LeMMINGs the eMERLIN radio legacy survey of nearby galaxies

I will present the first data release of high resolution 1.5 GHz radio observations of 103 nearby galaxies with the eMERLIN array, part of the LeMMINGs survey. The sample consists of active and non-active galaxies, taken from the Palomar sample. The radio images reveal a broad variety of morphologies: one/two-sided jets, double-lobed jets, complex str uctures and star formation regions on a typical scale of 100 pc, down to a radio luminosity of 10³² erg/s. The most important result is the detection of pc-scale jetted structures associated with black hole masses down to 10(6) solar mass. By dividing the sample into optical classes, LINERs show more core-brightened radio morphologies and appear to be the scaled-down version of FRI radio galaxies; Seyferts show less collimated jets than LINERs. I will also present new Chandra X-ray data for the sample. I will show how the sample spreads in the X-ray/radio diagram and how the different optical classes can be interpreted based on different disc-jet models. In addition, I also find that that jetted radio sources follow the optical fundamental plane of black hole activity, suggesting a common disc-jet relationship....
