天鹅座区域的VERITAS观测

VERITAS observations of the Cygnus Region

Ralph Bird

摘要:

天鹅座区域是气体和恒星形成最丰富的区域之一,也是北天弥漫GeV辐射最明亮的区域。VERITAS在天鹅座区域方向进行了深度观测(大约300小时),达到了蟹状星云流量百分之几的平均灵敏度。我们提出了这些观测的结果和超过7年的费米-LAT数据超过1 GeV的分析。除了在该地区寻找新的来源,我们提出了更新的光谱和形态的已知TeV的伽马射线源和它们的关系与GeV的发射从该地区的研究。这些结果进行了讨论,在其多波长的背景下,包括最近出版的HAWC天文台伽玛射线目录。还与H.E.S.S.银道面巡天

英文摘要:

The Cygnus region of the galaxy is one of the richest regions of gas and star formation and is the brightest region of diffuse GeV emission in the northern sky. VERITAS has conducted deep observations (approximately 300 hours) in the direction of Cygnus region, reaching an average sensitivity of a few percent of the Crab nebula flux. We present the results of these observations and an analysis of over seven years of Fermi-LAT data above 1 GeV. In addition to a search for new sources in the region, we present updated spectra and morphologies of the known TeV gamma-ray sources and a study of their relationship with the GeV emission from the region. These results are discussed in their multiwavelength context including the recently published HAWC observatory gamma-ray catalog. A comparison is also made to the H.E.S.S. galactic plane survey.
