Discovery of a pulse-phase-transient cyclotron line in the X-ray pulsar Swift J1808.4-1754 and identification of an optical companion
Alexander Salganik, Sergey S. Tsygankov, Alexander A. Lutovinov +3
In this work, the temporal and spectral properties of the poorly studied X-ray pulsar Swift J1808.41754 were investigated in the 0.8-79 keV energy range based on the data from t…
On the nature of the X-ray pulsar XTE J1859+083 and its broadband properties
Alexander Salganik, Sergey S. Tsygankov, Anlaug A. Djupvik +5
This work is devoted to the study of the broadband 0.8-79 keV spectral and timing properties of the poorly studied X-ray pulsar XTE J1859+083 during its 2015 outburst based on the…
X-ray pulsar XTE J1858+034: discovery of the cyclotron line and the revised optical identification
Sergey S. Tsygankov, Alexander A. Lutovinov, Sergey V. Molkov +7
We present results of a detailed investigation of the poorly studied X-ray pulsar XTE J1858+034 based on the data obtained with the NuSTAR observatory during the outburst of the so…
Detection of a gamma-ray flare from the high-redshift blazar DA 193
Vaidehi S. Paliya, M. Ajello, R. Ojha +10
High-redshift () blazars are the most powerful members of the blazar family. Yet, only a handful of them have both X-ray and -ray detection, thereby making it difficult to…
