According to modern theories of spectral emission, these lines are due to an atom which has lost one electron. The principal line due to the normal atom of calcium is the g-line 4227, and the ...

Superradiant Smith-Purcell radiation (S-SPR) is a kind of free electron radiation with a train of free electron bunches ...

Unlike standard RGB images with their three channels, these files store information across numerous channels, each ...

Our new study of the nearby starburst galaxy Haro 11 has shown that strong X-ray-emitting superwinds may be a key mechanism ...

However, these pulses exhibit noise in both time and frequency due to the self-amplified spontaneous emission (SASE ... combs with adjustable spectral line spacing and numbers.

Since the James Webb Space Telescope (JWST) began science operations, astronomers have observed galaxies that existed more ...

In every scientific discovery in the movies, a scientist observes something unexpected, scratches the side of his or her ...

Graduate students from the Graduate University for Advanced Studies (SOKENDAI) participated in an observational training ...

To design the UWB pulse, considering the pulse shape is very necessary, and a spectral emission mask of the designed pulse should meet the FCC spectral mask requirement between frequency range 3.1 GHz ...

Abstract: The theory of broadening and shift of the spectral lines including the statistical dependence of Doppler and impact broadenings is developed. One of the results of this theory is the ...

Researchers delved into the curious case of SXP 138, a pulsar in a binary star system whose cosmic clock is not ticking as ...
