Prospects for a survey of the Galactic plane with the Cherenkov Telescope Array

CTA Consortium

Approximately one hundred sources of very-high-energy (VHE) gamma rays are known in the Milky Way. A survey of the entire Galactic Plane in the energy range from a few tens of GeV…

The peculiar new state of the blazar PKS 1510-089

H. M. Schutte, M. Zacharias, M. Böttcher +4

Contemporaneous multiwavelength observations with H.E.S.S., SALT, Fermi-LAT, Swift, and ATOM show that the blazar PKS 1510-089 suffered a significant decrease in its optical flux,…

Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array

The Cherenkov Telescope Array Consortium, :, K. Abe +564

Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…

The vanishing of the primary emission region in PKS 1510-089

F. Aharonian, F. Ait Benkhali, J. Aschersleben +152

In July 2021, PKS 1510-089 exhibited a significant flux drop in the high-energy gamma-ray (by a factor 10) and optical (by a factor 5) bands and remained in this low state througho…

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…

Constraining the cosmic-ray pressure in the inner Virgo Cluster using H.E.S.S. observations of M 87

H. E. S. S. Collaboration, :, F. Aharonian +160

The origin of the gamma-ray emission from M87 is currently a matter of debate. This work aims to localize the VHE (100 GeV-100 TeV) gamma-ray emission from M87 and probe a potentia…
