Infrared astronomy, study of astronomical objects through observations of the infrared radiation that they emit. The spectral class assigned to each of these stellar spectra is listed at the left of the picture. A spectrograph is an instrument used to obtain and record an astronomical spectrum. ~TildeLink()l lines result from discrete changes in the energy of an atom or molecule.

Astrophysics graduate student programs Vera Rubin in the early 1970s measured the rotation rate of over 60 galaxies. The strong line at 1.28 microns is the Pa-beta hydrogen recombination line, while the feature at 1.255 microns is due to [FeII]. Note the absorption lines for the Balmer Series. A spectral energy distribution (SED) is a plot of energy versus frequency or wavelength of light (not to be confused with a 'spectrum' of flux density vs frequency or wavelength).
