al. , A&A , 341, 667, 1999. Centaurus A has the designation NGC 5128 in the New General Catalogue. THE GALAXY. The adaptive optics-corrected data have a spatial resolution of0.06" (FWHM) in K and 0.11" in H band, 4 times higher than previousstudies. It is bisected by a dark lane that is considered the dust remnant of a smaller spiral galaxy that was cannibalized by the larger elliptical galaxy. Right Ascension: 13 : 25.5 (h:m) Declination-43 : 01 (deg:m) Distance: 15000.0 (kly) Visual Brightness: 7.0 (mag) Apparent Dimension: 18 x 14 (arc min) Discovered by James Dunlop in 1826. The Cen A Subgroup, at a distance of 11.9 Mly (3.66 Mpc), is centered on Centaurus A, a nearby radio galaxy.
