Abstract
In this work, X-ray data for a sample of 59 luminous infrared galaxies (LIRGs),
obtained with the Chandra X-ray Observatory is presented. These are observations
of the lower luminosity portion of the Great Observatory All-sky LIRG Survey
(GOALS), which includes the most luminous infrared selected galaxies, log(Lir=L )
11:05, in the local universe, z 0:088.With combined X-ray and mid infrared diagnostics
for AGN, AGN are found in 32 % of the objects. Objects without traces of
AGN appear to be underluminous in X-rays, compared to the previously derived far
infrared and X-ray correlations for starburst galaxies at lower star formation rates.
Our results suggest the previous claim that star formation rate can be directly inferred
from X-ray luminosity may not hold for dusty galaxies like LIRGs.
