Short-Term Variability of X-rays from Accreting Neutron Star Vela X-1: II. Monte-Carlo Modeling
Hirokazu Odaka, Dmitry Khangulyan, Yasuyuki T. Tanaka +3
We develop a Monte Carlo Comptonization model for the X-ray spectrum of accretion-powered pulsars. Simple, spherical, thermal Comptonization models give harder spectra for higher o…
Simple analytical approximations for treatment of inverse Compton scattering of relativistic electrons in the black-body radiation field
Dmitry Khangulyan, Felix A. Aharonian, Stanislav R. Kelner
The inverse Compton (IC) scattering of relativistic electrons is one of the major gamma-ray production mechanisms in different environments. Often the target photons for the IC sca…
On the Jitter Radiation
Stanislav R. Kelner, Felix A. Aharonian, Dmitry Khangulyan
In a small scale turbulent medium, when the nonrelativistic Larmor radius exceeds the correlation length of the magnetic field, the magnetic bremsstrahlung…
Star-Jet Interactions and Gamma-Ray Outbursts from 3C454.3
D. V. Khangulyan, M. V. Barkov, V. Bosch-Ramon +2
We propose a model to explain the ultra-bright GeV gamma-ray flares observed from the blazar 3C454.3. The model is based on the concept of a relativistic jet interacting with compa…
Short-Term Variability of X-rays from Accreting Neutron Star Vela X-1: I. Suzaku Observations
Hirokazu Odaka, Dmitry Khangulyan, Yasuyuki T. Tanaka +3
We have analyzed the time variability of the wide-band X-ray spectrum of Vela X-1, the brightest wind-fed accreting neutron star, on a short timescale of 2 ks by using {\it Suzaku}…
