Context. We present the discovery of very high energy (VHE, E > 100GeV) gamma-ray emission from the BL Lac object 1ES 1215+303 by the MAGIC telescopes and simultaneous multi-wavele…
MAGIC observations of NGC 4278. The first low-luminosity radio galaxy with compact jets detected at TeV energies
S. Abe, J. Abhir, V. A. Acciari +189
The Large High Altitude Air Shower Observatory (LHAASO) Collaboration has recently reported the first detection at TeV energies of a low-luminosity radio galaxy, NGC 4278. The aim…
Constraints on ultra-high-energy cosmic ray sources from a search for neutrinos above 10 PeV with IceCube
IceCube Collaboration, M. G. Aartsen, K. Abraham +309
We report constraints on the sources of ultra-high-energy cosmic ray (UHECR) above GeV, based on an analysis of seven years of IceCube data. This analysis efficiently sele…
