银道面天鹅座区域的VERITAS巡天

The VERITAS Survey of the Cygnus Region of the Galactic Plane

Amanda Weinstein

摘要:

银河平面的天鹅座区域包含许多已知的超新星遗迹,超新星,X射线和GeV伽马射线发射体,使其成为北半球甚高能量(VHE)伽马射线调查的主要候选者。VERITAS天文台是一个由四个大气切伦科夫望远镜组成的阵列,位于Mt.美国亚利桑那州南部的霍普金斯大学对银河经度67至82度以及银河纬度-1至4度之间的天鹅座地区进行了广泛的调查。该调查包括超过140小时的观测,在能量超过200 GeV时,平均VHE通量灵敏度超过蟹状星云的4%。在这里,我们报告了这项调查的初步结果。

英文摘要:

The Cygnus region of the Galactic plane contains many known supernova remnants, pulsars, X-ray and GeV gamma-ray emitters which make it a prime candidate for a Very High Energy (VHE) gamma-ray survey in the Northern Hemisphere. The VERITAS observatory, an array of four atmospheric Cherenkov telescopes located at the base of Mt. Hopkins in southern Arizona, USA, has carried out an extensive survey of the Cygnus region between 67 and 82 degrees in galactic longitude and between -1 and 4 degrees in galactic latitude. The survey, comprising more than 140 hours of observations, reaches an average VHE flux sensitivity of better than 4% of the Crab Nebula at energies above 200 GeV. Here we report on the preliminary results from this survey.
