- NICER ATEL: Observation of Fast X-ray Flares in GX 339-4 (06 Oct 2017)
NICER observed the black hole binary GX339-4 which is currently in outburst. The average hard color (4-12 / 2-4 keV) is near 0.5 or higher, which is harder than the value for Crab (0.25). These results are consistent with the report that GX339-4 is in a faint black hole hard state (Gandhi et al., Atel 10820).
- NICER First ATEL: The Hard X-ray transient MAXI J1535-571 (22 Sep 2017)
NICER has observed the hard X-ray transient MAXI J1535-571 several times from 2017 September 9 through September 20. The source had a NICER count rate ranging from 3,200 to 17,000 counts per second over this interval. NICER detects a set of low-frequency QPOs in a 1:2 frequency ratio, while the time-averaged spectrum shows broadened iron emission and puts constraints on the black hole spin parameter and the inclination of the accretion disk.
