Milliarcsecond Scale Compactness of Extragalactic Radio Sources at Cosmological Distances
A combination of VSOP pre{launch survey data and our own observations of extremely high redshift quasars provides a data base for studying structural properties of radio{loud quasars as a class of objects. We concentrate our attention on analyzing the compactness of the sources as a function of their redshift (and therefore the emitting frequency) as a precursor to the use of milliarcsecond sca...
متن کاملVLA observations of 6-cm excited OH
The VLA was used to determine precise positions for 4765-MHz OH maser emission sources toward star-forming regions which had been observed about seven months earlier with the Effelsberg 100-meter telescope. The observations were successful for K3-50, DR21EX, W75N, and W49A. No line was detected toward S255: this line had decreased to less than 5 per cent of the flux density observed only seven ...
