Miscellaneous :
Gibaud et al. 2011ATel 3565:
  • INTEGRAL discovery=> IBIS spectrum well fitted by a power law with Γ=2.6
  • Globular cluster NGC 6388 within IBIS error box
Ferrigno et al. 2011ATel 3566:
  • Swift pointed observation => source is within the Globular Cluster NGC 6388
  • X-ray spectrum well represented by absorbed power-law with Γ~ 0.7 and NH<2.6 x1021 cm-2.
  • Difference of IBIS and XRT spectral slopes suggest turn over typical of LMXBs and accreting binaries
Wijnands et al. 2011ATel 3595:
  • Swift monitoring => source flux ~constant over 9 days
  • Source is a very faint X-ray transient
  • Possibly a neutron star LMXB, or intermediate mass black hole
Ferrigno et al. 2011 ATel 3617& Bozzo et al. 2011(A&A):
  • No hint of radio emission was found with ATCA within 4 arcmin with RMS noise levels of 14.1 muJy, 19.0 muJy, 20.0 muJy, and 21.2 muJy at respectively 5.5, 9, 17, and 19 GHz
  • Fits to the 0.5-100 keV spectrum (Swift/INTEGRAL)=> absorbed black body plus a cut off power law (Nh=0.8e22 cm-2, Gamma=1.0, Ecut=24 keV, kTbb=0.08 keV)
  • Radio-X-ray fundamental plane =>not associated with the IMBH
  • Black hole nature not favoured.
Pooley et al. 2011ATel 3627:
  • Chandra observations => refined position
  • 2.7" from the centre of the Globular cluster => not associated to IMBH
  • not associated to any previously known source in the cluster
  • quiescent luminosity (from previous and deeper obs) => 1e31 erg/s
Nucita et al. 2012 (New Astr.):
  • XMM slew observations
  • Spectral analysis => slight evolution of Γ compared to Swift
  • Discussion about nature of the source, LMXB preferred
Del Santo et al. 2014 (MNRAS):
  • Analysis of 200 days Swift/XRT observations
  • Light curve shows a t-5/3 trend + thermal emission with no significant variations with time
  • Investigate the possibility of a tidal disruption event
  • In this case estimate accretion efficiency consistent with a massive white dwarf.
  • Obtained mass of the disrupted body and the accretion efficiency => inner disc temp 0.04 keV constistent with the value obtained from the spectral fits
Bozzo et al. 2014 (A&A):
  • Analysis of XMM-Newton observation
  • Spectral modeling compatible with that of Swift/RXTE, in particular confirm the presence of 0.08 keV thermal component
  • Discovery of 100 mHz qQPO
  • Data compatible with TDE although other possibilities cannot be completely ruled out
  • Light curve shows a t-5/3 trend + thermal emission with no significant variations with time
  • Investigate the possibility of a tidal disruption event
  • In this case estimate accretion efficiency consistent with a massive white dwarf.
  • Obtained mass of the disrupted body and the accretion efficiency => inner disc temp 0.04 keV constistent with the value obtained from the spectral fits
