| 内容記述 | A new method for measurements of radio sources in the universe has been developed; the method consists of the correlation analyses between observing interferometer fringes and the reference fringe to search for the source position. By applying the developed method to observations of 100 km range decameter wavelength interferometer of Tohoku University, with a long integration time more than 30 hours, it is verified that the positions of the decameter radio sources are able to be determined with accuracy of arc second. For the purpose of the verification of the method, mapping of the radio sources Cassiopeia A has been achieved for the first time. The present results also verify that the results of our study, on the determination of the decameter radio pulses, in which the source positions are concluded at the exact center of our galaxy with accuracy of arc second are quite acceptable; the result then supports the hypothesis that radio wave pulses are related to rotating super massive black holes. | |||||
