INTEGRAL discovers a new millisecond pulsar
During the observations of the Galactic Bulge during September 12, 2009, INTEGRAL discovered a new bright hard X-ray source, which was designated IGRJ17511-3057.
The source is detected in the INTEGRAL/IBIS mosaic image with a significance of 14 sigma in the 20-40 keV energy band, and 7 sigma in the 40-80 keV energy band. The corresponding count rates in these bands are 4.2+/0.3 cts/s (28 mCrab) and 1.8+/-0.3 cts/s (25 mCrab), respectively. The source is also detected in the JEM-X mosaic in the three energy bands 3-7 keV, 7-11 keV, and 11-20 keV. The source flux is ~20 mCrab and the detection significance is 3 sigma in all bands.
No previously known X-ray source was found within the INTEGRAL error circle.
