标题： A Multi-Wavelength Investigation of the Unidentified Gamma-Ray Source HESS J1708-410

摘要： 我们报告了关于未知银河平面源HESS J1708-410的近期XMM-Newton观测数据、存档的射电连续谱和CO数据以及SED建模。未观测到显著的扩展X射线发射，在TeV发射区域的2-4 keV范围内，我们对该区域的X射线上限为3.2 x 10{-13} erg cm{-2} s{-1}。使用Molonglo银河平面巡天数据，该源在843 MHz处的上限为0.27 Jy，而帕克斯南部银河平面巡天则给出了2.4 GHz的上限为0.4 Jy。此区域的12CO (J 1->0) 数据表明HESS J1708-410的距离可能为3 kpc。H.E.S.S.探测和通量上限的SED建模为该源周围的辐射机制、磁场、注入光谱以及周边介质提供了有用的限制。 显示英文摘要

摘要： We report on recent XMM-Newton observations, archival radio continuum and CO data, and SED modeling of the unidentified Galactic plane source HESS J1708-410. No significant extended X-ray emission is observed, and we place an upper limit of 3.2 x 10{-13} erg cm{-2} s{-1} in the 2-4 keV range for the region of TeV emission. Molonglo Galactic Plane Survey data is used to place an upper limit of 0.27 Jy at 843 MHz for the source, with a 2.4 GHz limit of 0.4 Jy from the Parkes survey of the southern Galactic plane. 12CO (J 1->0) data of this region indicates a plausible distance of 3 kpc for HESS J1708-410. SED modeling of both the H.E.S.S. detection and flux upper limits offer useful constraints on the emission mechanisms, magnetic field, injection spectrum, and ambient medium surrounding this source.
