Abstract
Recent results from observations of the southern sky objects are summa rized. The unpulsed, persistent very high energy (VHE) emission from t he gamma ray pulsars, the Crab and PSR1706-44, is discussed. A process of energetic electrons ejection may take place from a variety of othe r objects such as from X-ray binaries, similarly to the pulsars. Such an effect may be seen also in ''pair halos'' around extragalactic VHE gamma ray emitters, the observational study of which is still in a pre liminary stage in the southern hemisphere.
