加拿大银道面巡天自转测量的再探讨：外星系盘的磁场
Revisiting Rotation Measures from the Canadian Galactic Plane Survey: the Magnetic Field in the Disk of the Outer Galaxy
摘要：
法拉第旋转提供了星际介质中磁场的有价值的示踪剂;法拉第旋转测量的目录为研究银河系磁场提供了关键的观测结果。我们提出了一个新的星表的旋转措施，来自加拿大银河平面调查，涵盖了大范围的银河平面跨越52度< l < 192度，-3度< b < 5度，以及南北纬度扩展约l ~ 105度。我们已经推导出旋转措施2234源（其中4个是已知的卫星），其中75%没有以前的测量，在一个面积约1300平方度。这些新的旋转测量将银河平面这一区域的测量密度增加了两倍。
英文摘要：
Faraday rotation provides a valuable tracer of magnetic fields in the interstellar medium; catalogs of Faraday rotation measures provide key observations for studies of the Galactic magnetic field. We present a new catalog of rotation measures derived from the Canadian Galactic Plane Survey, covering a large region of the Galactic plane spanning 52 deg < l < 192 deg, -3 deg < b < 5 deg, along with northern and southern latitude extensions around l ~ 105 deg. We have derived rotation measures for 2234 sources (4 of which are known pulsars), 75% of which have no previous measurements, over an area of approximately 1300 square degrees. These new rotation measures increase the measurement density for this region of the Galactic plane by a factor of two.
