Le but de l'atelier sera de préparer l'exploitation scientifique du Core Program de SVOM, avec en particulier les aspects suivants :

1. Des produits scientifiques à la publication (lundi 6 mai). En prenant par exemple le cas d'un sursaut gamma brillant détecté par tous les instruments de SVOM et bénéficiant aussi d'un bon suivi par d'autres instruments (associés à SVOM ou non), comment passer du stade de la génération quasi-automatique des produits scientifiques et du recensement des observations complémentaires disponibles à celui de l'exploitation scientifique et de la publication. En particulier, pouvons-nous recenser les outils/compétences/expertises qui sont nécessaires, et s'ils sont déjà présents ou non au sein de notre collaboration. Une liste illustrative mais non exhaustive de sujets pouvant être discutés : analyse détaillée de l'émission prompte, corrections du flux de la rémanence (contribution de la galaxie hôte, absorption dans la galaxie hôte ou dans la Voie Lactée, etc.), interprétation des éventuelles observations disponibles de la galaxie hôte, analyse spectrale et mesure de redshift, analyse et interprétation d'une éventuelle supernova ou kilonova associée, modélisation éventuellement nécessaire à l'interprétation, mise en contexte en termes de populations de sursauts gamma, etc.
2. Organisation du groupe science Core Program (mardi 7 mai): le SVOM Science Working Group effectuera un pilotage à haut niveau mais il faudra un groupe science Core Program pour l’opérationnel de la science sursauts gamma, distinct mais lié au management des activités des Burst Advocates et Instrument Scientist. Cet étage intermédiaire dans notre organisation a été peu discuté jusqu'ici et l'atelier sera l'occasion de le faire, en rappelant également quelle organisation a été mise en oeuvre dans d'autres missions spatiales. 
3. Plan de publication (mardi 7 mai): pouvons-nous commencer à préparer le plan de publication lié à la science Core Program ? Pouvons-nous identifier les sujets prioritaires que nous souhaitons porter ?

L'atelier est ouvert à toute personne associée à SVOM-France et intéressée par la science du Core Program (GRB Studies). Il commencera le lundi à 9h30 et se terminera le mardi après-midi avant 17h. Des pauses café seront organisées et les repas seront à prendre librement dans le quartier.

The aim of the workshop will be to prepare the scientific exploitation of the SVOM Core Program, with particular emphasis on the following aspects:

1. From scientific products to publication (Monday, May 6). Taking, for example, the case of a bright gamma-ray burst detected by all SVOM instruments and also well followed by other instruments (whether associated with SVOM or not), how can we move from the quasi-automatic generation of scientific products and the compilation of available complementary observations to scientific exploitation and publication? In particular, can we list the tools/skills/expertise that are needed, and whether or not they are already present within our collaboration. An illustrative but non-exhaustive list of topics that could be discussed: detailed analysis of prompt emission, afterglow flux corrections (contribution from the host galaxy, absorption in the host galaxy or Milky Way, etc.), interpretation of any available observations of the host galaxy, spectral analysis and redshift measurement, analysis and interpretation of any associated supernova or kilonova, any modeling required for interpretation, contextualization in terms of gamma-ray burst populations, etc.
2. Organization of the science Core Program group (Tuesday, May 7): the SVOM Science Working Group will provide high-level steering, but an operational science Core Program group will be needed for the gamma-ray burst science, separate from but linked to the management of Burst Advocates and Instrument Scientist activities. This intermediate stage in our organization has been little discussed so far, and the workshop will provide an opportunity to do so, while also recalling the organization implemented in other missions such as Swift or Fermi. 
3. Publication plan (Tuesday, May 7): can we start preparing the publication plan for the Core Program Science? Can we identify the priority topics we want to cover?

The workshop is open to anyone associated with SVOM-France and interested in Core Program science. It will start on Monday at 9:30 and finish on Tuesday afternoon before 17h. Coffee breaks will be organized, and meals will be taken freely in the neighborhood.

1 General introduction: objectives of the meeting

Orateur: Prof. Frédéric DAIGNE (Institut d'Astrophysique de Paris - Sorbonne Université)

SVOM-CP Science-Atelier 6-7 mai 2024-intro.pdf

From the production of the science products to the publication: in this session, we propose to consider the case of a bright GRB detected by all instruments of SVOM and to discuss the tools and skills necessary to analyse and discuss this GRB in the context of a publication. (Part I)

Tools/Skills

Working document

2 Introduction: objectives of this session

• short summary of the data available in such a "bright GRB with a slew" scenario
• short summary of the science products generated in the context of the observation of a bright GRB with a slew
• short reminder about the products that were listed in the initial versions of the SR3 document (Scientific Requirements for the Core Program): some advanced products have to be discussed today.
• a clear objective is to identify the skills/tools/... necessary to perform relevant analyses of available data and their interpretation in the context of a scientific publication
• an important objectif is to start to build a list of "experts" within the "French" side of the collaboration, with their skills/tools. A similar work will be done on the Chinese side and this will help future discussion in coming weeks.

11 End of Monday's discussion

12 Introduction: (1) organisation of SVOM Science: SSMP, JWSG, Operational & Scientific Groups ("GRB (population) Studies") - (2) Objectives of the second day of the meeting

• general organisation: (a) SVOM Science Management Plan ; (b) SVOM Joint Science Working Group (JSWG) ; (c) Operational groups ; (d) Scientific groups
• a few words about the operational groups related to core program activities
• a focus on the scientific group "GRB (population) Studies" = the topic of this workshop
• all these groups include Chinese and French colleagues.
• a first goal of the workshop is to discuss the scientific projects that are our priorities in each lab, with the expected contributions we can provide, and with a focus on the projects for the early-career scientists in our groups (PhD students, postdocs) = morning sessions
• a second goal is to discuss a publication plan, at least for the first year(s) = afternoon session
• a last goal is to discuss how we would like to organise the "GRB (population) Studies" group and how we would like to work within it, before starting the discussion with our Chinese colleagues on this topic within the coming weeks (afternoon session).

Orateur: Prof. Frédéric DAIGNE (Institut d'Astrophysique de Paris - Sorbonne Université)

SVOM GRB Studies: our scientific priorities

13 Discussion: which scientific projects are our priorities (in each lab)?

• it would be nice to prepare this session in each group before the workshop to be able to give a synthetic view
• the discussion is of course related to GRB studies, including the physics of the GRB phenomenon and the use of GRBs as a tool for other studies.
• it would be useful to indicate whether potential collaborators have already been identified for certain projects within the Chinese side of the collaboration, or outside.

10:50 Coffee break

14 Discussion: which scientific projects are our priorities (in each lab)? (continued)

15 Lunch break
