The NGC 5128 young GCs do not contribute to this trend. UKS 32a: The field of NGC 5128 (Centaurus A, portrait format) - big image The bright blue-green star in the middle of the left part of the dust belt in this image is supernova 1986G (the only SN discovered in Centaurus A so far) which was discovered on May 3, 1986, by Reverend Robert Evans, and reached mag 12.5 (see IAUC 4208). The Centaurus A/M83 Group is a complex group of galaxies in the constellations Hydra, Centaurus, and Virgo.The group may be roughly divided into two subgroups. NGC 5102 (centre) is a lenticular galaxy. Historical Identification: Per Dreyer, NGC 500 (= GC 290, 3rd Lord Rosse, 1860 RA 01 15 23, NPD 85 20.3) is "very faint, very small, much brighter middle, 11th magnitude star 1 arcmin to northeast". The NGC 5128 GC system shows strong bimodality in the optical R band to mid-IR colour distributions, hence proving it is bimodal in metallicity. The Cen A Subgroup, at a distance of 11.9 Mly (3.66 Mpc), is centered on Centaurus A, a nearby radio galaxy. NGC 5068 (left) is a small spiral galaxy which lies about 20 degrees to the north of the centre of the group. Centaurus A – NGC 5128 Constellation: Centaurus Type: S0 pec or Ep Coordinates: 13h 25m 27.6s (right ascension), -43°01’09” (declination) Distance: 10 – 16 million light years (3 – 5 Mpc) Apparent magnitude: 6.84 Apparent dimensions: 25′.7 x 20′.0 Below - three more galaxies in the NGC 5128 group. Because of NGC 5128's low Galactic latitude (19°) we see it through the Milky Way halo and disk and its mainly late type stars whose colours and apparent magnitudes will fall in the same range as GC candidates.
This change using the color index to obtain a visual magnitude estimate would also change the ranking order in some cases. The NGC 5128 young GCs do not contribute to this trend.
Description M87 NGC 5128 ITRGB [mag] 27 24 Distance [Mpc] 16.7 3.8 ... limiting apparent magnitude of I = 29
Its brightest GCs should appear at an apparent magnitude of V ~ 17 while the peak of the GC luminosity function (GCLF) would be seen at a magnitude of V ~ 21. It is gravitationally bound into a group of galaxies which also contains Messier 83. In this new colour space, a colour-magnitude trend, a `blue tilt', is found in the NGC 5128 metal-poor GC data. NGC 3147 is a spiral galaxy located in the constellation Draco.
The star exhibits variations in brightness due to non-radial gravity wave pulsations within itself. The color indices for galaxies vary from around 0.45 (M101 for example) to as high as 1.0 (NGC 5128) depending on the galaxy. Photometric information of NGC 5128. In this new colour space, a colour-magnitude trend, a “blue tilt”, is found in the NGC 5128 metal-poor GC data. Apparent magnitude (central regions) m B = 7.96 m V = 6.98 Location. It was discovered by William Herschel on … Centaurus A, also known as NGC 5128, is a peculiar galaxy in the constellation of Centaurus.
