FAQ (about the Journal-Club)

• its goal is to allow us to discuss recent papers, taking advantage of the many topics and expertises developed in the lab.
• it's an opportunity for students to 'give' talks and ask questions.
• feel free to attend and contribute in English (but be aware that French is the default language).
• it is open to everybody and any subject, though the focus is on astroparticle physics and cosmology.

A quoi ça sert ? L'idée du journal club est de se tenir au courant de l'actualité scientifique par le biais de discussions autour d'articles vus sur ​http://arxiv.org/ (ou ​http://slac.stanford.edu/spires/ si vous préférez). Il s'agit donc d'encourager la prise de parole dans une atmosphère conviviale, d'échanger, de partager nos expertises, nos questions... afin de faire vivre encore plus la vie scientifique au labo !

Mode opératoire :

• Quand ? Tous les vendredis à 11h00 (la date du Journal Club à venir apparaît toujours en bleu/gras ci-dessous)
• Comment ? Dès que la date de la séance suivante est affichée, éditez ce Wiki et ajoutez un lien vers le papier désiré (suivre les instructions ici si vous ne pouvez pas éditer ce Wiki) :
  1. Cliquez sur connexion (haut à droite)
  2. Cliquez sur Modifier la page (bas à gauche) pour éditer ce Wiki et ajouter votre lien
  3. Cliquez sur Enregistrer les modifications (bas au milieu)... c'est fini !
• Et ensuite ? Une séance dure au plus 1h. Chaque papier pourra être présenté/discuté pendant 10-15 mn (en fonction du nombre). L'idée est de faire ressortir les idées principales du papier, montrer les courbes les plus importantes et nous dire pourquoi ce papier vous a interpelé (libre à chacun d'être plus ambitieux). Il peut s'agir d'un résultat expérimental, observationnel, d'une simulation, de phéno/théorie, de méthodes/outils...
• Modalité d'inscription Le Journal Club est ouvert à tous, mais notez bien qu'il s'agira de discuter de sujets reliés aux astro-particules ou à la cosmologie (sauf événement scientifique exceptionnel). Pour les prises de parole/questions, nous choisirons délibérément de donner la priorité aux doctorants. Venez nombreux !
