摘要

康普顿天文台EGRET任务的主要目标之一一直是研究星系和星系外起源的漫射伽马射线发射。任务的前18个月,在初始激活期之后,将致力于全天调查,目标是获得几乎均匀的曝光。相对于早期的SAS - 2和COS - B任务,EGRET仪器的能力有所提高,因此开发了一个新的星系漫射伽马射线发射模型,该模型结合了最近对物质分布的调查,并允许对星系宇宙射线分布的各种假设进行测试。本文对模型计算进行了总结,并与EGRET观测值进行了初步比较。

High energy gamma ray observations and the coupling between galactic cosmic rays and matter
One of the primary goals of the EGRET mission on the Compton Observatory has always been the study of the diffuse gamma ray emission of both galactic and extra‐galactic origin. The first 18 months of the mission, following the initial activation period, is being devoted to the all‐sky survey with the goal of obtaining a nearly uniform exposure. In anticipation of the improved capabilities of the EGRET instrument relative to the earlier SAS‐2 and COS‐B missions, a new model of the galactic diffuse gamma ray emission was developed that incorporates recent surveys of the matter distribution and which permits a variety of assumptions regarding galactic cosmic ray distribution to be tested. This paper summarizes the model calculation and gives a preliminary comparison of the model with EGRET observations.
