Published Papers
Miscellaneous :

Landi et al. 2007 :
  • USNO B1.0 counterpart with R=15.28-15.66
  • Also listed in 2MASS
  • Spectrum has NH=2e22 cm-2, and a power law with Γ=0.8 or 1.8. 2-10 keV flux = 2.4e-12 erg/cm2/s

Tomsick et al. 2009 :
  • Chandra observation
  • Diffuse source (CXOU J174453.4-323254)
  • Spectrum (extension 3')= absorbed powerlaw, NH=2.5 x 1022 cm-2, Γ=1.27
  • A point source is detected at the edge of the diffuse emission

Curran et al. 2011 :
  • IR observations and reanalysis of Swift
  • Infra red counterpart to the source discovered KS = 14.03
  • Present SED that is consistent with a single power law over 5 order of magnitudes in frequency
  • Source not associated to the extended source (CXOU J174453.4-323254)
  • Point source likely a blazar seen through the Galactic plane

Barrière et al. 2014 (ApJ):
  • Analysis of a 43 ks XMM-Newton observation
  • Extended emission = massive galaxy cluster hidden behind the Galactic plane
  • zcluster~0.055
  • Confirm bright point source = blazar
  • Blazar either a flat spectrum radio quasar or a low freq. peaked BL Lac
  • IGR = Galaxy Cluster up to ~ 45 keV and Blazar above
