Published Papers
Miscellaneous :
Bozzo et al. 2009 ATel 2185:
  • 20-100 keV ISGRI spectrum well described by a power-law with Γ~2.2
  • 20-100 keV flux = 1.2e-10 erg/cm^2/s
  • variability on few hours time scale
Bozzo et al. 2009 ATel 2188:
  • Swift/XRT spectrum : power law (Γ=1.9) or a black body (kT=0.5 keV) with no absorption.
  • Swift flux 50 times lower than that of INTEGRAL
  • 2MASS 16443770-5550454 has J=10.953, H=10.341 and Ks=10.175
  • USNO-B1.0 0341-0647474 has B2=12.95 R2=11.78, and I=11.00
  • optical and IR counterpart coincident within 1"
