An improved upper limit on the neutrino mass from a direct kinematic method by KATRIN
M. Aker, K. Altenmüller, M. Arenz +205
We report on the neutrino mass measurement result from the first four-week science run of the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from…
Diffuse Galactic gamma-ray emission with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +225
Diffuse -ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeV energies over se…
Search for TeV Gamma-ray Emission from GRB 100621A, an extremely bright GRB in X-rays, with H.E.S.S
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +213
The long gamma-ray burst (GRB) 100621A, at the time the brightest X-ray transient ever detected by Swift-XRT in the keV range, has been observed with the H.E.S.S…
The exceptionally powerful TeV gamma-ray emitters in the Large Magellanic Cloud
H. E. S. S. Collaboration, :, A. Abramowski +226
The Large Magellanic Cloud, a satellite galaxy of the Milky Way, has been observed with the High Energy Stereoscopic System (H.E.S.S.) above an energy of 100 billion electron volts…
Discovery of the VHE gamma-ray source HESS J1832-093 in the vicinity of SNR G22.7-0.2
H. E. S. S. Collaboration, :, A. Abramowski +218
The region around the supernova remnant (SNR) W41 contains several TeV sources and has prompted the H.E.S.S. Collaboration to perform deep observations of this field of view. This…
Material radiopurity control in the XENONnT experiment
E. Aprile, K. Abe, F. Agostini +150
The selection of low-radioactive construction materials is of the utmost importance for rare-event searches and thus critical to the XENONnT experiment. Results of an extensive rad…
Projected WIMP Sensitivity of the XENONnT Dark Matter Experiment
The XENON collaboration, E. Aprile, J. Aalbers +137
XENONnT is a dark matter direct detection experiment, utilizing 5.9 t of instrumented liquid xenon, located at the INFN Laboratori Nazionali del Gran Sasso. In this work, we predic…
