New continuum and polarization observations of the Cygnus Loop with FAST I. Data processing and verification
RESEARCH IN ASTRONOMY AND ASTROPHYSICS(2021)
摘要
We report on the continuum and polarization observations of the Cygnus Loop supernova remnant (SNR) conducted by the Five-hundred-meter Aperture Spherical radio Telescope (FAST). FAST observations provide high angular resolution and high sensitivity images of the SNR, which will help to disentangle its nature. We obtained Stokes I, Q and U maps over the frequency range of 1.03 - 1.46 GHz split into channels of 7.63 kHz. The original angular resolution is in the range of similar to 3'-similar to 3'.8 更多
