Abstract

This review arose from the European Radio Astronomy Technical Forum (ERATec) meeting held in Firenze, October 2015, and aims to highlight the breadth and depth of the high-impact science that will be aided and assisted by the use of simultaneous mm-wavelength receivers.

Recent results and opportunities are presented and discussed from the fields of: continuum VLBI (observations of weak sources, astrometry, observations of AGN cores in spectral index and Faraday rotation), spectral line VLBI (observations of evolved stars and massive star-forming regions) and time domain observations of the flux variations arising in the compact jets of X-ray binaries.

Our survey brings together a large range of important science applications, which will greatly benefit from simultaneous observing at mm-wavelengths. Such facilities are essential to allow these applications to become more efficient, more sensitive and more scientifically robust. In some cases without simultaneous receivers the science goals are simply unachievable. Similar benefits would exist in many other high frequency astronomical fields of research.

射电天文学中同时使用毫米波长接收器的科学案例

这篇综述源于2015年10月在佛罗伦萨举行的欧洲射电天文学技术论坛(ERATec)会议，旨在强调高影响力科学的广度和深度，这将得益于同时使用毫米波长接收器。从连续体VLBI(弱源观测、天体测量、AGN核心光谱指数和法拉第旋转观测)、谱线VLBI(演化恒星和大质量恒星形成区域观测)和x射线双星致密射流中通量变化的时域观测等领域介绍和讨论了最近的结果和机会。我们的调查汇集了大量重要的科学应用，这将极大地受益于同时观测毫米波长。这些设施对于提高这些应用的效率、灵敏度和科学可靠性至关重要。在某些情况下，如果没有同时的接受者，科学目标根本无法实现。类似的好处也存在于许多其他高频天文学领域的研究中。
