중력파와 유령입자를 주제로 2개의 대중과학강연 서울시립과학관에서 개최

프레데릭 마리옹 프랑스국립과학연구원 (CNRS) 은메달 수상자인 프레데릭 마리옹 박사가 방한기념으로 자신의 연구분야인 중력파에 대해서 이야기 할 예정이다. 주한 프랑스대사관은 10 5일 금요일 19시 서울시립과학관에서 프레데릭 마리옹 박사와 중성미자전문가인 서선희 박사를 모시고 대중과학강연을 개최한다. 마리옹 박사는 자신의 연구분야인 중력파를 주제로 강연을 할 예정이다. 이 파동은 급격한 천체현상으로 인해 발생하는 시공간파동으로 2015년 최초로 검출되었다. 중력파는 검출이 매우 어려운 물리현상이다. 왜냐하면 이 파동은 거리를 늘리기도 하고 줄이기도 하는 일종의 « 시공간 지진 »을 발생시키는 현상이기 때문이다. 두 번째 강연자인 서선희 박사는 중성미자를 주제로 자신의 연구경험을 들려줄 예정이다. 두 강연은 모두 통역없이 영어로 진행되며 강연이 끝난 후 자유질의응답시간이 마련될 예정이다.

Conferences Dr SEO & Dr MARION – Seoul Science Center

Dr. Frédérique MARION, silver medalist CNRS (National Center for Scientific Research) who will talk about gravitaional waves who will visit Korea. The French Embassy is organising two conferences held by Dr Frédérique Marion on gravitational waves, and the other by Dr Seo Seon-hee on neutrinos.  at the Seoul Science Center on Friday the 5th of October at 7 PM. Dr. MARION will give a lecture about gratitational waves, her research area. These waves whichi are the disturbance of in the fabric of spacetime generated by astronomical phenomenon, have been detected for the first time in 2015. Gravitational waves are a physical phenomenon very complicated to be detected. Because this phenomenon produces supposed “spacetime quake”. Dr. SEO, second lecturer will tlle about neutrinosm her research interests. The two lectures followed by Q & A will be held wholly in English without translation.

Profils of lecturers and overviews of the lectures

Dr. Frédérique MARION is a research director at CNRS. She has been working on gravitational waves and the Virgo Experiment since 1993. She was co-head of the joint analysis group of LIGO and Virgo between 2006 and 2012, whose objectives was to detect gravitational waves. Dr. MARION has been head of the Virgo group at the particle physics laboratory of Annecy (LAPP) of CNRS since 2005. She was part of the LIGO-Virgo joint detection committee that validated the first observation of gravitational waves, made in 2015 and published in 2016. She won in 1998 the CNRS bronze medal and the CNRS silver medal in 2017.

Title: Gravitational waves: listening to the cosmic whisper

Gravitational waves are tiny ripples in space-time, predicted by Einstein and generated in extreme astrophysical events like black hole mergers. Detecting them was a long-time dream finally coming true since 2015, with highly sensitive large-scale interferometers revealing several spectacular sources. Gravitational waves provide scientists with a new cosmic messenger that, combined with others, helps unravel the mysteries of the Universe.

Before Dr. SEO Seon-Hee moved to IBS CUP (Center for Underground Physics) in March, 2018, she was a Brain Korea Assistant Professor at Seoul National University, Department of Physics and Astronomy. She obtained her Ph.D. in 2004 from University of Minnesota working on Fermilab fixed target experiment, E835, studying charmonium. After then Dr. Seon-Hee Seo had been working on IceCube neutrino experiment at Penn State University as a postdoctoral researcher and later at Stockholm University as an assistant professor, pioneering astrophysical tau neutrino search. She then moved to Korea and had been working on RENO (Reactor Experiment for Neutrino Oscillation) experiment since 2012 and playing a critical role in RENO experiment. Dr. SEO Seon-Hee also proposed “the Hyper-K 2nd detector in Korea” in 2016 and the Hyper-K collaboration officially accepted it, and since then she has been leading “the Hyper-K 2nd detector in Korea” group. In IBS CUP, Dr. SEO Seon-Hee is co-leading the NEOS (Neutrinos Experiment for Oscillation at Short Baseline)-II experiment to search for sterile neutrinos. She is the first Korean physicist receiving “FKPPL (France-Korea Particle Physics Laboratory) Korean Female Scientist Award” in 2018.

Title: ‘Ghost Particle’

The Neutrino is a fundamental particle in our universe like quarks and electrons. We live in the sea of neutrinos produced from Big Bang, Sun, and Supernova burst etc. Unlike photons (light) neutrinos interact very rarely so that it is very difficult for us to even know they exist. Sometimes they are also called “the ghost particles of the universe”. Neutrinos come in three flavors: called electron, muon and tau neutrinos. They change their flavors when they travel from one place to another and back again. One can imagine a vanilla ice cream cone here, travels and changes to strawberry ice cream cone over there. How mysterious is that? This is called “neutrino oscillation” and this has been experimentally observed and Nobel Physics Prize in 2015 was awarded to the experiments which discovered neutrino oscillation. In this talk, Dr. SEO Seon-hee will introduce the mysterious neutrino and relevant experiments.
