Large-Scale Anisotropy of EGRET Gamma Ray Sources
Luis Anchordoqui, Thomas McCauley, Thomas Paul +2
In the course of its operation, the EGRET experiment detected high-energy gamma ray sources at energies above 100 MeV over the whole sky. In this communication, we search for large…
On the Observational Status of Ultrahigh Energy Cosmic Rays and their Possible Origin in Starburst-Like Galaxies
Diego F. Torres, Luis A. Anchordoqui
This paper presents a brief review of the current status of ultrahigh energy cosmic ray observations and discusses nearby starburst-like galaxies as their possible origin.
On the nature of the unidentified MeV gamma-ray source GRO 1411-64
Gustavo E. Romero, Mariana Orellana, Diego F. Torres
A recent analysis of COMPTEL data has revealed the existence of an unidentified and variable gamma-ray source, designated GRO J1411-64, at MeV energies in the galactic plane (Zhang…
Unidentified Gamma-Ray Sources and Microquasars
G. E. Romero, I. A Grenier, M. M. Kaufman Bernado +2
Some phenomenological properties of the unidentified EGRET detections suggest that there are two distinct groups of galactic gamma-ray sources that might be associated with compact…
