• Gordon Spear
• Lynn Cominsky
• SSU EPO Team

2
The Gamma-ray Large Area Space Telescope

• A NASA facility-class mission scheduled for
  launch in 2006.
• Large Area Telescope
• Burst Alert Telescope
• Will observe
• Active Galactic Nuclei
• Gamma Ray Bursts
• Diffuse background emission

3
Swift Gamma Ray Burst Satellite

• A NASA mission scheduled for launch in September
  2003
• Burst Alert Telescope (BAT)
• Ultraviolet/Optical Telescope (UVOT)
• X-ray Telescope (XRT)
• Will observe gamma-ray bursts in three parts of
  the EM Spectrum

Active Galactic Nuclei

• Galaxies with massive black holes in the center
• Gravity is so strong inside its event horizon
  that not even light can escape

Gamma-ray Bursts

• Largest explosion since the Big Bang
• A billion trillion times the energy from the Sun
• Signals the birth of a black hole

6
The GLAST Telescope Network

• A series of institutional and amateur grade
  telescopes designed for use by public school
  students in collaboration with GLAST scientists.
• All telescopes are 100 accessible from the
  internet.
• All data is being archived at the Stanford Linear
  Accelerator Center (SLAC), currently the largest
  known database in the world.

7
The GTN Prototype Telescope here at SSU

• A 14 Celestron Schmidt-Cassegrain telescope.
• Paramount ME Telescope mount.
• High-resolution low- noise Apogee CCD.

8
The GTN at Kitt Peak National Observatory

• We are here!

9
Robotically Controlled Telescope (RCT)

• 1.3 meter telescope
• 4 megapixel CCD
• 1/3 of all its time is dedicated to observe
  Active Galactic Nuclei (major GLAST objective)

Archive Development Here at SSU
11
The GTN Archive Client and Server

• Developed in Java 2 v.1.4.1.
• 100 platform independent.
• Features
• Automatic FITS header format
• FITS header validation
• Manual and automatic upload mode
• SSL Encrypted Connection
• Future elimination of client/server protocol
  needs with RMI.

• Server
• Receives the data from the client and inserts it
  into the SLAC Database.
• Client
• Interface for user
• Filter for poorly formatted data
