Research on the knee region of cosmic ray by using a novel type of electron–neutron detector array
By accurately measuring composition and energy spectrum of cosmic ray, the origin problem of so called “knee” region (energy >one PeV) can be solved. However, up to the present, the results of the spectrum in ...

Galactic interstellar scintillation observed from four globular cluster pulsars by FAST
We report detections of scintillation arcs for pulsars in globular clusters M5, M13 and M15 for the first time using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). From observations of these...

Open AccessAbsorption and scattering of a high dimensional non-commutative black hole
In this work, we investigate the scattering of massless plane scalar waves by the high dimensional non-commutative Schwarzschild–Tangherlini black hole. We use the partial wave approach to determine the scatte...

Absorption and scattering of massless scalar wave from Regular Black Holes
In this work, we numerically investigate the scattering and absorption cross section of the massless scalar field from some well-known regular black holes by using the partial wave approach. Our computational ...

Evidence for three-dimensional spin–velocity alignment in a pulsar
More than 50 years after the discovery of pulsars1 and confirmation of their association with supernova explosions2–4, the origin of the initial spin and velocity of pulsars remains largely a mystery. The typical...

Detection of GRBs at high altitudes with a prototype water Cherenkov detector using single-particle technology
Ground extensive air shower experiment is powerless for detecting cosmic ray particles of tens-GeV energy in the GRBs (Gamma Ray Burst) so far, because of its threshold energy. The experimental altitude needs ...
