Bizarre emitter

X-ray astronomers have reported a
bizarre X-ray emitter in the direction of our galactic centre. C Kouveliotou and colleagues have seen this
object in the intensity records of the
large area detectors of the Burst and
Transient Source Experiment on the
orbiting Compton Gamma Ray
Observatory. The odd thing about
this source is that it combines regular oscillating emissions with erratic
flashes. The known X-ray sources
usually pulse regularly or give out
bursts erratically. The acceptable
theory of these two kinds of sources
assumes that the radiation is emitted when material falls into a superdense neutron star.
