摘要

VERITAS位于亚利桑那州南部,是最灵敏的天体物理高能探测器(VHE;E>100 GeV)伽马射线,自2007年4月开始运行。我们重点介绍了VERITAS最近的一些观察结果。其中包括对伽玛射线双星HESS J0632+057和LS I +61°303的长期观测,对银河系中心区域的观测,以及对超新星遗迹Cas a的观测。我们讨论了十年来对blazar 1ES 1215+303的多波长观测结果,对M87星系的EHT 2017运动,VHE中3C 264的发现,以及对三个耀斑类星体的观测。简要强调了间接暗物质搜索和机会目标(ToO)观测。ToO观测允许对多信使警报和天体物理瞬变进行快速跟踪。

VERITAS highlights of observations and results
Located in southern Arizona, VERITAS is amongst the most sensitive detectors for astrophysical very high energy (VHE; E>100 GeV) gamma rays and has been operational since April 2007. We highlight some recent results from VERITAS observations. These include the long-term observations of the gamma-ray binaries HESS J0632+057 and LS I +61° 303, the observations of the Galactic Center region, and of the supernova remnant Cas A. We discuss the results from a decade of multi-wavelength observations of the blazar 1ES 1215+303, the EHT 2017 campaign on the M87 galaxy, the discovery of 3C 264 in VHE, and the observation of three flaring quasars. Brief highlights of the indirect dark matter searches and targets-of-opportunity (ToO) observations are also discussed. The ToO observations allow for rapid follow-up of multi-messenger alerts and astrophysical transients.
