    Some crucial X-ray observations — One or two SNR(s) in Crux?

    A new EXOSAT (LE/CMA) observation of the region in Crux (R.A. ∼11h 45m, Dec. ∼-62°) where Markert et al. (1981) reported the existence of two x-ray SNR's is presented. After “cleaning” the CMA field from the p...

    An X-ray study of M51 (NGC 5194) and its companion (NGC 5195)

    Observations of NGC 5194/95 with the Einstein HRI show a very strong nuclear X-ray source, surrounded by a diffuse flux, three point sources and the companion. The diffuse flux, which correlates well with the ...

    Observations of supernova explosions and cosmic rays

    A summary of coordinated observations at various frequencies of two type II and three type I SNe is given. Since type II events emit radio and X-ray radiation in the early phases it is shown how one has data t...

    A study of M100 in X-rays

    During a search for X-ray emission from Supernova 1979c, the parent galaxy M100 (NGC 4321) was repeatedly observed with the IPC and HRI instruments aboard the Einstein X-ray Observatory. The X-ray data reveal ...

    An automated station for the detection of bursts of cosmic origin at VHF and UHF

    An automated system for the detection of bursts of cosmic origin at radio frequencies has been built at Medicina (Bologna). The station, completely independent, is part of a network of observatories based in I...

    Upper limits for the microwave pulsed emission from supernova explosions in clusters of galaxies

    Between 1972 and 1975 an international collaborative search was carried out for prompt 10 GHz emission at the onset of supernovae. The motivations and techniques involved in this effort are described, and the ...

    A review of some radio and microwave searches for transient phenomena in relation to Vela gamma-ray bursts and supernovae

    Radio systems with all sky viewing antennas at 151 MHz were operating at 5 widely spaced stations over the period 1970–1973, during which 19 Vela γ-ray bursts were detected. The records were analysed for each ...
