Revisiting Two Decades of GRB Observations: Assessing Missed Very High-Energy Detections and Future Prospects

Halim Ashkar, Stephen Fegan, Aurélie Sangaré

Gamma-ray bursts (GRBs) are bright flashes of electromagnetic radiation originating from the core collapse of massive stars or the merger of compact objects. It has long been theor…

Sensitivity of the Cherenkov Telescope Array to TeV photon emission from the Large Magellanic Cloud

The Cherenkov Telescope Array Consortium

A deep survey of the Large Magellanic Cloud at ~0.1-100TeV photon energies with the Cherenkov Telescope Array is planned. We assess the detection prospects based on a model for the…
