Gamma-rays are the highest energy form of electromagnetic radiation. Observations of astrophysical gamma-rays serve as probes of physical conditions and processes in the most extreme environments throughout the Universe, and can be used to test fundamental physics. The Very Energetic Radiation Imaging Telescope Array System (VERITAS), located in southern Arizona, is a ground-based observatory designed to study high energy gamma-rays. VERITAS has unique capabilities, providing high sensitivity pointed observations of both galactic and extragalactic sources. This award supports scientists at Barnard College to carry out research with VERITAS. The group will participate in both technical operations in support of the observatory and scientific investigations with a focus on studying emission from active galaxies, pulsar wind nebula, and gamma-ray bursts. The Barnard College group is heavily engaged in education and outreach efforts. They involve undergraduate students in astrophysics research with an emphasis on broadening the participation of women. They are also involved in outreach efforts to high-school students in the New York City area. VERITAS has embarked upon a broad program of Galactic and extragalactic source observations, as well as studies of signatures for new physics such as dark matter. With this award the Barnard College group will participate in VERITAS observing and calibration campaigns and work on code development for improvements to VERITAS analysis techniques. Their scientific program includes searching for high energy emission and variability in blazars, using pulsar wind nebula and multi-messenger approaches to investigate the origin of cosmic rays, and studying gamma-ray bursts.

伽马射线是电磁辐射的最高能量形式。 天体物理伽马射线的观察是整个宇宙中最极端环境中物理条件和过程的探针，可用于测试基本物理学。 位于亚利桑那州南部的非常充满活力的辐射成像望远镜阵列系统（Veritas）是一个基于地面的天文台，旨在研究高能伽马射线。 Veritas具有独特的功能，提供了对银河系和外层面源的高灵敏度观察。 该奖项支持巴纳德学院的科学家与Veritas进行研究。 该小组将参加两项技术操作，以支持观测站和科学研究，重点是研究活跃星系，脉冲星云和伽马射线爆发的发射。 Barnard College Group大量从事教育和外展工作。 他们涉及本科生参加天体物理学研究，重点是扩大妇女的参与。 他们还参与了纽约市高中生的外展工作。 Veritas启动了一项广泛的银河系和乳清外源观察，以及对新物理（例如暗物质）的签名的研究。 通过此奖项，Barnard College Group将参加Veritas观察和校准运动，并从事代码开发工作以改进Veritas分析技术。 他们的科学计划包括使用Pulsar Wind Nebula和多通信的方法来研究宇宙射线的起源，并研究伽马射线爆发。
