Challenge # 1Challenge # 1
• Need simultaneous multiwavelength data to study variability and emission processes (eg. Active Galactic Nuclei)
F.Longo et al. -- 8
Challenge # 2Challenge # 2
• Need more exposure and optimal timing (and radio monitoring) to discover more gamma-ray PSRs.
F.Longo et al. -- 9
Challenge # 3Challenge # 3
• Need fast timing for gamma-ray detection (improving EGRET deadtime, 100 msec → 100 microsec or less).
Delayed Emission (GRB 940217)
Prompt Emission (GRB 930131)
F.Longo et al. -- 10
Challenge # 4Challenge # 4
• Need arcminute positioning of gamma-ray sources (improving EGRET error box radii by a factor of 2-10).
