Dear Emma, all, I cc Stefan Ohm, as he manages breakout rooms (Stefan - pls correct if anything I say is wrong). You do not need to request breakout rooms discussing any of the contributions. There will be a breakout room for each talk in the program without a need for you to request this. We ask everyone to register a breakout room for any discussion that is NOT specifically related to a talk. E.g. Sabrina registered one already on Hadronic Background for extended source analysis We would ask the conveners to give a short summary of your group's view on what should be carried out in a Legacy program over the next ~3 years in case a further extension for HESS will be granted. Some groups already discussed this in WG meetings and/or provided the input for the extension document and its confluence annex and there may be no need for any further iteration. However all groups are very welcome to arrange for a breakout session prior to the session on the 29th, when your short summaries are scheduled. Best regards, Stefan

Hi Emma, all, as far as I know Stefan (Ohm) is planning to offer (must not be taken up though by the speaker of the corresponding talk) break-out rooms for every talk presented at the coll meet after the corresponding session. These could be used to discuss specifics on the talk topic. In my last email I was referring to a more general HESS science discussion of each WG for the extension phase, with the request that in the end it would be good if each convener could come up with a ordered list of science priorities that the respective WG would recommend to carry out in the HESS extension phase. My (naiv?) thinking was that each WG (and or jointly with other WGs where there is topical overlap) uses a (or more of needed?) break-out room for such discussions whose results should be then presented (including the priority list recommended by the respective WG) at the Thursday afternoon session. During this Thursday afternoon session there will be also room for discussions. All the best, Anita On 19/04/2021 10:20, Emma de Ona Wilhelmi wrote:

Dear Emma, Thanks for making this overview. I will try to be available for these time slots. The schedule is somewhat tight if some topics are in a row (also if one wants to stretch ones legs and prepare lunch), but in principle doable.

Garret, Fabian , Jacco, Sabrina, could you comment on this? specially to Jacco and Sabrina, how many breakout rooms are you planning to have, and how much would overlap with the ones I am proposing below? we should have some of them in parallel, but it would be good to avoid conflict of interest for important topics Thanks! Emma (… ) Note that the times for talks is quite reduced, similar to the last CM. You can again upload a longer version in Confluence and just discuss a the most relevant points during the live session. Also keep in mind that we can ‘book’ breakout rooms to discuss further. From our wg (+projects with other wg), I think it will be good to have at least those ones: * BR1 - Vela Pulsar (Science paper and new observations) - Chair: EdOW / Arache * BR2 - Westerlund 2 - Discussion on the Interpretation: Detection of a new component coincident with a ‘jet-like’ cloud - Chair: Tim * BR3 - J1908 Discussion on the interpretation and ICRC contribution - Chair: Dima K. * BR4 - Binary observations with HESS: Can HESS provide relevant new information before CTA? - Chair: Dmitry M. / Gerd * BR5 - 47 Tuc - analysis and results : Chair: Jimmy / Nukri * BR6 - W43 - A bright stellar cluster coincident with an extended hess source - Chair: Naomi * BR7 - Westerlund 1 - Discussion on the interpretation  + SNRPP WG - Chair: Lars * BR8 - PeVatrons - Discussion on the Morphology and gammapy Analysis  + SNRPP WG - Chair: Davit * BR9 - Nova - Relevance of the current ULs and handling of new cases + Transients (Fabian?) - Chair: Alison * BR10 - SS 433 - Discussion on the results + Jets (Garret? ) - Chair: Laura I added a tentative chair, please let me (us) know if that’s okay with you, and also if you having such discussion is a good idea. By default, we could add the discussion after the session where the relevant talk is scheduled, although there might be some overlapping. We can try to organise them to optimise the attendance. The slots are the following (and I added tentatively the BRs): 21.04: 15:30 - 16:00 (BR9) 26.04 : 15:30 - 16:00 (BR10) 28.04 : 12:00 - 12:30 / 12:30 - 13:00 / 13:40 - 14:00 / 15:30-16:00 (BR2 / BR3 / BR7* / BR1) 29.04: 12:00 - 12:30 / 12:30 - 13:00 / 13:40 - 14:00 / 15:30-16:00 (BR8 / BR6 / BR4 / BR5) *BR7 is being ‘doodled’ right now.

Please also feel free to adjust the talk/discussion duration of the talks of your WG (I may have over/under-estimated some) as long as all remains within the respective session time. Also please don't forget to ask for break-out rooms (see table on https://hess-confluence.desy.de/confluence/display/HESS/2021+April+virtual+… ) for your HESS Science discussion rounds. A good way to focus these discussions would be to come up in the end with an ordered priority list of the science your WG is envisioning to pursue with HESS over the next years (i.e., if extension is granted). The results of these discussions is foreseen to be presented by each convener in the Thursday (29 April) afternoon session.
