NuSTAR detection of a cyclotron line in the supergiant fast X-ray transient IGR J17544-2619

We present NuSTAR spectral and timing studies of the supergiant fast X-ray transient (SFXT) IGR J17544−2619. The spectrum is well described by an ~1 keV blackbody and a hard continuum component, as expected from an accreting X-ray pulsar. We detect a cyclotron line at 17 keV, confirming that the com...
