Identification of radio and gamma-ray pulsars in X-rays using data from the SRG/eROSITA all-sky survey
Yu. A. Shibanov, A. V. Karpova, D. A. Zyuzin +1
Using the data from the all-sky survey in soft X-rays performed by the eROSITA telescope onboard the Spectrum-Roentgen-Gamma observatory we identified known radio and -ray puls…
MASTER OT J072007.30+451611.6: A Polar with Strong Optical Variability and Suppressed He II Emission
A. V. Bobakov, S. V. Zharikov, A. V. Karpova +8
The transient optical source MASTER OT J072007.30+451611.6 has been recently discovered and proposed as a peculiar polar with an unusually high amplitude of the orbital brightness…
Is the Fermi source 4FGL J1824.2+1231 a transitional millisecond pulsar?
D. A. Zyuzin, A. V. Karpova, A. Yu. Kirichenko +9
Transitional millisecond pulsars (tMSPs) in tight binary systems represent an important evolutionary link between low-mass X-ray binaries and radio millisecond pulsars. To date, on…
The middle-aged pulsar PSR J1741-2054 and its bow-shock nebula in far ultraviolet
Vadim Abramkin, George G. Pavlov, Yuriy Shibanov +2
Context. The nearby middle-aged gamma-ray pulsar J1741-2054 and its pulsar wind nebula (PWN) have been studied in X-rays, and its bow-shock nebula (BSN) has been investigated in th…
SRGe J194401.8+284452 -- an X-ray Cataclysmic Variable in the Field of the Gamma-Ray Source 4FGL J1943.9+2841
A. I. Kolbin, A. V. Karpova, M. V. Suslikov +19
SRGe J194401.8+284452 is the brightest point-like X-ray object within the position uncertainty ellipse of an unidentified -ray source 4FGL J1943.9+2841. We performed multi-wave…
Two black widow pulsars in the optical and X-rays
A. V. Bobakov, A. Yu. Kirichenko, S. V. Zharikov +5
Context. Two millisecond pulsars, PSR J15132550 and PSR J20171614, with spin periods of about 2.1 and 2.3 ms were recently discovered in the radio and -rays and classifie…
