MGRO J2019 +37复合体的无线电和近红外小型测量
A radio and near-infrared mini-survey of the MGRO J2019+37 complex
摘要：
MGRO J2019+37是一个未经确认的极高能量伽马射线源，最初由MILAGRO合作报告为天鹅座地区最亮的TeV源。尽管MILAGRO的角分辨率很差，但这个物体似乎最有可能是一个扩展源，或者是一个点状TeV源的叠加。为了有助于理解这个奇特的物体，我们已经用印度浦那的巨型米波射电望远镜（GMRT）在610 MHz频率下将其镶嵌起来，覆盖了大约6平方度的视场，直到典型的均方根噪声为零点几mJy。我们还观察了中央平方度的马赛克在近红外KS波段使用3.5米望远镜和OMEGA2000相机在Calar Alto天文台（西班牙）。我们在这里提出的第一个帐户，我们的观察和结果，连同一个射电和红外源目录的互相关性，以及与该地区的可用X射线观测的相关性。
英文摘要：
MGRO J2019+37 is an unidentified source of very high energy gamma-rays originally reported by the MILAGRO collaboration as the brightest TeV source in the Cygnus region. Despite the poor angular resolution of MILAGRO, this object seems to be most likely an extended source or, alternatively, a superposition of point-like TeV sources. In order to contribute to the understanding of this peculiar object, we have mosaiced it with the Giant Metrewave Radio Telescope (GMRT) in Pune, India, at the 610 MHz frequency covering a field of view of about 6 square degrees down to a typical rms noise of a few tenths of mJy. We also observed the central square degree of this mosaic in the near infrared Ks-band using the 3.5 m telescope and the OMEGA2000 camera at the Calar Alto observatory (Spain). We present here a first account of our observations and results, together with a preliminar cross correlation of the radio and infrared source catalog as well as a correlation with the available X-ray observations of the region.
