An international research team led by the Helmholtz-Zentrum Hereon has, for the first time, succeeded in visualizing and ...

Neil deGrasse Tyson explains how Newton saw gravity as a force, while Einstein revealed it as warped space-time. A clear, ...

Using NuSTAR and XMM-Newton satellites, astronomers from New York University (NYU) Abu Dhabi have observed a pulsar known as ...

In this paper, a novel Eulerian nonlinear beam-wave interaction (BWI) theory considering harmonic interaction of a helix traveling-wave tube (TWT) is developed. Derived from this Eulerian model, the ...

Quantum mechanics looks at how things work at the atomic and subatomic levels, where particles behave in ways that seem ...

This initiative is in turn driven by my frustration with the status quo, namely the notion of dark matter’s existence despite ...

A novel modified angular log-periodic folded waveguide slow wave structure (MALPFW-SWS) is proposed for high-gain traveling wave tubes (TWTs). Each unit of the MALPFW-SWS has different dispersion ...

Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...
