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…

Constraints on the intergalactic magnetic field using Fermi-LAT and H.E.S.S. blazar observations

H. E. S. S., Fermi-LAT Collaborations, : +134

Magnetic fields in galaxies and galaxy clusters are believed to be the result of the amplification of intergalactic seed fields during the formation of large-scale structures in th…

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…

Detection of extended gamma-ray emission around the Geminga pulsar with H.E.S.S

H. E. S. S. Collaboration, :, F. Aharonian +165

Geminga is an enigmatic radio-quiet gamma-ray pulsar located at a mere 250 pc distance from Earth. Extended very-high-energy gamma-ray emission around the pulsar was discovered by…

H.E.S.S. follow-up observations of GRB221009A

H. E. S. S. Collaboration, :, F. Aharonian +159

GRB221009A is the brightest gamma-ray burst ever detected. To probe the very-high-energy (VHE, \!100 GeV) emission, the High Energy Stereoscopic System (H.E.S.S.) began observat…

Fermi-GBM Discovery of GRB 221009A: An Extraordinarily Bright GRB from Onset to Afterglow

S. Lesage, P. Veres, M. S. Briggs +136

We report the discovery of GRB 221009A, the highest flux gamma-ray burst ever observed by the Fermi Gamma-ray Burst Monitor (GBM). This GRB has continuous prompt emission lasting m…

The Fermi-LAT Light Curve Repository

S. Abdollahi, M. Ajello, L. Baldini +110

The Fermi Large Area Telescope (LAT) light curve repository (LCR) is a publicly available, continually updated library of gamma-ray light curves of variable Fermi-LAT sources gener…
