Population study for gamma-ray pulsars with the outer gap model
J. Takata, Y. Wang, K. S. Cheng
Inspired by increase of population of -ray emitting pulsars by the telescope, we perform a population study for -ray emitting canonical pulsars. We use a Monte-Carlo…
Electron-positron energy deposition rate from neutrino pair annihilation on the rotation axis of neutron and quark stars
Z. Kovacs, K. S. Cheng, T. Harko
We investigate the deposition of energy due to the annihilations of neutrinos and antineutrinos on the rotation axis of rotating neutron and quark stars, respectively. The source o…
Multiwavelength properties of a new Geminga-like pulsar: PSR J2021+4026
L. Trepl, C. Y. Hui, K. S. Cheng +4
In this paper, we report a detailed investigation of the multiwavelength properties of a newly detected gamma-ray pulsar, PSR J2021+4026, in both observational and theoretical aspe…
Gamma-ray spectral properties of mature pulsars: a two-layer model
Y. Wang, J. Takata, K. S. Cheng
We use a simple two-layer outer gap model, whose accelerator consists of a primary region and a screening region, to discuss -ray spectrum of mature pulsars detected by .…
Inflation and late time acceleration in braneworld cosmological models with varying brane tension
K. C. Wong, K. S. Cheng, T. Harko
Braneworld models with variable brane tension introduce a new degree of freedom that allows for evolving gravitational and cosmological constants, the latter being a natural ca…
Outer gap accelerator closed by magnetic pair-creation process
J. Takata, Y. Wang, K. S. Cheng
We discuss outer gap closure mechanism in the trans-field direction with the magnetic pair-creation process near the stellar surface. The gap closure by the magnetic pair-creation…
