Observation and Simulation of the Variable Gamma-ray Emission from PSR~J2021+4026
C. W. Ng, J. Takata, K. S. Cheng
Pulsars are rapidly spinning and highly magnetized neutron stars, with highly stable rotational period and gradual spin-down over a long timescale due to the loss of radiation. Gli…
Origin of Hydrogen Ionization in the 1 pc Galactic Central Region
D. O. Chernyshov, Gene C. K. Leung, K. S. Cheng +2
We study a possible connection between processes of gamma-ray emission and hydrogen ionization in a few pc of central region around Sgr A*. Previous investigations showed there is…
Multi-wavelength Emission from the Fermi Bubble I. Stochastic acceleration from Background Plasma
K. S. Cheng, D. O. Chernyshov, V. A. Dogiel +1
We analyse processes of electron acceleration in the Fermi Bubbles in order to define parameters and restrictions of the models, which are suggested for the origin of these giant r…
Origin of Nonthermal Emission from the Fermi Bubbles and Mechanisms of Particle Acceleration There
V. A. Dogiel, K. -S. Cheng, D. O. Chernyshov +1
We analyse processes of particle acceleration in the Fermi Bubbles. The goal of our investigations is to obtain restrictions for acceleration mechanisms. Our analysis of the three…
Radiation Mechanism of the Soft Gamma-ray Pulsar PSR B1509-58
Y. Wang, J. Takata, K. S. Cheng
The outer gap model is used here to explain the spectrum and the energy dependent light curves of the X-ray and soft gamma-ray radiations of the spin-down powered pulsar PSR B1509-…
The Fermi Bubble as a Source of Cosmic Rays in the Energy Range > 10E15 eV
K. S. Cheng, D. O. Chernyshov, V. A. Dogiel +3
The {\it Fermi} Large Area Telescope has recently discovered two giant gamma-ray bubbles which extend north and south of the Galactic center with diameters and heights of the order…
