제목 : Gravitational Waves from the Supermassive Black Holes
연사 : 김주한 (KIAS)
초록: We report the preliminary results of the population of Supermassive Black Hole (SMBH) binaries simulated by the Horizon Run 5, the biggest cosmological hydro+gravity simulations ever performed until now. We fit the rate of binary capture events with a modified Schechter function and predicted the number of gravitational wave (GW) events which will be detected by the PTA survey. We have found that GW events will be observed by the PTA at marginal rates as predicted in previous literature.
제목 : Studying Galaxy Clusters with SPHEREx
연사 : 황호성 (SNU)
초록: We plan to use the SPHEREx data for the study of galaxy clusters that are powerful probes of cosmology and structure formation. In detail, we aim to study the physical properties of cluster galaxies through the analysis of spectral energy distributions. This requires well-defined, all-sky catalogs of galaxy clusters and of galaxies. In this talk, we will introduce our effort in this direction. This includes the construction of a galaxy cluster catalog from the list of Planck Sunyaev-Zeldovich sources, and the validity test of the SPHEREx reference catalog for identifying cluster galaxies.
제목 : 알마 망원경과 알마자료 이용법 소개
연사 : 강지현 (KASI)
초록: 알마 망원경은 간섭계 전파망원경으로, 태양계, 행성 및 별 탄생, 외부은하, 우주론 등 다양한 천문학 분야에서 사용되고 있다. 방대한 알마 관측 결과는 과학 연구에 바로 사용가능한 형태로 알마 아카이브에 저장되어 있어 손쉽게 연구에 사용할 수 있다. 또한 관측의 준비와 수행, 자료처리 등을 알마지역센터에서 수행하므로, 전파 외 전공분야 천문학자들도 과학 아이디어를 제안하고 결과를 연구에 사용하기에 편리하다. 이번 발표에서는 알마 망원경을 소개하고, 알마 아카이브 이용법과, 간편하게 알마 자료를 볼 수 있는 툴인 CARTA 사용법 등을 시연하고자 한다.
제목 : The Next Generation of AI in Medical Imaging
연사 : 배현진 (Promedius)
초록: I will discuss the latest advancements in AI and its potential applications in medical imaging. The talk will cover topics such as deep learning techniques for image analysis, the use of AI in diagnostic imaging, and the integration of AI into radiology workflow. I will also touch on the ethical considerations and potential challenges associated with the use of AI in healthcare. The talk aims to provide a comprehensive overview of the current state of AI in medical imaging and its future potential.
제목 : The era of the artificial intelligence
연사 : 김민규 (Promedius)
초록: In comparison to the age of the universe, the history of artificial intelligence (AI) can be traced back to less than a century, starting in the mid-20th century. Despite its relatively short history, the technology of AI has advanced rapidly and is now being applied in a wide range of industries, cultures, and academic fields. Currently, AI is capable of performing tasks such as visual perception, speech recognition, and language translation. As we enter the era of AI, it is important to understand the capabilities of this technology. Through this presentation, I would like to show you the various state of the art applications of the AI, as well as the limitations and future aspects of the technology.
