안녕하십니까.

전파천문본부 정태현 박사님 요청으로 특별 세미나 공지를 전달드립니다.

연사 : Dr. Sheperd Doeleman (Black Hole Institute, Harvard University)

호스트: 정태현 (전파천문본부)

장소 : 장영실홀 331-2호 및 원격연결

일시 : 8월 8일 (월) 오후 2:00 - 3:00

접속주소 : https://us02web.zoom.us/j/84597516884?pwd=OHVjOEQra1lSZ242K2tOZWY4T2Nzdz09

제목: The next-generation Event Horizon Telescope

초록: 

Einstein's theories predict that a distant observer should see a ring of light encircling a black hole, which forms when radiation emitted by infalling hot gas is lensed by the extreme gravity near the event horizon.  The Event Horizon Telescope (EHT) has used the Very Long Baseline Interferometry technique to image two supermassive black holes: M87 and SgrA*.  These results have tested GR at the 10-15% level near the horizon and opened the door to precision studies of black holes.  To advance these efforts, the next-generation EHT (ngEHT) project will quadruple bandwidths, increase observing frequency, and double the number of dishes in the global VLBI array.  These enhancements will allow us to capture the dynamics of black holes through real-time and time-lapse video.  I will describe prior results, and the path to realizing the ngEHT.

Title: The next-generation Event Horizon Telescope

Abstract: 

Einstein's theories predict that a distant observer should see a ring of light encircling a black hole, which forms when radiation emitted by infalling hot gas is lensed by the extreme gravity near the event horizon.  The Event Horizon Telescope (EHT) has used the Very Long Baseline Interferometry technique to image two supermassive black holes: M87 and SgrA*.  These results have tested GR at the 10-15% level near the horizon and opened the door to precision studies of black holes.  To advance these efforts, the next-generation EHT (ngEHT) project will quadruple bandwidths, increase observing frequency, and double the number of dishes in the global VLBI array.  These enhancements will allow us to capture the dynamics of black holes through real-time and time-lapse video.  I will describe prior results, and the path to realizing the ngEHT.

Language : This talk will be given in English.
