Direct detection of a break in the teraelectronvolt cosmic-ray spectrum of electrons and positrons [PDF]

Nature, 2017
High-energy cosmic-ray electrons and positrons (CREs), which lose energy quickly during their propagation, provide a probe of Galactic high-energy processes and may enable the observation of phenomena such as dark-matter particle annihilation or decay ...

Is non-particle dark matter equation of state parameter evolving with time?

European Physical Journal C: Particles and Fields, 2021
Recently, the so-called Hubble Tension, i.e. the mismatch between the local and the cosmological measurements of the Hubble parameter, has been resolved when non-particle dark matter is considered which has a negative equation of state parameter ...

An interacting molecular cloud scenario for production of gamma-rays and neutrinos from MAGIC J1835-069, and MAGIC J1837-073

European Physical Journal C: Particles and Fields, 2021
Recently the MAGIC telescope observed three TeV gamma-ray extended sources in the galactic plane in the neighborhood of radio SNR G24.7+0.6. Among them, the PWN HESS J1837-069 was detected earlier by the HESS observatory during its first galactic plane ...

Investigating an angular correlation between nearby starburst galaxies and UHECRs with the Telescope Array experiment [PDF]

EPJ Web of Conferences, 2019
The arrival directions of cosmic rays detected by the Pierre Auger Observatory (Auger) with energies above 39 EeV were recently reported to correlate with the positions of 23 nearby starburst galaxies (SBGs): in their best-fit model, 9.7% of the cosmic ...

Design and operation of a 1500-m laser strainmeter installed at an underground site in Kamioka, Japan

Earth, Planets and Space, 2017
A laser strainmeter with a 1500-m baseline was constructed at an underground site in Kamioka, Gifu Prefecture, Japan, and has been operating since August 2016. The laser interferometer measures the change in distance between two retroreflectors housed in
