[Ultra] Luminous InfraRed Galaxies (LIRGs and ULIRGs) have the highest star formation rate among star forming galaxies. Using the infrared (IR) data from the AKARI Deep Field-South (ADF-S) enriched with the data from other instruments, including the Herschel satellite, (8μm-10³μm), we model Spectral Energy Distributions (SEDs) of these galaxies. We apply the CMCIRSED model (Caitlin M. Casey InfraRed Spectral Energy Distribution (Casey, 2012)) and the FUV-to-FIR models included in the CIGALE1code (Code Investigating GALaxy Emission Noll et al. 2009; Serra et al. 2011) code version v0.5 to estimate stellar mass, dust mass and dust temperatures in [U]LIRGs. We concluded that [U]LIRGs have more dust than normal galaxies but the dust temperature does not change significantly with its mass.
