Rubin Research Bytes

The Rubin Research Bytes (RRB) session consists of 10 parallel Zoom meetings in which four presenters will give three minute flash talks, followed by a ~10 minute moderated Q&A. At 30 minutes, attendees switch to a different Zoom meeting room and the flash talks and Q&A process repeats for another 30 minutes. The entire session is 60 minutes long. All presenters will give their talks twice in the same Zoom room, and all attendees will be able to see and discuss eight flash talks live, in total, by visiting two Zoom rooms. The organizers of this session, Pat Burchat and Fed Bianco, thank you all very much for participating, and welcome you to reach out with comments or questions about the RRB session via email or SlackRecordings of all the RRB flash talk sessions are now available -- find links to recordings for all sessions below.

Instructions for Attendees: Decide in advance which two parallel Zoom meetings you are going to join, and in which order. Feel free to view the slides the night before to prepare constructive questions for our presenters. Join the Slack channel for the parallel sessions you're interested in. During the session's Q&A period, pose your question in the Zoom chat or the Slack channel and wait to be invited to unmute by the session chair. Watch the video recordings or view the slide decks from parallel sessions you were unable to attend live. Continue discussions with presenters and attendees in the associated Slack channels.

Instructions for Presenters: Find your parallel Zoom meeting in the list below, and add your slides to the linked common deck by Mon Aug 10, at noon (i.e., about 24h prior to the session). During the Zoom meeting, the chair will screen-share the slide deck and you will have 3 minutes to speak to your slides. Then all four presenters will take questions from attendees (i.e., panel-style Q&A). Please join the associated Slack channel, where attendees may ask you follow-up questions if the session time runs short.

Instructions for Zoom meeting Chairs: The two chairs will both remain in the same Zoom room for the full hour. Please find your assigned session in the list below. Review the contributed slides on Mon Aug 10 after noon (i.e., about 24h prior to the session) to ensure all the presenters' slides are assembled and in the correct order. Ensure that you can both screen-share the common slide deck during the session (use the "Prep Room" described on the "Connecting" webpage). Be prepared to speak to the content of the first three introductory slides, and to screen share the communal deck throughout all the flash talks. Ensure you have a way to time the 3 minute flash talks. Join the associated Slack channel. One chair should be primarily responsible for screen-sharing the slides and timing, and the other for identifying attendees with questions (via the Zoom chat and Slack channel) and inviting them to unmute to ask their question.

Explicit Agenda to Avoid Potential Confusion:

  • (10:15am, all chairs and presenters join the Zoom room, get organized)
  • 10:30am, ~5 minute welcome, introduction, explanation by session co-chairs
  • 10:35am, ~12 minutes of four back-to-back 3-min flash talks by presenters
  • 10:47am, ~10 minutes panel-style Q&A between attendees and presenters
  • 11:00am, ~2 minutes for attendees to switch rooms
  • 11:02am, ~3 minute welcome by session co-chairs
  • 11:05am, ~12 minutes repeat four back-to-back 3-min flash talks by presenters
  • 11:17am, ~10 minutes panel-style Q&A between attendees and presenters
