The FIR-Radio Correlation of Wolf-Rayet Galaxies and the Role of Star Formation in LINERs


Abstract in English

We find that a preliminary classification of LINERs energetics may be made in terms of the FIR-radio correlation of Wolf-Rayet galaxies. The AGN- or starburst-supported LINERs can be distinguished by their FIR-to-radio ratio, $Qequiv L(1.4{rm GHz})/$ $L(60mu{rm m})>$ or $<0.01$. It is interesting to note that almost all the LINERs with inner rings might be starburst- supported, indicating reduced AGN activities compared with those of the AGN-supported ones. We also find that a shock-heating phase for the warm dust component might be important for some starbursts at the burst age of $ge 10^{7}$ yr, with $Q<0.001$.
