Abstract
We present MERLIN, global VLBI and VLBA observations of the high-luminosity, compact steep-spectrum quasar B1524-136 at cm wavelengths. These observations reveal well-defined radio jets on both sides of the active nucleus, a situation which is almost unique amongst high-luminosity radio quasars. However, the radio jets on opposite sides are very dissimilar, and the overall radio structure appears highly distorted. We discuss possible implications of these observations.


Key words: galaxies: active -- galaxies: jets -- galaxies: nuclei -- quasars: general -- quasars: individual: B1524-136  -- radio continuum: galaxies
