摘要: We outline the science prospects for gamma-ray bursts (GRBs) with Cherenkov Telescope Array (CTA), next-generation ground-based observatory operating at energies above few tens of GeV. With its low energy threshold, large effective area and rapid slewing capabilities, CTA will be able to measure spectra variability GRBs multi-GeV unprecedented photon statistics, thereby break new ground in elucidating physics GRBs, which is still poorly understood. Such measurements also provide crucial diagnostics ultra-high-energy cosmic ray neutrino production advance observational cosmology by probing high-redshift extragalactic background light intergalactic magnetic fields, contribute fundamental testing Lorentz invariance violation high precision. Aiming quantify these goals, we present some simulated observations GRB curves, together estimates their detection rates CTA. Although expected rate modest, order a per year, hundreds or more high-energy photons burst may attainable once they are detected. address various issues related following up alerts from satellites other facilities CTA, as well follow-up wavelengths. The possibility discovering observing onset including short during wide-field survey mode briefly discussed.
