LeMMINGs II e-MERLIN survey of nearby galaxies

We present the second data release of high-resolution (==10^17.6^W/Hz, regardless of the host and nuclear type: we detect radio emission >=0.25mJy/beam for 125/280 galaxies (44.6 per cent) with sizes of typically =<100pc. Of those 125, 106 targets show a core which coincides within 1.2arcsec with the optical nucleus. Although we observed mostly cores, around one third of the detected galaxies features jetted morphologies. The detected radio core luminosities of the sample range between ~10^34^ and 10^40^erg/s. LINERs and Seyferts are the most luminous sources, whereas HII galaxies are the least. LINERs show FR I-like core-brightened radio structures while Seyferts reveal the highest fraction of symmetric morphologies. The majority of HII galaxies have single radio core or complex extended structures, which probably conceal a nuclear starburst and/or a weak active nucleus (seven of them show clear jets). ALGs, which are typically found in evolved ellipticals, although the least numerous, exhibit on average the most luminous radio structures, similar to LINERs.
