Abstract
dc.description.abstract
We present high spatial resolution X-ray Chandra HRC and HST WFPC2 Ha observations of
the prototypical infrared-luminous galaxy NGC 6240. The central region of this system
shows a remarkably complex morphology, with filaments and loops observed in the optical
and X-rays. The total X-ray luminosity is dominated by the extended emission. Both nuclei
are clearly detected in the HRC image and both appear to be extended. The energetics of the
nuclei imply that the southern nucleus is the more plausible counterpart to the obscured active
galactic nucleus. The overall spectral energy distribution of the galaxy is in good agreement
with a blend of starburst and AGN components that have similar bolometric luminosities,
Lbol , 5 £ 1045 erg s21, with the starburst dominating the observed continuum in the nearinfrared
(K band), optical and soft X-ray bands.
