AKARI-NEP : EFFECTS OF AGN PRESENCE ON SFR ESTIMATES OF GALAXIES

How does the presence of an AGN influence the total SFR estimates of galaxies and change their distribution with respect to the \textit{Galaxy Main Sequence}?To contribute to solving this question, we study a sample of 1133 sources detected in the North Ecliptic Pole field (NEP) by AKARI and Herschel. We create a multi-wavelength dataset for these galaxies and we fit their multi-wavelength Spectral Energy Distribution (SED) using the whole spectral regime (from 0.1 to 500 $\mu$m). We perform the fit using three procedures: \texttt{LePhare} and two optimised codes for identifying AGN tracers from the SED analysis. In this work we present an overview of the comparison between the estimates of the Infrared bolometric luminosities (between 8 and 1000 $\mu$m) and the AGN fractions obtained exploiting these different procedures. In particular, by estimating the AGN contribution in four different wavelength ranges (5-40 $\mu$m, 10-20 $\mu$m, 20-40 $\mu$m and 8-1000 $\mu$m) we show how the presence of an AGN affects the PAH emission by suppressing the ratio $\frac{L_{\rm8~\mu m}}{L_{\rm4.5~\mu m}}$ as a function of the considered wavelength range.
