SAZERAC 21cm 2022

14-17 March 2022

Location: Zoom, YouTube, and Slack

Due to the sustained interest in SAZERAC we have decided to split this year's main meeting in two with meetings focussing on the 21cm signal and galaxies.

Observations of the 21 cm signal have the potential to provide precision constraints on astrophysics and cosmology from the Dark Ages to the present day (150 >~ z >~ 0). The construction of new radio telescopes over the last decade has led to significant progress including a potential first detection of the sky-averaged 21 cm signal at Cosmic Dawn, physically constraining upper limits on the 21 cm power spectrum during the Epoch of Reionization and detections of the 21 cm signal in cross-correlation at lower redshifts. This SAZERAC meeting will bring the 21 cm cosmology community together to update each other on our work, discuss the remaining challenges ahead and foster new ideas and collaborations. Talk sessions will be organised around the following broad topics:

  • Updates on experiments and observations
  • Analytical and numerical modelling of the signal
  • Instrumental characterisation, modelling and calibration
  • Characterisation and mitigation of foregrounds
  • Theoretical and observational constraints
  • Cross-correlations between the 21-cm line and other signals
  • Prospects for lunar and space-based observations

Registration

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.


Abstract Submission

We invite researchers to submit their abstracts on this topic. During the selection for the contributed talks, priority will be given to graduate students and early-career scientists. To apply to give a talk we invite researchers to submit their abstracts on this topic via this link by 14 February 2022. To participate otherwise you need only sign-up for the general SAZERAC mailing list through which connection info will be shared. Additionally, discussion on the subject is encouraged between the participants through a Slack channel hosted by the SAZERAC team.

Code of Conduct

Attendance at SAZERAC is not a right but a privilege, and attendees are expected to behave professionally. The SAZERAC organizers are committed to providing an atmosphere that encourages the free expression and exchange of scientific ideas.

This document establishes a code of conduct for all attendees of SAZERAC. By participating in SAZERAC in any way, including as an attendee, a presenter, or an organizer, you agree to abide by this code of conduct. Failure to adhere to this code of conduct in all SAZERAC-related circumstances, including in the main session webinars, in the Slack channels, other SAZERAC-related events, or any in person, telephone, or other electronic communication related to SAZERAC, will result in removal from all conference events.

Our scientific community values all members, regardless of (alphabetically) age, cultural background, disability, ethnicity, gender, gender expression, gender identity, marital status, nationality, physical appearance, political affiliation, pregnancy, race, religious beliefs, sexual orientation, socio-economic status, and status as a caregiver (including as a parent). The ability of SAZERAC to allow our community to share its research results and promote the careers of junior attendees depends critically on maintaining a culture of inclusivity, where all voices are respected and heard.

SAZERAC will not tolerate verbal, nonverbal, physical, or sexual harassment or bullying of any kind. Behavior and language acceptable to one person may not be to another. Unwelcome attention, threatening or abusive language, insulting, hurtful, or disrespectful comments, are strictly banned from SAZERAC. Members must make every effort to ensure that words and actions communicate respect for others, regardless of opinion regarding the person or their scientific results.

SAZERAC places a high priority on eliminating sexual harassment in any form from the workplace. As a rule, sexual advancements should not take place in any professional setting, including social events related to a professional event. Members should be especially conscientious of real or perceived power gradients such as seniority, status, or reputation, that may place a member in a vulnerable position.

SAZERAC is not a public event. All attendees must register via the website, and should not share the connection information to Zoom or Slack with non-registered people. When connecting to Zoom or slack, all attendees should use their own name, and not attempt to misrepresent themselves.

During SAZERAC sessions, the Session Chair is in charge. Speakers must keep to their allotted time, ideally using a timer. If they exceed their time, their question time will be reduced, and if they speak through all of the question time, they will be disconnected. When asking questions of speakers, please be professional, courteous, and polite. If a participant engages in obvious harassing behavior during the presentations, the Chairs may take any action they deem appropriate, including warning the offender or removing them from the conference.

SAZERAC participants who believe that they have witnessed or been negatively impacted by a possible violation of the Code of Conduct should contact the SOC by emailing soc@sazerac-conference.org to initiate a complaint, including any available evidence (e.g., screenshots) in their email. If a majority of the SOC concurs that this code has been violated, the offender will be immediately removed from all SAZERAC events. The offender will then be contacted by the SOC, and will have the opportunity to appeal the decision. This appeal will be considered by the SOC, whose decision will be final.
