Light-year Scale Radio Cores in Four LINER Galaxies
  The LINER galaxies NGC 2911, NGC 3079, NGC 3998, and NGC 6500 were observed at 5 GHz with the European VLBI Network at a resolution of 5 milliarcsecond and found to possess flat-spectrum, variable, high-brightness temperature ($T_{\rm B} > 10^8$ K) radio cores. These radio characteristics reinforce the view that these LINERs host central engines associated with active galactic nuclei.
