Kuulkers et al. 2007 (A&A):
  • ISGRI spectrum can be described by a powerlaw with index 2.2.
  • The non detection by JEM X, if due to absorption, implies Nh>1e23 cm-2
Kuulkers et al. 2007 ATel 1005:
  • active on Feb 15 2007 between 18:35 and 22:17 UTC
  • ~11 mCrab between 20-60 keV, <5 mCrab in 3-10 and 10-25 keV
Kuulkers et al. 2007 ATel 1008:
  • Possibility of association of IGR J17453-2853 and GRS 1741.9-2853
  • Spectrum of GRS 1741.9-2853 is consistent with the 20-60 keV flux measured with INTEGRAL.
  • Both sources were active at the same time in April 2005.
Muno et al. 2007 ATel 1013:
  • Association of IGR J17453-2853 and GRS 1741.9-2853 strengthened
  • Chandra spectrum of GRS 1741.9-2853 is powerlaw with Gamma=0.9
  • NH=9.0 x 1022 cm-2
  • 2-8 keV flux 3e-11 erg cm-2 s-1 <=> for D=8 kpc estimated intrinsic 2-8 keV luminosity of 4 x 1035 erg s-1.
Porquet et al. 2007 ATel 1058:
  • XMM source location compatible with those of CXOGC J174502.3-285450, AX J1745.0-2855, and GRS 1741.9-2853.
  • 2 X-ray bursts observed =>consistent with bursting behaviour of GRS 1741.9-2853
  • Outburst duration is at least 7 weeks for this transient.
  • Last XMM-Newton observation, April 3-4, 2007, XMM-Newton/EPIC count rate decreased by about factor of 2.5 in less than one day.
