-------- Forwarded Message -------- Subject: Re: Cosmo-26 - Selection of abstracts - Deadline: 12th May Date: Thu, 7 May 2026 15:57:12 +0000 From: Jorinde Marjolein Van De Vis jorinde.van.de.vis@cern.ch To: cosmo-26@lorentz.leidenuniv.nl cosmo-26@lorentz.leidenuniv.nl CC: Bibhushan Shakya bs475@cornell.edu

Dear Cosmo organizers,

Bibhushan and I made the following first selection for talks to be accepted

10, 102, 182, 133, 40, 93, 136 155, 11, 21, 36, 81, 83, 118, 144, 221, 252, 272, 274, 261, 291, 297, 336, 346.

We have also picked names for posters, but if some of the chosen talks above are moved to other sessions, some of the current poster picks could be promoted to talks.

Best wishes, Jorinde

Dear Conveners for COSMO-26,

Abstract submission is closed, and we have received a total of over 350 abstracts. Now starts the process of selecting contributions for talks and posters in the various parallel tracks. We'd like to provide some instructions to smooth the process. We have timeslots for 200 talks and can accommodate 100 posters.

You should be able to see the talks that indicated your track in your overview (Reviewing Area) on the indico page https://indico.global/event/15863/ https://indico.global/event/15863/. Participants had the option to indicate several tracks for their talk, and many have done so. Talks are judged independently in each track (but you will see the comments from the conveners of the other tracks)

Please consider ALL proposals that are listed in your track. If you think that a talk that appears in your list would be more appropriate in another session THAT THE SUBMITTER DID NOT INDICATE please indicate this with the ‘change track’ action.

These cases should be rare. Note: DO NOT USE THE ‘EDIT TRACK LIST’ button - this will edit the submission move talks in and out of tracks without any confirmation from other conveners or SOC.

When reviewing, you can give a score, and propose to accept or reject the abstract. Also indicate whether you think a poster would be more appropriate. Please use the ‘reject’ button very sparingly, instead use the scores to rank your abstracts, and then discuss with the other conveners of your track to consolidate the rankings together. You can customise the view of the abstract list on indico to show and sort the scores and review status of the abstracts.

Once all your selections are in, the SOC will look for duplicates and come back to you with how many further talk slots you can assign. So please make a generous reserve list from the outset to make this extra step easier.

The scheduling of the programme will be done at a later stage.

Based on the number of submitted abstracts we have made a preliminarily allocation for the number of talks to each track (divided over blocks of 5 talks each).  You can find it at the end of the email.

PLEASE COMPLETE THIS FIRST SELECTION BY MAY12.

If you have any question on the process or on how to use the platform, feel free to reach out.

Thank you once more for your contribution to the conference.

Best wishes, Ana Achucarro, Koen Kuijken, Matthieu Schaller (On behalf of the SOC)
