During electron-impact ionization (EII), high-energy electrons collide with atoms, knocking away one or more of their outer electrons. To calculate the probability that ionization will occur during these impacts, researchers use a quantity named the “ionization cross-section.” EII is among the main processes affecting the balance of charges in hot plasma, but so far, its […]
An international joint research team led by the Photonic Network Laboratory of Japan’s National Institute of Information and Communications Technology (NICT) has demonstrated a record-breaking aggregate optical transmission bandwidth of 37.6 THz to enable a new data-rate record of 402 terabits per second in a standard commercially available optical fiber.

Most of us are familiar with the classic example of a liquid-gas moving contact line on a solid surface: a raindrop, sheared by the wind, creeps along a glass windscreen. The contact line’s movements depend on the interplay between viscous and surface tension forces—a relationship that has been thoroughly investigated in experimental fluid mechanics.

Adjusting experimental methods achieved the first “single-shot” diagnosis of electron acceleration through a laser wakefield accelerator along a curved trajectory, according to a recent study led by University of Michigan researchers. The findings are published in the journal Physical Review Letters.

A physicist investigating black holes has found that, in an expanding universe, Einstein’s equations require that the rate of the universe’s expansion at the event horizon of every black hole must be a constant, the same for all black holes. In turn this means that the only energy at the event horizon is dark energy, […]

The Subaru Telescope’s wide and deep imaging observations are contributing information to the New Horizons spacecraft as it moves through the outer solar system. By applying a unique analysis method to images of Kuiper Belt objects taken by the Subaru Telescope’s ultra-wide-field camera, objects that have the potential to extend the Kuiper Belt region have […]
Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new warm sub-Neptune exoplanet, which is nearly three times larger than the Earth. The finding was reported in a research paper published June 13 on the pre-print server arXiv.
