Spectral energy distributions (SEDs) refer to the distribution of energy emitted by an astronomical object across different wavelengths, ranging from radio waves to gamma rays. SEDs are often used in astrophysics to characterize the properties of celestial objects, such as stars, galaxies, and black holes. By studying the shape and intensity of the SED of an object, researchers can gain insight into its composition, temperature, and physical processes. Spectral energy distributions are typically plotted on a graph with wavelength or frequency on the x-axis and energy flux on the y-axis.
