During the start of the third period of the INTEGRAL Galactic Bulge monitoring observations (Kuulkers et al 2005, ATel #438), the X-ray transient and black-hole candidate XTE J1817-330 (ATel #714)...
Further INTEGRAL observations of IGR J17497-2821 (2006)
Shaw, S.E., Soldi, S., Mowlavi, N., Kuulkers, E., Brandt, S., Chenevez, J., ...
The new INTEGRAL source IGR J17497-2821 (ATel #885) has been clearly detected by IBIS/ISGRI (S/N=33, 20-60 keV) in the INTEGRAL Galactic bulge monitoring program (ATels #438, #874) on 2006, Sep 18,...
The INTEGRAL Galactic Bulge monitoring program (2006)
Kuulkers, E., Shaw, S.E., Brandt, S., Chenevez, J., Courvoisier, T.J.L., Ebisawa, K., ...
The Galactic Bulge region is a rich host of variable high-energy point sources. These sources include bright and relatively faint X-ray transients, X-ray bursters, persistent neutron star and...
Kuulkers, E., Shaw, S.E., Paizis, A., Gros, A., Chenevez, J., Sanchez-Fernandez, C., ...
We performed a re-analysis of all consolidated data of the INTEGRAL AO-3 Galactic Bulge monitoring program (ATel #438; Kuulkers et al. 2006, astro-ph/0603130), and detected a new source with...
INTEGRAL and RXTE monitoring of XTE J1817-330: evolving through a state change? (2006)
Kuulkers, E., Goldoni, P., Shaw, S.E., Brandt, S., Chenevez, J., Courvoisier, T.J.L., ...
INTEGRAL Galactic Bulge monitoring observations (ATel #438) indicate that the X-ray transient and black-hole candidate XTE J1817-330 (ATel #714) has increased in hard X-rays (20-60 keV) compared to...
Broadband INTEGRAL analysis of IGR J17497-2821 (2006)
Kuulkers, E., Chenevez, J., Shaw, S.E., Brandt, D., Courvoisier, T.J.L., Garau, A.D., ...
We further analysed the INTEGRAL JEM-X observations performed on UT 2006, Sep 18, 08:30-12:12 (ATel #886) of the new hard INTEGRAL source IGR J17497-2821 (ATel #885). We find average fluxes of 31 +/-...
