近期,《自然》和《自然·天文》同步发表2篇文章,报告了国际天文学家团队使用甚长基线干涉测量(VLBI)方法观测研究大熊座快速射电暴(FRB)的结果。中国科学院新疆天文台南山26米射电望远镜作为欧洲VLBI网成员,全程参加此项目观测,贡献了大量观测时间,助力揭示FRB起源。
明安图射电频谱日像仪是新一代太阳专用射电成像望远镜,超宽带双圆极化接收馈源是其关键技术之一.轴比是反映双圆极化馈源性能的重要指标,单天线测量轴比的传统方法需要标准天线辅助,本文采用基于相关测量干涉阵馈源轴比的方法,针对MUSER天线数目多,且为户外环境,根据天文观测的需求须经常测试天线的性能的特点,简化了干涉阵望远镜测量轴比的过程,且能够高效的得到准确的测量结果.文中对该方法的测量过程做了详细的说...
Here I describe recent studies of objects with molecular hydrogen emission that is strong relative to other spectral lines. Large telescopes and fast spectrometers have made the 2 {\mu}m window access...
We report the detection, with the CANGAROO-III imaging atmospheric Cherenkov telescope array, of a very high energy gamma-ray signal from the unidentified gamma-ray source HESS J1614-518, which was di...
We provide new measurements of wavenumbers and line identifications of 10 100 UI and UII near-infrared (NIR) emission lines between 2500 cm-1 and 12 000 cm-1 (4000 nm to 850 nm) using archival FTS spe...
We propose a novel method to directly determine dark matter induced electron/positron spectrum at the source from experimental measurements at the earth, without reference to specific particle physics...
We present a one-port calibration technique for characterization of beam waveguide components with a vector network analyzer. This technique involves using a set of known delays to separate the respon...
RXJ1856 and RXJ0720 are the only young isolated radio-quiet neutron stars (NSs) for which trigonometric parallaxes were measured. Due to detection of their thermal emission in X-rays they are importan...
Astronomical Observations of Galactic Radiosources with ESCORT:an small radiotelescope。
The dust in molecular clouds reliably traces the molecular gas within. We used this assumption to get an estimate of the dense cores size and mass in L1217/L1219 by deriving the total optical extinc...
