MAXI/GSC detection of X-ray enhancement toward the globular cluster Tarzan 1
Abstract
At 23:18 UT on May 24th, 2013, the MAXI/GSC auto-detection system triggered X-ray enhancement at the position consistent with the globular cluster Terzan 1. We have confirmed that the X-ray flux has gradually increased from around May 19th, 2013 (MJD 56431), and still remains stable on timescale of days at the 4-10 keV flux of about 8 mCrab. The central position of the enhanced region in the smoothed 2-20 keV image, obtained from May 19th to May 30th, is (R.A., Dec) = (263.84, -30.48) with a typical uncertainty of 0.3 deg.
