俄羅斯未來太空探索任務


Lecture:- The Future Space Exploration Missions of Russia

Currently Russia together with the European Space Agency, is working on the EXOMARS program which is devoted to the search for extinct (or even present) primitive life on Mars. This activity was motivated both by earlier findings of a significant amount of subsurface water in certain Martian regions and the recent discovery of the methane eruptions to the Martian atmosphere. The Russian Lunar program includes several landers (LUNA-25, LUNA-27 and LUNA-28) to explore the south polar regions of the Moon with their permafrost deposits, and one orbiter (LUNA-26) to investigate space plasma in the Lunar vicinity. The main scientific tasks of the Lunar program will be the study of mineralogical, chemical, elemental and isotopic content of the regolith and search for volatiles in the regolith of the polar areas; investigation plasma, neutral and dust exosphere and interaction of the space environment with Lunar surface at the poles. The inner structure of the Moon will be also studied by seismic, radio and laser ranging methods.

The KMOS Redshift One Spectroscopic Survey


Seminar:- KROSS – The KMOS Redshift One Spectroscopic Survey

The speaker will present results from the KMOS Redshift One Spectroscopic Survey (KROSS). Using the K-band Multi-object Spectrograph (KMOS) at the Very Large Telescope (VLT), KROSS has gathered integral-field data for ~800 star-forming galaxies at a redshift z~1, when the universe was roughly half its current age and forming the bulk of its stars. KROSS aims to study the spatially-resolved dynamics, star formation properties and metallicities of those middle-aged galaxies. First, the speaker will quantify the dynamical state of the galaxies, thus constraining their likely mass growth mechanisms (e.g. mergers versus secular evolution), painting a picture of galaxies that are both gas-rich and highly turbulent. Second, he will describe the properties of the galaxies departing from the star formation main sequence, revealing that star formation in highly star-forming galaxies is also more concentrated and arises from lower metallicity gas. Third, he will present the observed and baryonic Tully-Fisher (luminosity – rotation velocity) relation, thus constraining the mass-to-light ratios and luminous+dark masses of the galaxies. Last, by degrading and analogously analysing integral-field data of hundreds of local galaxies from the Sydney-AAO Multi-object Integral-field Spectrograph (SAMI) survey, the speaker will derive a comparison Tully-Fisher relation at z=0, thus constraining the luminous+dark mass growth of disk galaxies over the last 7 billions years. This unique comparison also highlights that the systematic effects associated with sample selection and analysis methods are as large as the effects expected from cosmological evolution, and thus that most other results can safely be ignored.

56年前今日美國甘迺迪總統宣佈十年內將太空人送上月球


1961年5月25日,美國總統約翰·甘迺迪在美國國會聯席會議上宣佈支持將太空人送上月球的太陽神計劃,並且計劃在10年內達成目標。

甘迺迪發表的演講如下:

……我相信這個民族能夠齊聚一心全力以赴達成這個目標,即在1970年以前,人類將乘坐太空船登陸月球並且安全返回。沒有任何一個太空項目能夠超越它對人類的影響,超越它對宇宙遠程空間探索的重大作用,也沒有一個太空項目開發如此困難而且花費如此昂貴……

三維觀測星系中分子氣體 – 從廣域動力學到超大質量黑洞


Seminar:- 3D Observations of Molecular Gas in Galaxies – From Global Dynamics to Supermassive Black Holes

The speaker will first briefly review the molecular gas content of early-type galaxies. He will show not only that they unexpectedly harbour much cold gas, but also that it is the best tracer of the circular velocity, thus allowing accurate spatially-resolved dynamical mass measurements in galaxies across the Hubble sequence. Second, the speaker will explore the use of molecular gas for studies of the Tully-Fisher (luminosity-rotational velocity) relation of galaxies to high redshifts. He will highlight the work done to establish local (z=0) benchmarks and will discuss the challenges posed by systematic effects when comparing nearby and distant galaxies. Third, he will demonstrate that CO can be used to easily and accurately measure the mass of the supermassive black holes lurking at galaxy centres. He will discuss substantial ongoing efforts to do this and present many spectacular new ALMA measurements, that open the way to literally hundreds of measurements across the Hubble sequence with a unique method. The speaker will also hint at how the same data allow to study the spatially-resolved properties of giant molecular cloud populations in non-local galaxies for the first time, providing a new tool to understand and contrast the star formation efficiency of galaxies on cloud scale.
