Parameters Of Interest

We report observations of the atomic hydrogen properties of the barred spiral galaxies NGC 3992 and NGC 4731. These systems were observed in 1980 and 1981 with the VLA telescope of the National Radio Astronomy Observatory. In Table 1 we list the systemic parameters of interest.

From Abell's (1958) list of clusters of galaxies, 137 clusters of distance group 5 were observed at 1410 MHz with the 210 ft radio telescope of the Australian National Radio Astronomy Observatory at Parkes. The detected radio sources were further confirmed hy observations at 2650 MHz with the same telescope and at 408 MHz with the east-west arm of the Mills Cross at the Molonglo Radio Astronomical Observatory. A total of 25 radio sources was detected within 5' arc of the centres of corresponding clusters of galaxies, while the mathematical expectation of the number of random coincidences with clusters is about two or three

AbstractIn August 2017 a new radio telescope, the Ghana Radio Astronomy Observatory (GRAO), was officially inaugurated at Kuntunse, Ghana. The GRAO is a former satellite Earth station and now the first operational station in the African VLBI Network (AVN). The Jodrell Bank Centre for Astrophysics (JBCA), supported by the UK’s STFC/Newton Fund, has developed a new pulsar timing system (Hebe) for the GRAO. We present some aspects of the design of Hebe and an outline of the first pulsar detection at GRAO.

Pulsed radio emission has been detected from the X-ray pulsar J0205+6449 in the SNR 3C 58 at 111 and 88 MHz on radio telescopes of the Pushchino Radio Astronomy Observatory. The dispersion measure DM = 141 pc cm−3 has been confirmed. The synchrotron mechanism is proposed for the radio and X-ray emission to explain the lower X-ray and radio luminosities of this pulsar compared to the Crab pulsar.

This paper gives fiux density measurements of 312 sources at 153 MHz obtained from a general continuum survey made with the 210 ft radio telescope of the Australian National Radio Astronomy Observatory, Parkes, N.S.W. The beamwidth of the telescope at this frequency is 2� 18�. Some discussion of results for spectra is given and a comparison is made with other measurements of the same sources.

Radio observations of Hi8 mainly spiral galaxies have been made at 21 em and additional observations have been made for some at 11 and 75 em. The observations at 11 and 21 cm were made with the CSIR<z 210 ft radio telescope at Parkes and those at 75 cm with the east-west arm of the Mills Cross at the Molonglo Observatory of the University of Sydney. Radio emission was detected from central regions of 20 of the galaxies.

The positions of 33 radio sources previously identified with distant clusters of galaxies were remeasured more accurately to check the identifications. Observations were made at 1410 and 2650 MHz with the 210 ft radio telescope of the Australian National Radio Astronomy Observatory at Parkes, and at 408 MHz with the east-west arm of the Mills Cross at the Molonglo Radio Astronomical Observatory of the University of Sydney. It was found that 21 sources are situated within 5 min of arc of the centres of the corresponding clusters.
