We have started a project for the study of the AGN/merging connection using Integral Fields Spectroscopy. We have selected a sample of IRAS low-z merger galaxies, candidates to transition objects between luminous IR/mergers and AGNs. We obtained low-resolution integral field spectroscopy of this sample of galaxies in order to study the stellar and ionized gas structures (continuum, absorption and emission lines), and 2D gas kinematics, in order to determine, in each spatial point: (i) the SFR (star formation rate) and history, (ii) gas flows, (iii) disentangle the AGN/merging connection and (iv) looking for hidden AGNs.

我们已经启动了一个利用积分场光谱学研究AGN/Merging连接的项目。我们已经选择了一个IRAS低z合并星系的样本，这些星系是在发光的IR/合并星系和活动星系核之间转换天体的候选星系。我们获得了这一星系样本的低分辨率积分场光谱，以便研究恒星和电离气体结构(连续统、吸收线和发射线)以及2D气体运动学，以便在每个空间点确定：(I)恒星形成速率和历史，(Ii)气体流动，(Iii)解开活动星系核/合并连接和(Iv)寻找隐藏的活动星系核。
