伽马射线是能量最高的光子，携带着来自遥远的河外空间的信息，相互作用或信息损失最小。它们带来了关于粒子加速的信息，这些信息在极端的环境中是无法在地球上复制的。伽马射线天体物理学与对撞机的工作是如此互补，以至于粒子物理学家和天体粒子物理学家经常是同一个人。伽马射线仪器，特别是费米伽马射线太空望远镜，在过去十年的重大多信使发现中发挥了关键作用。目前，在推动新技术、规划和建造空间和地面伽马射线设施以及建立以伽马射线为核心的多信使网络方面，存在着极大的兴趣和科学专门知识。因此，令人关切的是，在社区再次聚集在一起进行规划工作之前，由于缺乏支持伽马射线天体物理学的长期规划，大部分基础设施可能会损失。因此，能量从MeV到EeV波段的伽马射线是多波长和多信使研究的核心，从紧凑物体的天体粒子物理学到弥漫大尺度结构的暗物质研究。这些目标和新的发现产生了一波新的伽马射线设施的建议和计划。本文重点介绍了新的和拟议中的伽马射线技术和设施，这些技术和设施都是为了满足测量极端天体物理源的特定需求而设计的，这些极端天体物理源探测了未来十年基础物理学中一些最紧迫的问题。拟议的仪器还将解决最近的Astro2020 Decadal Survey中列出的优先事项，这是天体物理学界的一项补充研究，提供了与Snowmass相关的机会。
Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about particle acceleration in environments so extreme they cannot be reproduced on earth for a closer look. Gamma-ray astrophysics is so complementary with collider work that particle physicists and astroparticle physicists are often one in the same. Gamma-ray instruments, especially the Fermi Gamma-ray Space Telescope, have been pivotal in major multi-messenger discoveries over the past decade. There is presently a great deal of interest and scientific expertise available to push forward new technologies, to plan and build space- and ground-based gamma-ray facilities, and to build multi-messenger networks with gamma rays at their core. It is therefore concerning that before the community comes together for planning exercises again, much of that infrastructure could be lost to a lack of long-term planning for support of gamma-ray astrophysics. Gamma-rays with energies from the MeV to the EeV band are therefore central to multiwavelength and multi-messenger studies to everything from astroparticle physics with compact objects, to dark matter studies with diffuse large scale structure. These goals and new discoveries have generated a wave of new gamma-ray facility proposals and programs. This paper highlights new and proposed gamma-ray technologies and facilities that have each been designed to address specific needs in the measurement of extreme astrophysical sources that probe some of the most pressing questions in fundamental physics for the next decade. The proposed instrumentation would also address the priorities laid out in the recent Astro2020 Decadal Survey, a complementary study by the astrophysics community that provides opportunities also relevant to Snowmass.
