| 1 | Optical 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 | 2017 | Science Bulletin2017，62，21： | 6 |

| 3 | A Statistical Analysis on Tidal Triggering of Earthquakes in the Kashi-Wuqia Intersection Area in Xinjiang显示文摘A statistical analysis on earthquake activity in the Kashi-Wuqia intersection area triggered by earth tide is done by Schusters test and the Permutation test on daily and monthly scales. The north-south,east-west component of the tidal force and tidal body stress are chosen as the tidal curve in the daily scale. The results show that most of the earthquakes occurred near the maximum 0° of the three kinds of tidal curves,the predominant tidal phases of the earthquake are- 5. 86°,6. 60° and- 15. 52°,and the frequency of the earthquakes increases with the increase of the tide; with three kinds of tidal curves( the north-south,east-west component of the tidal force and tidal body stress),the p S of Schusters test for all the earthquakes is 10. 52%,2. 40% and 2. 06%,and the p P of the Permutation test is 10. 90%,2. 40% and 2. 06%,and the results of p S and p P based on the east-west component of the tidal force and tidal body stress are below the threshold of 0. 05 that tidal triggering of earthquakes. In the monthly scale,both the p S and p P are very low( close to 0),far below the threshold of 0. 05 of tidal triggering of earthquakes,and the predominant tidal phase for earthquake triggering is- 18. 95°,close to the maximum 0°( new moon and full moon) of the earth tide in monthly scale. Regarding the statistical test result of tidal triggering of earthquakes,a preliminary explanation is given as to why the trigger effect in the east-west direction is greater than that in north-south direction. | Li Jin Jiang Haikun Song Jin Gui Rong Ji Zhanbo Wen Shaoyan | 2014 | Earthquake Research in China2014，28，4： | 0 |
| 4 | Earth Summit Mission 2022:Scientific Expedition and Research on Mt.Qomolangma Helps Reveal the Synergy between Westerly Winds and Monsoon and the Resulting Climatic and Environmental Effects显示文摘“Earth summit mission 2022”is one of the landmark scientific research activities of the Second Tibetan Plateau Scientific Expedition and Research(STEP).This scientific expedition firstly used advanced technology and methods to detect vertical meteorological elements and produce forecasts for mountain climbing.The“Earth summit mission 2022”Qomolangma scientific expedition exceeded an altitude of over 8000 meters for the first time and carried out a comprehensive scientific investigation mission on the summit of Mt.Qomolangma.Among the participants,the westerly–monsoon synergy and influence team stationed in the Mt.Qomolangma region had two tasks:1)detecting the vertical structure of the atmosphere for parameters such as wind,temperature,humidity,and pressure with advanced instruments for high-altitude detection at the Mt.Qomolangma base camp;and 2)observing extreme weather processes to ensure that members of the mountaineering team could successfully reach the top.Through this scientific expedition,a better understanding of the vertical structure and weather characteristics of the complex area of Mt.Qomolangma is gained. | Yaoming MA Weiqiang MA Huaguang DAI Lei ZHANG Fanglin SUN Jinqiang ZHANG Nan YAO Jianan HE Zhixuan BAI Yuejian XUAN Yunshuai ZHANG Yuan YUAN Chenyi YANG Weijun SUN Ping ZHAO Minghu DING Kongju ZHU Jie HU Bian Bazhuga Bai Juepingcuo Zhuo Ma Ren Qingnima Suo Langwangdui Yang Zong Haikun WEN | 2023 | Advances in Atmospheric Sciences2023，40，2： | 0 |
