| Abstract: |
Luminous infrared galaxies (LIRG) have between 1011 and 1012 solar luminosities. The infrared luminosity is the product of the thermal heating of dust in regions of intense star formation or active galactic nuclei. The dust absorbs the ultraviolet and optical radiation, and re-emits in the IR. In order to produce such luminosities the star formation rate (SFR) must be very high, around 17 solar masses per year. In the local Universe, these SFRs are usually produced by interactions between galaxies or mergers.
In this paper, we present the study of the galaxy CIG 302 which is part of a sample of nearby isolated LIRGs galaxies, CIG 302 does not exhibit obvious signs of interaction. Using direct imaging observations in the optical, infrared scanning Fabry-Perot interferometry, as well as images of astronomical archives, we identify the mechanisms at the origin of this excess emission in the IR, in particular the possible presence of a satellite galaxy that fell into the main galaxy disk. |
