Abstracts submitted by large collaborations
There is no strict limitation on the number of contributions for large Collaborations. However, there will be a practical limit in total number of contributions (about 1500).
As for past conferences, it is up to the International Science Program Committee (ISPC) to assess the contributions (based on the abstracts) and rank them according to quality and relevance. If participants submit too many abstracts, some weaker contributions will drop out at the end. In the past the ISPC limited the number of contributions for large collaborations to about 35-40. This is of the order of 3% of the whole conference.
Even a big and productive collaboration should be able to describe their results and achievements in 40 contributions. It would be a great help if a collaboration itself limits and ranks their own contributions to ensure that the most important results are presented. If too many are submitted the ISPC may decide for you which ones are relegated to posters or even drop out.
The ICRC has an emphasis on physics results over plans for the future. Future experiments are not yet taking data, so much work is on the science potential, theoretical work and on technology. As important as this work is, certainly not all of it can possibly be presented as a contribution. Of course, every participant is free to submit abstracts, and perhaps not all minor results have to be collaboration papers.
It does not make sense to submit too many contributions. It would overwhelm the ISPC, the rapporteurs, the proceedings team and, not least, the participants who could not work through a too large amount of presentations.
Collaborations or groups of scientists should think about offering a highlight talk (plenary 25+5 min) with some key results and a good speaker. If a collaboration/group submits many interesting results as abstracts, they have a good argument to ask for a highlight talk, even though plenary highlight talks are limited, too. Also here, the ISPC determines the highlight talks.
As for past conferences, the ISPC will likely classify around 1/3 of the contributions as talks and 2/3 as posters.
To Edit your abstracts go to the bottom of the Abstract Submission page. There you will find a list of your abstracts. By clicking on one, more details will show. Here, you can find the Edit button, which is located right next to the withdraw button. By clicking on it, a form will open and you can make the necessary changes to your abstract. Don't forget to save at the bottom of the form. This editing option is only available while the abstract submission is open.
Chat tool for Q&A
More information will follow soon.
Please, answer to comments and questions your contribution might attract in the commenting tool within one day.
"Short talks" and "Posters".
Each person can have maximum 3 abstracts they pay for. It is ok to be co-author of several others …
The person paying for is supposed to be the main contact for the contribution and also the presenter.
Contributions will be made available one week before the conference (5 July 2021) with the following materials:
- slide/s (pdf) of your talk or poster (pdf, landscape)
- pre-recorded talk (.mp4 file, 12 min for talks, 2 min for poster flash talks)
- proceedings article (pdf, max 8 pages, using LaTeX or Word template)
- schedule, if contribution was included in a discussion session
Please, answer within a day to comments and questions your contribution might attract in the commenting tool.
If your contribution is included for discussion in one of the parallel discussion sessions, you are expected to be present to answer and explain. The contributions involved in any of the discussion sessions will appear on the indico well before the session.
What exactly are the discussions sessions for?
Contributions (Short talks and Posters) are prepared electronically.
- slides and pre-recorded talks are uploaded and visible all the time
- Posters and 2-min flash talks also are available electronically
For most, a long sequence of scheduled talks will not be attractive to be followed at early or late times of the day. Therefore, with all contribution online, you can pick the ones you are interested in, at any time at your leisure. We will make a big effort to get the discussion session going well:
Scheduling of Contributions
There are no sessions where all those contributions are scheduled one after the other, or are to be viewed at the same time in the same virtual room. Everyone is free to see any talk at any time and comment and ask questions via the chat tool. Questions and comments should be addressed by the author within a day.
The parallel sessions are largely discussion sessions around interesting topics (e.g. photo detectors, particle acceleration in AGN jets, TeV GRBs, …). The selection of topics will be done by the International Scientific Program Committee on the basis of the incoming abstracts.
- 5x parallel 12 time slots = 60 sessions of 90 min each
- For each discussion session there will be a convener / discussion leader
- The convener picks from the contributions those that relate to the topic.
- The contributions for a session are listed before in Indico, so that everybody can see its content.
- Besides the convener, the following persons should ideally be present in the session:
- The speaker of the selected contributions
- those who asked questions or commented on the selected contributions in the chat tool.
- those who are interested in the discussion
- Participants in the discussion session should ideally have looked at the contributions and the corresponding chats before the session.
- During the discussion session, each of these contributions are introduced (not more than a minute)
- If the discussion stalls, some time could be used to actually give presentations of selected contributions (talks and poster flash talks).
Price for Attending (per person)
Price for Attending (per person) after 1. July 2021
Price for each contribution
For undergrads and young scientists discounts are available.
