  1. Gamma-Ray Bursts - an interesting ToO target for NAHUAL - Sylvio Klose, Thüringer Landessternwarte Tautenburg

  2. GRBs: The basic picture E ~ 10^50 bis 10^53 erg

  3. Timing is everything for example:

  4. Long and short Gamma-Ray Bursts M ~ 3 M_sun d < 100 km M > 5-10 M_sun d > 100 000 km

  5. Gamma-Ray Burst VHF Localization Alerts Internet satellite The international GRB alert network S band Data andCommands VLT Secondary ground stations • ToO mode • RRM mode Internet Observatories GCN (Gamma-Ray Burst Coordinate Network) Control Center

  6. GRBs as a pathfinder into the high-z universe 71 GRBs Sloan Digital Sky Survey 44000 quasars 3.4 Gyr 1.6 Gyr 1 Gyr

  7. GRBs as very luminous events d = 800 Mpc ! Peter Schnoor, Kiel, Germany

  8. The luminosities of the afterglows

  9. Exploring the ISM in cosmologically remote galaxies

  10. GRBs as a pathfinder into the high-z universe Lyman drop out z = 6.56 z = 6.42 z = 6.29 GRB 050904

  11. GRB 050904 at z=6.29 Subaru 8m

  12. Outlook: What NAHUAL could provide • confirm high-redshift bursts (z > 7) • search for variable spectral lines • search for signals from the GRB progenitor • probe the reionization of the universe All this with a potentially small amount of observing time. timing is everything
