Published Papers
Miscellaneous :
Stephen et al. 2010 ATel 2441:
  • cross correlation IBIS position, XMM-SL and/or Rosat survey
  • Alignment with G32.1-0.9 is coincidental
  • Possible distant Galactic source or bgd AGN
Halpern & Gotthelf 2010 ATel 2445:
  • XMM observation
  • X-ray spectrum fitted with a power-law model Γ=1.7, NH = 1.5 x1022 cm-2.
  • Object in 2MASS Point Source Catalog with H=14.00 and K=12.50
Malizia et al. 2010:
  • XMM observation combined with IBIS spectrum
  • NH=0.4x1022 cm-2, power law Γ=1.56
  • possible background AGN
Lutovinov et al. 2012 (Astr. Lett.):
  • Optical observations
  • Sey 1 at z=0.145
Bodaghee et al. 2012 (ApJ):
  • XMM observation => refined position
  • X-ray position closer to the Optical counterpart identified as an AGN
  • X-ray spectrum => absorbed power law NH~ 2e22 cm-2, Γ=1.57
  • Consistent with AGN classification
