Miscellaneous :
Landi et al. 2007 ATel 1288:
  • Association with strong radio source
  • probable AGN
  • NH=2x1021 cm-2, Γ=1.8
  • 2-10 keV flux= 5.5x10-12 erg/s/cm2
Landi et al. 2009 A&A:
  • Optical observations and detected a counterpart with R=19.2
  • Several X-ray observations => some variability in this source: only the luminosity varies and not the spectral shape
  • AGN, probably a border line between radio quiet and radio loud
Butler et al. 2009:
  • Optical spectroscopy
  • Spectrum flat with one strong and broad emission line
  • If line is Hα => source is a Sey 1 at z=0.113.
Masetti et al. 2010:
  • Optical spectroscopy of counterpart
  • Strong redshifted broad emission line typical of AGN
  • Source is a Sey 1.5 at z=0.112
  • Vblr=4700 km/s, Mbh=12e7 Msun
