SED modeling, or spectral energy distribution modeling, is a method used in astrophysics to analyze the emission of light from astronomical objects over a broad range of wavelengths. This technique involves constructing a model of the object's spectrum based on observations of its brightness at different wavelengths, allowing researchers to infer important physical properties such as temperature, mass, and composition. SED modeling is commonly used to study a variety of astronomical objects, including stars, galaxies, and black holes, and can provide valuable insights into their evolution and properties.
