Search for Outbursts in the Narrow 511-keV Line from Compact Sources Based on INTEGRAL Data
S. Tsygankov, E. Churazov
We present the results of a systematic search for outbursts in the narrow positron annihilation line on various time scales (5x10^4 - 10^6 s) based on the SPI/INTEGRAL data obtaine…
X-ray pulsars through the eyes of INTEGRAL
A. Lutovinov, S. Tsygankov
Recent results of the spectral and timing analysis of X-ray pulsars in hard X-rays with the INTEGRAL observatory are reviewed. The evolution of the cyclotron line energy with the s…
4U 0115+63 from RXTE and INTEGRAL Data: Pulse Profile and Cyclotron Line Energy
S. S. Tsygankov, A. A. Lutovinov, E. M. Churazov +1
We analyze the observations of the transient X-ray pulsar 4U 0115+63 with the RXTE and INTEGRAL observatories in a wide X-ray (3-100 keV) energy band during its intense outbursts i…
V0332+53 in the outburst of 2004--2005: luminosity dependence of the cyclotron line and pulse profile
S. S. Tsygankov, A. A. Lutovinov, E. M. Churazov +1
We present results of observations of the transient X-ray pulsar V0332+53 performed during a very powerful outburst in Dec, 2004 -- Feb, 2005 with the INTEGRAL and RXTE observatori…
