2Optical observations of LIGO source GW 170817 by the Antarctic Survey Telescopes at Dome A,Antarctica显示文摘The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light.lei hu xuefeng wu igor andreoni michael c.b.ashley jeff cooke xiangqun cui fujia du zigao dai bozhong gu yi hu haiping lu xiaoyan li zhengyang li ensi liang liangduan liu bin ma zhaohui shang tianrui sun n.b.suntzeff charling tao syed a.uddin lifan wang xiaofeng wang haikun wen di xiao jin xu ji yang shihai yang xiangyan yuan hongyan zhou hui zhang jilin zhou zonghong zhu 2017Science Bulletin2017,62,21:6
3核保的未来显示文摘'新一代核保'的到来可能会比我们想象的更快,原地踏步绝不是明智的选择,止步不前会让保险公司处于被时代抛弃的巨大风险中。曾在佰仕富英国、中国香港及新加坡区域总部担任核保负责人的Jeff Cook先生分享了全球范围内传统核保向新型核保转型的情况,探讨了未来'新一代核保'技术的形态。Jeff Cook 2019上海保险2019,0,2:2

11Detection of a possible superluminous supernova in the Epoch of Reionization显示文摘The Epoch of Reionization(EoR)poses a number of puzzles,including the sufficiency of ionizing radiation,the rapid production of supermassive black holes and the early appearance of abundant metals in larger galaxies.For the first of these,solutions focus on the main sequence evolution of massive stars,but the second and third puzzles involve the terminal phase of stellar evolution,Jeremy Mould Tim Abbott Jeff Cooke Chris Curtin Antonios Katsianis Anton Koekemoer Edoardo Tescari Syed Uddin Lifan Wang Stuart Wyithe 2017Science Bulletin2017,62,10:0
