Published Papers
Miscellaneous :
Rodriguez et al. 2010 ATel 2557:
  • UVW2 counterpart with m_UVW2=20.0, while USNO B1 source has m_I=15.6 m_R=15.1 m_B=16.8
  • Spectrum <=>absorbed power law parameters very poorly constrained. NH=19 x1022 cm-2, and Γ pegging at highest value allowed (3)
  • Source could possibly be an AGN.
Landi et al. 2010 ATel 2563:
  • Suggest SUMSS J135512.53-721916.2 ( 36 cm flux of 18.8 mJy) is the radio counterpart
  • SUMSS also suggested to be associated to PMN J1355-7219 which suggests a flat radio spectrum
  • Presence of 2MASX source consistent with the USNO B1.0
  • source is a probable AGN
Masetti et al. 2012 (A&A):
  • Optical spectroscopy of counterpart (aka LEDA 3075535)
  • Source is a Sey 2 at z=0.071
