| Kuiper et al. 2006 ATel 939: |
|
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
