Current instruments have passed the critical sensitivity threshold and reveal a rich panorama, but this is clearly only the tip of the iceberg. What big science questions remain?
DM
Big Science Questions Left to Next-Generation Instruments
• Determining– Origin of galactic cosmic-rays– Whether γ-ray binaries emit via wind/jet
• Studying– Star formation regions– Pulsars and PWN – Studying Physics of AGN Jets– Galaxy clusters: the dark side of structure formation