With a participation of more than about 700 persons/contributions, the income would allow reduction of the fees. We will give an appropriate discount, once all abstracts are assessed, and before invoices for payments are sent out (around end of April).
Fee reduction for Young scientists & Undergraduate students
We offer a limited number of discounted rates for young scientists with accepted contributions from developing countries. Young scientists are Phd students or postdocs on their first contract. Please apply to firstname.lastname@example.org (with e-mail subject: "discounted rate") within a week of the acceptance of your contribution, with a letter explaining your need, a CV with publication list and a supporting letter by your supervisor.
For undergraduate students (master, bachelor, NO Phd students) we offer free participation in all parts of the conference. Please register, send a scan of your valid student card (with photo) and your program of study and semester (preferably in english) to email@example.com (with e-mail subject: "free undergraduate access"). Note: To present a paper you still need to pay the paper fee.
Highlight talks are selected by the International Scientific Program Committee (ISPC) upon receiving abstracts for contributions (short talks and posters) from the community. If a collaboration (or a group of individuals) has a number of interesting results that would warrant a longer plenary presentation, they should request a highlight talk by sending a mail to firstname.lastname@example.org. They should still submit abstracts for the individual results, but note in the comments field that a specific abstract would be presented in a certain highlight talk. Once ISPC has given a highlight talk, the proposing collaboration (or group) is largely free to select what to present and who is presenting it.
Indico is the platform via which the access to the conference is granted, and all information and materials regarding ICRC 2021 will be shared. You need an account for the DESY Indico system. If you do not have a DESY Indico account yet, please register at:
Materials are all datasets belonging to a contribution or plenary presentation: abstracts, slides, pre-recorded talks, posters, proceedings articles, questions and answers in the chat tool. During the conference, you will find all materials in Indico, through the Timetable or the Contribution List. Access will be opened a week before the official start of the conference. All materials remain accessible after the conference.
Materials for each contribution need to be uploaded by 5 July 2021.
To upload your materials, visit the My Contributions page in the menu on the left. You will be able to see this page after one of your abstracts has been accepted. On this page you will find a list of your accepted abstracts. By clicking on the name of your submission, a new page will open where you can find detailed information on your talk.
On the right of "Presentation Materials" you will find an "edit button" which will open up a menu, with which you can upload files such as your slides or poster (PDF).
To upload your proceeding article.
Outreach & Education
For the first time, the ICRC invites explicitly contributions on Outreach & Education in Astroparticle Physics. Communicating scientific issues to the public has become an essential part of research. As current developments show, this is an important bridge to society showing the value of science.
Submit your projects to share experiences and provide inspiration for others.
Plenary talks are Invited Reviews, Highlight Talks and Rapporteur Talks.
Talks will be either pre-recorded (preferred) and live streamed or recorded live during the official event.
Deadline for Proceedings submission is 15 September 2021.
These videos will remain accessible after the conference.
We will not have dedicated poster sessions. All posters will be accessible throughout the conference on Indico.
- The pdf of the actual poster,
- a pre-recorded 2-min flash talk on what the poster is about and
- the proceedings article give all the relevant information.
- Via the chat tool questions and comments can be posed which the presenter is supposed to answer with short turnaround time (max 1 day).
Posters fitting to the topic of one of the ~60 discussion sessions are scheduled for open discussion, where the presenter should attend.
Upload (preliminary version)
Upload (final version)
The templates for the proceedings can be downloaded from here [ZIP] in formats of LaTeX and OpenDocumentText. Authors presenting on behalf of a collaboration have the possibility to provide a full list of collaboration authors at the end of the pdf contribution which will not count against the page limit. In addition, the collaborations can submit a xml-file of their author list to publish this information in the DOI reference. Details on how to provide these xml files can be found later here or contact email@example.com.
Recording a talk
Here some guidance on how to pre-record your talks for the ICRC using commonly available tools.
Ideally, use a microphone close to your mouth. This is usually producing a much better quality than a built-in microphone of a laptop with noisy ventilators and key strokes.
In the end check that you stay within the allocated time (12-min or 2-min) and size (tba) and that your voice is loud and clear. Repeat the recording, if the result is not sufficient.
With Zoom this is straight forward. Get a free version of Zoom, open a meeting. Share your screen with the presentation, and chose a display option showing the slides and the speaker. Press the record button and start. After ending the Zoom session an .mp4 file is created. Check that you do not run over time and the sound is loud and clear. Upload only good quality recordings.

Prepare videos for upload
Please check the size of your recording. With Zoom, recordings are typically no more than about 5 MB per minute of recording. If you recording is much larger than that, you may want to reduce the size of the videos before uploading them to keep the amount of data created when producing videos for upload reasonably small. This guide (follow soon) shows how to do this.
