We report the first detection of a TeV gamma-ray flux from the solar disk (6.3$\sigma$), based on 6.1 years of data from the High Altitude Water Cherenkov (HAWC) observatory. The 0.5--2.6 TeV spectrum is well fit by a power law, dN/dE = $A (E/1 \text

Constraints on heavy decaying dark matter from 570 days of LHAASO observations

Autor: LHAASO Collaboration, Ando, S., Chianese, M., Fiorillo, D. F. G., Miele, G., Ng, K. C. Y.

The Kilometer Square Array~(KM2A) of the Large High Altitude Air Shower Observatory (LHAASO) aims at surveying the northern gamma-ray sky at energies above 10 TeV with unprecedented sensitivity. Gamma-ray observations have long been one of the most p

The precise measurement of cosmic-ray antinuclei serves as an important means for identifying the nature of dark matter and other new astrophysical phenomena, and could be used with other cosmic-ray species to understand cosmic-ray production and pro

The Sun at GeV--TeV Energies: A New Laboratory for Astroparticle Physics

Autor: Nisa, M. U., Beacom, J. F., BenZvi, S. Y., Leane, R. K., Linden, T., Ng, K. C. Y., Peter, A. H. G., Zhou, B.

The Sun is an excellent laboratory for astroparticle physics but remains poorly understood at GeV--TeV energies. Despite the immense relevance for both cosmic-ray propagation and dark matter searches, only in recent years has the Sun become a target
