Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

We present a synthetic rotation curve technique to analyze spatially resolved emission lines from faint galaxies. This algorithm takes into account important variables, such as intrinsic velocity ...

The great thing about having telescopes that can look further and further into the past is being surprised by what we see ...

The researchers measured emission lines of N 2 in the droplet (near 430 ... pulses with durations of less than 285 fs, the emission spectra widened dramatically and an extended pedestal formed ...
