  • Slide 1
  • The Global Telescope Network Phil Plait Sonoma State University
  • Slide 2
  • The Sonoma State University Education and Public Outreach Group (SSU E/PO) Tim Graves Lynn CominskyAurore SimonnetSarah Silva Phil Plait Gordon Spear
  • Slide 3
  • What is E/PO? Education and Public Outreach Formal (in class) and informal activities Posters, flyers, brochures Doodads, gimmicks, doohickeys, and gizmos Websites, articles, etc. Science/astronomy promotion
  • Slide 4
  • Whos Paying For It
  • Slide 5
  • GLAST Observes gamma rays High-energy objects Active galaxies, supernovae, gamma-ray bursts, magnetic neutron stars, polars, solar flares Launches in 2007 (or so), 5+ year mission 350 M$ (+foreign $), with 1% to E/PO Gamma-Ray Large Area Space Telescope
  • Slide 6
  • Active Galaxies Galaxies with unusually bright nuclei Emission lines (narrow and/or broad) Some have jets All appear to have black holes in the middle
  • Slide 7
  • Active Galaxies (2)
  • Slide 8
  • Pulsars Rapidly rotating neutron star Large magnetic field (>10 12 Earth) Many emit gamma rays, as well as radio, optical, X-rays Crab, Vela, GRO J1744-28
  • Slide 9
  • Pulsars (2)
  • Slide 10
  • The GLAST Resort Many or most of these sources emit across the electromagnetic spectrum, but GLAST only sees gamma rays! What can be done about this?
  • Slide 11
  • The Global (nee GLAST) Telescope Network International (multi-longitude) network of ground-based telescopes Purpose: to support GLAST science, and educate students about astronomy Funded through GLAST, but Swift and XMM-Newton are kicking in too Partners: AAVSO, RCT, Elk Creek Observatory, California Academy of Sciences Talking with other groups as well
  • Slide 12
  • Provide short, medium, and long-term baseline observations of interesting targets (pre- and post- launch) Synoptic (concurrent) observations with GLAST (post-launch, duh) Multi-wavelength observations provide insight into physics of energy generation and physical properties of central engines Supporting GLAST Science
  • Slide 13
  • BL Lac: A feisty galaxy on all timescales Years Hours Days
  • Slide 14
  • Potential Science Projects Active galaxy, polar surveillance V and I observations of 2 targets / month S/N >100, photometry ~1% High time-resolution datasets Microvariability Observe one target for many hours At least once/year Gamma-ray bursts Rapid response (GCN notification) High S/N, but fast, multiple images more critical
  • Slide 15
  • Potential Educational Projects Simple image reduction and analysis Hands-On Universe AAVSO cooperation Goal: Publish data in scientific journals
  • Slide 16
  • Resistance is Futile What/Who are we looking for? Observers with access to telescopes w/CCD Willing to observe a minimum amount (depends on project) Willing to have data archived and used by others Not up for a long-term commitment? Go through the AAVSO! Advantages: Work with professionals on cutting-edge science Publishing Info/tutorials on robotic telescopes Receive GTN updates

  • RTS-1, aka Big red Celestron 14/Paramount/ AP47P Pepperwood Ranch, Hume Observatory (California Academy of Sciences) 10 km Santa Rosa, CA
