Discovery of a retrogradely rotating neutron star in the X-ray pulsar GX 3012
Juhani Mönkkönen, Victor Doroshenko, Sergey S. Tsygankov +3
We report on the analysis of the spin evolution of a slow X-ray pulsar GX 3012 along the orbit using long-term monitoring by Fermi/GBM. Based on the observationally confirmed ac…
NuSTAR observations of the wind-fed X-ray pulsar GX 301--2 during an unusual spin-up event
Armin Nabizadeh, Juhani Mönkkönen, Sergey S. Tsygankov +3
We report on \textit{NuSTAR} observations of the well-known wind-accreting X-ray pulsar \source\ during a strong spin-up episode that took place in January-March 2019. A high lumin…
Properties of the transient X-ray pulsar Swift J1816.7--1613 and its optical companion
Armin Nabizadeh, Sergey S. Tsygankov, Dmitrij I. Karasev +4
We present results of investigation of the poorly studied X-ray pulsar Swift J1816.7--1613 during its transition from the type I outburst to the quiescent state. Our studies are ba…
