R.A. (J2000) Dec. (J2000) References R.A. (J2000) Dec. (J2000) References
probable AGN, but HMXB possible
Published Papers
Miscellaneous :
Bodaghee et al. 2012 (ApJ):
  • XMM observation => refined position
  • 2MASS J18454039+0242088 nearest IR counterpart is just outside the XMM error box
  • Power law fit to spectrum => NH=84e22 cm-2; Γ=2.3
  • Possible redshifted iron line at 6.01 keV would imply z=0.07 and a luminosity 9e43 erg/s
  • Possible 4.4 ks QPO
  • QPO and line => probable AGN, but since both feature are to be confirmed HMXB not totally ruled out
