Characteristics

This galaxy was first described by using an X-ray [[Spectro-Polarimetric High-Contrast Exoplanet Research |spectro-polarimetric analysis]] the galaxy was describe as a extremely bright Seyfert galaxy of the width of H-alpha (13,000 km/sec) and the high H-beta luminosity. This galaxy is described as edge-on spiral close to a elliptical galaxy IC 4329, which is the brightest galaxy inside a galaxy cluster in the Centaurus region.[5] It has a dust lane displaying extreme polarization.[6]

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.[7]

The supermassive black hole in IC 4329A is estimated to be 6.8+1.2-1.1 x 107 Mʘ.[8]

The closest galaxy next to IC 4329A is IC 4329 with the group of IC 4327, 5302, 5304, 5298, PGC 159482 and PGC 48950.[9]
