# DAWN Summit 2020

## About the Summit

We are pleased to announce the Cosmic Dawn Center Summit 2020 which, due to the current COVID-19 situation, will be held online. For this reason, we have tried to make the event as short as possible.

##### Objective

The purpose of the meeting is to get acquainted with what your colleagues are working on, foster new collaborations, and get an overview of the science of DAWN. There will of course also be time for discussions, but given the unfortunate circumstances, we will have to postpone longer discussions till the crisis is over.

##### Time

The meeting will take place on July 1 and 2, from 15:00 to 18:00 (3 pm to 6 pm) Central European Time. This corresponds to 9 pm to midnight (Western Australian Time) and 7 am to 10 am (Mid-American Time). This time was chosen to make it roughly equally inconvenient for everyone.

##### Structure

We will have nine sessions, corresponding to eight fields of science plus an overview of DAWN's summer program. Each session is kicked off by a short overview (10 minutes, plus 5 for questions/discussion) of the field, with highlights of the past year. Subsequently, anyone working in a more or less related field will have the opportunity to give a brief update (5 minutes including questions) on their work or current projects (see below).

##### Registration

As described below, you're encouraged to present one slide describing your current status. You can submit your slide below, but please go ahead and pre-register already today, since this will make it easier to plan the sessions.

Apart from this, you don't need to register.

##### Venue

A Zoom link will be sent out soon.

##### Survey

Please take this survey. It's the same questions as in 2018, but we'd like to see how our views have evolved.

## Oral contributions

Everybody (scientific staff, students, admins, affiliates, …) is encouraged to give a brief update on their current work. This is not only in order to give your colleagues an idea of your expertise, but also to possibly faciliate collaborations between you.

If you participated in the DAWN Summit 2019 you were asked, prior to the meeting, to submit a single page describing the status of you work. If you did, we apologize that we never really got around to make any use of the page, but we encourage you to use that one-pager as a basis for your update, i.e. to revisit, review, and revise the "plan". As a reward, you can have a minute or two of extra time :)

Due to the short duration of the meeting and the high number of participants, we will each only have 5 minutes, including possible questions and discussion. Moreover, in order to minimize technical issues with shifts between screen sharing, the slides will be collected in a shared presentation, presented by us.

##### Recommended procedure

• Prepare one (1) slide with ~5 bullet points and 1-2 figures.
• Upload your slide using the button below.
• Cover the following topics (not necessarily in this order)
• What do you work with, in general?
• What have you been doing during the last year?
• What will you be doing in the future?
• Would you like to invite for collaborations with other DAWNers, or receive input on specific problems?
• Be prepared to talk for 5 minutes about your slide (incl. time for questions).

To spice up this webpage a little, here's an image of SXDS-27434; the most distant quiescent galaxy ever seen, at a redshift of z = 4.01 (from Tanaka, Valentino, Toft, et al. 2019).

## Registration

If you know you're attending, especially if you know that you'll be giving an oral contribution, it will be very helpful for our planning if you could pre-register.

Once you've made your slide, please submit it using the button below. You can always re-submit if you wish to update your slide.

Please submit your slide by Monday, June 29. Preferably before.
