摘要: Emission-line spectra extracted at multiple locations across 39 ultraluminous infrared galaxies have been compiled into a spectrophotometric atlas. Line profiles of H alpha, [N II], [S [O I], beta, and III] are resolved fit jointly with common velocity components. Diagnostic ratios these line fluxes presented in series plots, showing how the Doppler shift, width, gas excitation, surface brightness change fixed position also distance from nucleus. One general characteristic is presence shocked extending many kiloparsecs In some systems, appears as part galactic disk based on its rotation curve. These disks appear primarily during early stages merger. The characteristics integrated presented.
