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)

Dear all,
Thanks for all the efforts deployed advertising the conference!
You will have seen the email sent to the conveners (below) already.
If you are curious, I have attached the final breakdown of the talks in the various tracks. Note that the sum of all tracks' counts is larger than the total number of abstracts received (361) as most talks used multiple keywords.
Best, Matthieu

Dear conveners for COSMO-26, Dear colleagues,
We just wanted to send you a reminder for the upcoming deadline (12th May) for the selection of abstracts in your track. Having your joint opinions on the talks submitted ensures a high level of quality for the conference as a whole.
Thanks to everyone who already sent in their tracks' ranked list and/or filled in all the grades on Indico. Your swift work is greatly appreciated!
Best wishes, Matthieu (On behalf of the SOC)

Dear organisers,
Please find attached our recommendations for the Dark Matter session at COSMO-26.
We have proposed to accept 30 talks, as well as providing a list of talk reserves, accepted posters, and finally a selection of abstracts that we felt were better suited to other tracks, but that we would accept on the reserve list or poster list in the Dark Matter session if other tracks did not take them.
There were a few rankings we did on indico while figuring out our grading strategy, but please ignore any Dark Matter indico suggestions and take our spreadsheet recommendations as final.
Please let us know if you have any queries.
Best wishes, Pippa, Bradley and Leszek
