Characteristics
[edit]This galaxy was first described by using an X-ray spectro-polarimetric analysis as an extremely bright Seyfert galaxy on account of the width of H-alpha (13,000 km/sec) and the high H-beta luminosity. This galaxy is described as an edge-on spiral galaxy close to elliptical galaxy IC 4329, which is the brightest galaxy inside a galaxy cluster in the Centaurus region.[6] It has a dust lane displaying extreme polarization.[7]
Additionally, dust components in IC 4329A have been detected mainly in the interstellar medium of its host galaxy as well as its nuclear component located in the active torus.[8]
The supermassive black hole in IC 4329A is estimated to be 6.8+1.2
−1.1 x 107 Mʘ.[9]
