Miscellaneous :

Landi et al. 2007 ATel 1288:
  • Association with SUMMS and 2MASS sources
  • probable AGN
  • Unabsorbed power law Γ=2.1
  • 2-10 keV flux= 1.1x10-12 erg/s/cm2
Masetti et al. 2008:
  • Optical spectroscopy is presented and detailed
  • Fluxes of Hβ and [OIII] are given
  • Sey 1.2 at z=0.052
  • MBH=62 x 107 Msun
Zhang et al. 2009 (A&A):
  • Detect the source in 1.4 Ms of INTEGRAL data with σ20-60 keV=9.4 sigma
  • Source is therefore a real source
  • Confirm the proposed associations with a Swift X-ray source and a Sey 1.2 AGN.
  • Rather steady in flux at hard X-rays, while it shows up to 39 % flux variations at soft X-rays
  • Joint XRT-ISGRI spectrum well fitted by an absorbed power law: NH=8.73 x1020 cm-2; Γ=2.11.
