The image at right is an excitation map of the barred spiral galaxy NGC 1365, as observed with a Fabry-Perot "Tunable Filter." The continuum image shows starlight, Hα and [NII] images show ionized gas emission, and the [NII]/Hα map shows the ratio of collisional to photo- ionization.

The spectrum at right is an example of multi-component fitting of the Hβ to [OIII] 5007 Å emission-line region, including a fit to the stellar continuum.' research[4] = '
The figure at right shows that interacting galaxies with strong starburst activity (blue and red points) fall significantly below the mass-metallicity relation of normal galaxies. The depressed oxygen abundance in these systems is likely due to merger-induced gas inflow. Click here for more on the M-Z relation in interacting galaxies.' research[5] = '
Predictions for the suppression of the nuclear oxygen content in a merger of two equal-mass spiral galaxies. This suppression is particularly prominent after first passage of the two galaxies. Click here for more on the oxygen abundances in interacting galaxies.' research[6] = '
The detection rate, via absorption lines, of galactic winds in interacting galaxies with high star formation rates. The results are consistent with ubiquitous winds and changing morphology with SFR. Click here for more on winds in interacting galaxies .' research[7] = '
The velocity of galactic winds increases as the luminosity of the system increases. These winds appear to be driven mostly by star formation. Click here for more on winds in interacting galaxies.' research[8] = '
The average mid-infrared spectrum of 75 ultraluminous infrared galaxies (ULIRGs), as observed with the Spitzer Space Telescope. ULIRGs are luminous in the mid- and far-infrared, and represent the final stages of a galaxy-galaxy merger.' research[9] = '
Disentangling the contribution of a starburst and supermassive black hole to the luminosity of galaxy-galaxy mergers is challenging.
