Published Papers
Miscellaneous :

Kuiper et al. 2006 ATel 939:
  • ~0.6 mCrab in 20--60 keV
Masetti et al. 2006ATel 939:
  • 2 point like sources in Rosat error
  • Lack of Balmer or He emission line=> not associated with X-ray sources
    Landi et al. 2007ATel 1322:
    • Swift : 2 point like sources in INTEGRAL error
    • First most likely counterpart to the hard source
    • NH ~1022 cm-2, power law spectrum Γ~1.8, 2-10 keV flux = 6.7 x 10-12 erg cm-2 s-1
    • 2nd has no count above few keV, Rosat counterpart
    Jonker & Kuiper 2007ATel 1326:
    • Chandra refined pposition => 2MASSJ00331833+6127432 (J=15.665, H=14.379, K=13.081) as the probable IR counterpart (disagreement with Landi et al. ATel 1322)
    • source is a probable symbiotic XRB
    Parisi et al. 2008ATel 1375:
    • optical spectra
    • Source 1 is the counterpart (not 2 as favoured by Jonker and Kuiper
    • Very broad Halpha+[NII] complex and narrow [OIII] lines
    • Redshift z=0.105+-0.001
    • IGR J00333+6122 is the X-ray counterpart to USNO-A2.0 1500_00589511 = Seyfert 1 AGN
    • Source 2 is TYC 4015-206-1 = star of intermediate spectral type
    • Not a symbiotic X-ray binary, but a star with coronal emission
    Masetti et al. 2009:
    • optical spectra
    • Source is a Sey 1.5
    • VBLR=8100 km/s and MBH=35 107 MSUN
