摘要：
We report on ESO-VLT near-IR adaptive optics imaging of one radio-loud and two radio quiet quasars at z > 2. In the first case we are able to resolve the QSO and find that it is hosted by an elliptical of M-K = -27.6. This result, though restricted to a single object, extends up to z=2.5 the finding that cosmic evolution of radio-loud hosts follows the trend expected for luminous and massive spheroids undergoing passive evolution.
