The Near-Infrared Surface Brightness Distribution of NGC4696
arXiv:astro-ph/0601665 · doi:10.1071/AS05037
Abstract
We present H-band observations of the elliptical galaxy NGC4696, the brightest member of the Centaurus cluster of galaxies. We have measured its light profile, using a two-dimensional fitting algorithm, out to a radius of 180 arcsec (37 h^{-1}_{70} kpc). The profile is well described by a de Vaucouleurs law, with an effective radius of 35.3 +/- 1.0 h^{-1}_{70} kpc. There is no need for the extra free parameter allowed by a Sersic law. Allowing for a variation of 0.3% in the sky level, the profile obtained is compatible with data from 2MASS. The profile shows no sign of either a truncation or an extended halo.
