Dropout (astronomy)
text:
In astronomy, dropout is a radiation source whose radiation intensity falls off sharply below a specific wavelength. The source will be easily visible when its light is filtered to wavelengths longer than the cutoff value, but will "drop out" of the image when it is filtered to wavelengths shorter than the threshold. This is a standard method for locating distant galaxies in deep field images. Because the hydrogen that surrounds the galaxies absorbs light with a wavelength around 100 nanometers,
