The 4MOST consortium is currently halfway through a Conceptual Design study for ESO with the aim to develop a wide-field (>3 square degree, goal >5 square degree), high-multiplex (>1500 fibres, goal 3000 fibres) spectroscopic survey facility for an ESO 4m-class telescope (VISTA). 4MOST will run permanently on the telescope to perform a 5 year public survey yielding more than 20 million spectra at resolution R~5000 (λ=390-1000 nm) and more than 2 million spectra at R~20,000 (395-456.5 nm & 587-673 nm). The 4MOST design is especially intended to complement three key all-sky, space-based observatories of prime European interest: Gaia, eROSITA and Euclid. Initial design and performance estimates for the wide-field corrector concepts are presented. We consider two fibre positioner concepts, a well-known Phi-Theta system and a new R-Theta concept with a large patrol area. The spectrographs are fixed configuration two-arm spectrographs, with dedicated spectrographs for the high- and low-resolution. A full facility simulator is being developed to guide trade-off decisions regarding the optimal field-of-view, number of fibres needed, and the relative fraction of high-to-low resolution fibres. Mock catalogues with template spectra from seven Design Reference Surveys are simulated to verify the science requirements of 4MOST. The 4MOST consortium aims to deliver the full 4MOST facility by the end of 2018 and start delivering high-level data products for both consortium and ESO community targets a year later with yearly increments.
Spectropolarimetry with the Giant Metrewave Radio Telescope at 610 MHz: a case study of two Southern Compact Group fields
我们目前610兆赫的光谱偏振图像从巨型米波射电望远镜(GMRT)。我们详细讨论了GMRT的全偏振模式的属性,并提供了仪器的偏振性能的技术表征。我们表明,该望远镜可用于宽视场分光偏振。旋转测量合成的应用导致在法拉第空间中的几十微焦的水平的灵敏度。作为该仪器的能力的演示,我们提出了两个南方契约组-鹤四重奏和USCG S 063的意见。观测结果与其他无线电和红外数据进行了比较,以限制组成员的光谱指数,偏振分数和法拉第深度。无线电连续辐射是从天鹤座四重奏中的所有四个星系和USCG S 063中的一个星系中检测到的。线性偏振是从NGC 7552的环核星暴环,NGC 7582的活动核和三个扩展的射电星系在天鹤座四重奏场的背景中检测到的。这些背景源允许分类FR-I和X形射电星系。没有证据表明,在任何星系群与群内介质的相互作用。
Special spectroscopic observations and rare solar events collected in the first half of the twentieth century with Meudon spectroheliograph
1892年,亨利·德斯兰德雷斯在巴黎天文台开始了太阳大气层的成像光谱学。他发明了,同时与乔治黑尔在肯伍德(美国),但相当独立,spectroheliographer设计的单色图像的太阳。Deslandres开发了两种光谱仪:“spectroh {é}liographe des formes”,即窄带仪器,用于显示色球层结构(如太阳的暗条、暗区、谱斑和活动区);以及“spectroh {é}liographe des vitesses”,即“截面”分光仪,用以记录太阳截面的谱线轮廓,以测量动态特征的多普勒频移。1898年,Deslandres带着他的仪器搬到了Meudon,并改进了光谱和空间分辨率,导致了1908年与Lucien d 'Azambuja一起开发的大型四重分光仪。CaII K的系统观测始于这一天,随后在1909年由H $α$用两台专用的3米太阳分光仪进行。观测服务是由d 'Azambuja谁也密集使用大型7米spectroheliographer为他的研究和论文(1930年)。本文总结了50年的研究先生和夫人d 'Azambuja,谁探索了各种光球和色球线,执行特殊的spectroheliograms与高色散7米仪器。在二十世纪上半叶,他们还密集地观测了暗条和双折射(1948年出版的回忆录),并用两台3米太阳分光仪记录了罕见的太阳活动事件。
