A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...
We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and a little bit ...
a continuous distribution of pulses from zero to a certain maximum height which corresponds to the continuous distribution of Compton electrons produced in the absorption of the gamma-rays.
Terrestrial detonation models have been applied to understand type Ia supernovae explosions, revealing that both terrestrial and astrophysical detonations share similar underlying mechanisms.
Compared to hydrogen-rich materials, Gd-based systems uniquely enable simultaneous attenuation of both primary neutrons and secondary gamma rays generated during neutron capture events. When ...
Ultrahigh energy cosmic rays are the highest-energy particles in the Universe, whose energies are more than a million times what can be achieved by humans. While the existence of ultrahigh energy ...
Harvard astronomer Avi Loeb discusses how scientists trace the cosmic journey of high-energy neutrinos from the Big Bang to ...
Recent flights by NASA’s ER-2 aircraft have uncovered new types of gamma rays generated by thunderstorms. These observations indicate that gamma-ray glows are more common and long-lasting than ...
The thicker the substance, the more the radiation is absorbed. Alpha, beta and gamma radiations penetrate materials in different ways. Alpha radiation is the least penetrating. It can be stopped ...
