We had our May DSES Science Meeting over Zoom. The meeting was led by Rich Russel, our DSES Science Lead. These are his presentation slides of the meeting. (The meeting was hosted and coordinated by Floyd Glick and Bill Miller.)
We had 10 participants for this meeting. Some DSES business, work updates, and observing operations was discussed prior to the Science presenation part of the meeting.
Rich’s topic question for the evening was, why did the Event Horizon radio telescope group, who succeeded in 2019 to image a black hole for the first time, chose to observe the supermassive black hole in the active galaxy M87? To figure this out, we learned about what determines the physical size of a black hole, and its observable characteristics. And we learned about what determines the apparent angular resolution of an object in radio astronomy.
The meeting was recorded as a video mp4 file. We’re trying to transition to a new setup with Zoom. You can access the video of the meeting with this link. You can watch the first hour online. However, you can watch the whole meeting by going to the link and then downloading the video. You can then watch it as a video mp4 file.
