New stage in high-energy gamma-ray studies with GAMMA-400 after Fermi-LAT
EPJ Web of Conferences, 2017 Fermi-LAT has made a significant contribution to the study of high-energy gamma-ray diffuse emission and the observations of 3000 discrete sources. However, one third of all gamma-ray sources (both galactic and extragalactic) are unidentified, the data ...

Naked Forward Shock Seen in the TeV Afterglow Data of GRB 221009A
The Astrophysical JournalWe explore the implications of the light curve of the early TeV gamma-ray afterglow of GRB 221009A reported by the LHAASO Collaboration. We show that the reported offset of the reference time, T _* , allows the determination of the activation time of the

The Search For Pulsar Wind Nebulae in the Very High Energy Gamma-ray Regime [PDF]
, 2010 The aim of this Thesis is to study the development of pulsar wind nebulae in the TeV regime and in doing so uncover more sources which have as yet not been observed at these wavelengths.
