| Description | LINERs are the most common AGNs in the local universe but their FIR properties are only poorly known. It is believed that most such nuclear emission line regions are situated in hosts with old stellar population and are different from high ionization Seyfert galaxies that show much higher star formation rate (SFR). Recently we found, using Herschel/PACS, that this is not the case in a sample of z=0.3 LINERs that are more luminous than the best studied local LINERs. Many of these sources show L(FIR) as large as 10^11 Lsun and their H-alpha line is extremely week suggesting unusual extinction or a decaying starburst. This proposal suggests a systematic Herschel/PACS study of the most luminous 0.05<z<0.11 LINERs, comparable in their L(AGN) to the z=0.3 LINERs. There are 49 LINERs in this sample and we divided it into two groups according to the distribution of the UV continuum (Galex) light (..nuclear. and ..extended. LINERs). We will be able to 1. measure L(IR) of 10^10 Lsun or larger, 2. compare the FIR luminosity with L(H alpha) to derive the extinction properties, 3. check the validity of D4000 as a sSFR indicator, 4. look for the signature of a decaying starburst and, in general, make a detailed analysis of the FIR-based SF properties of this population that are still completely unknown. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
