The DAWN journal club
What?
The purpose of the journal club is to discuss recent papers in fields related to DAWN's research fields, i.e. high-redshift galaxy evolution, massive galaxies, quenching, the interstellar medium, reionization, simulations, existing and upcoming surveys with HST, ALMA, Euclid and JWST, and more.
Who?
The journal club is for everyone (in particular also DARKers). You're more than welcome to just follow the discussions, but you're also encouraged to occasionally present papers, and to act as a moderator (see below).
If you're a DAWNer, you can find the Zoom link here.
Format
We meet every Monday at 10:30 for 30 minutes. At NBI, we meet in the lounge area, and at DTU we meet in Room 129. You can also join via Zoom. Please log in a few minutes before (!).
During each session we will discuss two articles, presented by two of us.
The discussions will be "chaired" by a moderator. We will take turns on being the moderator, following the list below. Please check to see when it's your time — if you know you're not available at that time, please swap with someone else.
The role of the moderator
We take turns on moderating the sessions, meaning that you should expect to do this once or twice per year. Check the list below to see when it's your turn. Note that the list is subject to changes, in case of canceled sessions. The date should be correct within a month or so, though.
If you prefer not to be on this list, just let the admin know. But if it's your turn, and you suddenly realize you're unable to moderate, please find a substitute yourself.
Before the journal club session,
the moderator should
- Pick two recent papers from the arXiv.
- Find two people that are able to present them.
- To find a person suitable for presenting, you may consult this list of presenters.
- You should find the presenters at the latest the preceding Wednesday, so that they have a chance to prepare the paper.
- Send out a notification to the journal club mailing list using the button below.
During the discussion,
it is the moderator's job to ensure that
- We only spend 15 minutes per paper, and that
- The discussions don't diverge into details that only two people find interesting.
After the discussion,
- please let the next moderator on the list know that they're up next.
- Update the journal club history below (see this guide on how to update this page).
List of moderators
Presenting a paper
Presenting is voluntary
If you're asked to present a paper, you're always free to decline. If you can suggest another presenter or, even better, have another paper you'd like to present, you'll make the moderator happy.
If you prefer not ever to be asked to present a paper, untick the "Journal Clubbers" group in your staff profile (click here, find yourself, click Quick Edit).
What is (not) expected?
Presenting a paper should not be a comprehensive lecture on the paper. You're not even expected to read it all in detail, or to be able to answer all questions. Focus on the parts that you find interesting. The whole discussion, including both your presentation and a possible subsequent discussion, should be no longer than 15 minutes.
History
All the papers we've discussed are listed here.
Once two presenters has been found, the moderator should put the papers in this list (see here how to edit). Latest dates go in the top.
