X-ray and Gamma-ray Emissions from Different Evolutionary Stage of Rotation Powered Millisecond Pulsars
J. Takata, K. S. Cheng, R. E. Taam
The -LAT has revealed that rotation powered millisecond pulsars (MSPs) are a major contributor to the Galactic -ray source population. Such pulsars may also be important…
Gamma-ray properties of globular clusters and the "fundamental planes"
P. Tam, A. Kong, C. Y. Hui +1
We report on the discovery of gamma-ray emission from several globular clusters (GCs), including Terzan 5, the second known gamma-ray GCs. By now, more than a dozen GCs are known t…
Population study for -ray emitting Millisecond Pulsars and unidentified sources
J. Takata, Y. Wang, K. S. Cheng
The -LAT has revealed that rotation powered millisecond pulsars (MSPs) are a major contributor to the Galactic -ray source population. We discuss the -ray emission pro…
Three-dimensional Two-Layer Outer Gap Model: the Third Peak of Vela Pulsar
Y. Wang, J Takata, K. S. Cheng
We extend the two-dimensional two-layer outer gap model to a three-dimensional geometry and use it to study the high-energy emission of the Vela pulsar. We apply this three-dimensi…
Discovery of gamma-ray emission from the supernova remnant Kes 17 with Fermi Large Area Telescope
J. H. K. Wu, E. M. H. Wu, C. Y. Hui +4
We report the discovery of GeV emission at the position of supernova remnant Kes 17 by using the data from the Large Area Telescope on board the Fermi Gamma-ray Space Telescope. Ke…
Population study for gamma-ray pulsars: (III) Radiation characteristics and viewing geometry
J. Takata, Y. Wang, K. S. Cheng
We have performed a Monte-Calro simulation for Galactic population of pulsars and for the -ray observations. We apply outer gap model for the -ray emission process, and study…
Discovery of GeV gamma-ray emission from PSR B1259-63/LS 2883
P. H. Thomas Tam, Regina H. H. Huang, Jumpei Takata +3
The binary system PSR B1259-63/LS 2883 consists of a 47.8 ms radio pulsar that orbits the companion Be star with a period of 3.4 years in a highly eccentric orbit. The system is we…
Three-dimensional Two-Layer Outer Gap Model: Fermi Energy Dependent Light Curves of the Vela Pulsar
Y. Wang, J. Takata, K. S. Cheng
We extend the two-dimensional two-layer outer gap model to a three-dimensional geometry and use it to study the high-energy emission of the Vela pulsar. In this model, the outer ga…
Population study for gamma-ray pulsars; II Millisecond pulsars
J. Takata, Y. Wang, K. S. Cheng
The population of -ray emitting millisecond pulsars (MSPs) is studied by using Monte-Carlo techniques. We simulate the Galactic distributions of the MSPs, and apply the outer ga…
The luminosity function of Swift long gamma-ray bursts
Xiao-Feng Cao, Yun-Wei Yu, K. S. Cheng +1
The accumulation of {\it Swift} observed gamma-ray bursts (GRBs) gradually makes it possible to directly derive a GRB luminosity function (LF) from observational luminosity distrib…
