HAPPJ 😀
Welcome to the High-energy AstroParticle Physics Journal Club (HAPPJ)!
Our weekly meetings are primarily meant for sharing work in progress, new ideas, early results, puzzles you’re stuck on, and generally anything you’d like feedback on from the group. From time to time, we also discuss a paper, when it feels useful to trigger debate and new perspectives.
Time: Every Thursday at 2:15 PM, L’Aquila Local Time.
Location: GSSI Zenith Building, Room P2.6.
We are committed to keep our meetings lasting no more than one hour.
To participate and receive regular updates on dates and topics, please consider joining our ML.
