GRB group activities

1
GRB group activities

• Science group F2F meeting
• Spalti's Ristorante, 417 California Avenue, Palo
  Alto

2
Group activities

• Study of the LAT performance
• On-ground GRB sensitivity (simulations,
  sensitivity to new model)
• On-board GRB LAT sensitivity detection
  algorithms, collaboration with the Flight
  Software group.
• Possibility of study different selection cuts,
  depending on the Science Case
• On-ground
• detection of faint bursts
• Improvement spectral resolution,
• On-board
• Localization of bright bursts with high energy
  photons
• Changing the OB filter consequently a GBM trigger
  (that provides also a ROI)
• Support to DC2 and other data taken
• Simulation of GRB sources
• Check-outs for Science tools tests
• Multiwavelength observations
• NIR intermediate size-large telescopes for
  follow-up observations
• GeV-TeV connection (inter-group with members from
  GRB, AGN group)
• Importance of GLAST in the determination of the
  high energy spectral index as inputs for TeV (low
  energy threshold) telescopes
• Prospect EBL studies, constrain spectral
  property at high energy (cut-off, HR emission,)

Papers scheduled before the launch

• Simulation development for GLAST.
• This category includes papers which describe how
  the different approaches model the GBM low-energy
  and LAT high-energy emission, as well as the
  general framework for simulating GLAST data
  (Gleam)
• Validation of the simulation codes, and to
  evaluation of the LAT sensitivity, including
  sensitivity to specific spectral distributions.
• Model-dependent sensitivity study
• On-board reconstruction and trigger/localization
  algorithm specific to GRB detection.
• Additional filters applied to realize the GRB
  event buffer
• Trigger/localization algorithms and results
• Analysis of "mock GRB data"
• the LAT Data Challenges
• Expected GRB properties - including spectral,
  temporal, luminosity, and redshift distributions
  - for bursts observable by GLAST.
• Summary paper just before the lounch
• Search for predicted quantum gravity (QG) effect
  in GRB time profiles.
