Intermittent millisecond x-ray pulsations from the neutron star x-ray transient SAX J1748.9-2021 in the globular cluster NGC 6440
We report on intermittent X-ray pulsations with a frequency of 442.36 Hz from the neutron-star X-ray binary SAX J1748.9-2021 in the globular cluster NGC 6440. The pulsations were seen during both 2001 and 2005 outbursts of the source, but only intermittently, appearing and disappearing on timescales...
