w/c: 14 June 2021

Time: TBD
Location: Zoom, YouTube, and Slack

Last year at this time we created the Summer All-Zoom Epoch of Reionization Astronomy Conference (SAZERAC) to react to the sudden consequences of the cancellation of the summer conference circuit due to COVID-19. While we are still in the midst of the pandemic, the astronomical community has rapidly adapted and there are now several online conference offerings planned for summer 2021. As SAZERAC was extremely enjoyable and well received, we are announcing SAZERAC 2, to take place the week of 14 June.

Participation in SAZERAC will be entirely online via zoom, with the option to pre-record talks. All talks will be recorded and posted on our website for later viewing. Discussion and interaction will be facilitated via Slack, enabling those in conflicting time zones or who cannot attend live to interact with speakers and participate in all discussions.

Talk sessions at SAZERAC will focus on variety of topics, observational and theoretical, spanning the epoch of reionization (broadly z > 5), including:

  • Evolution of cosmic star formation
  • Physical conditions of galaxy star-forming environments
  • Constraints on reionization
  • Formation of the first stars and black holes
  • Local analogues of high-redshift galaxies
  • Near-future surveys of the Epoch of Reionization

The format for SAZERAC 2 will broadly be similar to the original. To overcome timezone and childcare constraints, we will meet for 3.5 hours (two 90 minute sessions and 30 min break) each day over four days, beginning on 14 June. These sessions will begin at 1330 UTC (0630/0930 US West/East Coast, 1430 in UK, 2230 in Tokyo). We will hold an additional session at either 0000 or 0800 UTC (depending on demand). The Slack channel allows discussions to continue across time zones. Similar to last year, talks by junior researchers will be prioritized, though we will also welcome some talks by more senior researchers. Finally, we anticipate one session focused on relevant JWST Cycle 1 approved programs.


Links providing access to the SAZERAC Zoom and Slack will be distribution via the SAZERAC mailing list. The maximum number of people accomodated by Zoom is 500 and access is provided on a first-come first-served basis. However, the conference will also live stream via our YouTube channel.
