Distributed Telescope Network Research Papers

THE CORE THESIS: What Distributed Networks Can Do That Single Telescopes Cannot

Your network is irreplaceable because: 1. Simultaneity - Multiple sites observe same event at same moment (parallax, triangulation) 2. Geographic distribution - Weather immunity, 24-hour coverage, longitude baseline 3. Temporal density - Coordinated high-cadence that no single facility can sustain 4. Follow-up capacity - LSST will discover ~10 million transients/night but can't follow any

  2. TTV maintenance is already proven - ExoClock shows amateur networks work
  3. GW follow-up needs more eyes - Professional networks are oversubscribed
  4. The follow-up bottleneck is real - Every paper about LSST mentions it
  5. Simple scheduling works - Pull model, dumb nodes, smart center
