    A population of highly energetic transient events in the centres of active galaxies

    Recent all-sky surveys have led to the discovery of new types of transients. These include stars disrupted by the central supermassive black hole, and supernovae that are 10–100 times more energetic than typic...

    Helium abundance and asymmetry in the wind from the precursor to supernova 1987A

    TO explain why the progenitor of supernova 1987A exploded as a blue supergiant star, models of stellar evolution require that there must have been extensive mixing into the hydrogen-rich envelope of materials ...

    Carbon monoxide in supernova 1987A

    The identification of carbon monoxide in the infrared spectra of SN1987A (refs 1–4), which exploded on 23 February 1987, represents the first-ever detection of a molecule in a supernova. In infrared spectra ob...

    Speckle interferometric observations of supernova 1987A and of a bright associated source

    The explosion of SN1987A in the Large Magellanic Cloud1 provides a unique opportunity for the direct measurement, by means of interferometry, of the spatial distribution and evolution of the optical emission of ...

    Collisionally Heated Dust in LMC Supernova Remnants

    Preliminary IRAS additional observations (A0s) are presented, which show that luminous (∿ 105 L⊙) infrared sources are associated with supernova remnants. Comparison of the infrared and X-ray data show that the i...

    NGC3256: an emerging elliptical galaxy

    NGC3256 is a spectacular peculiar galaxy, with a highly chaotic nuclear region consisting of several bright knots. Two diffuse tidal tails are visible evidence of violent past history. The galaxy has been clas...

    The ultraluminous interacting galaxy NGC6240

    In the course of checking preliminary lists of IRAS (Infrared Astronomical Satellite) sources to see whether any of the interacting galaxies that we have been studying1 were included, we discovered that the posit...

    Discovery of an IR echo from a supernova dust cloud

    Supernova (SN) 1982g in NGC1332 was discovered by Maza on 28 March 1982 at mpg=14.0 (ref. 1) some 30kpc (Ho = 50 km s−1 Mpc−1) from the nucleus of the parent galaxy (distance, 30Mpc; type, SO)2. No other optical ...

    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 ...

    Upper limits for the radio pulse emission rate from exploding black holes

    IT has been suggested1 that the explosion of a primordial black hole (pbh) might produce a coherent radio pulse detectable at a distance of ∼ 104 pc with a simple antenna. Several searches2–5 for radio pulses arr...

    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 ...

    An Experiment to Search for Prompt Emissions from Supernovae at Microwave Frequencies

    A growing interest in recent years has developed in astronomical phenomena which occur on short time-scales, this interest being sparked off first by the discovery of pulsars, and enhanced by the work of Weber...

    Search for Isolated Radio Pulses from the Galactic Centre at 151.5 MHz

    WE have extended our previous work1 and searched specifically for pulses from the galactic centre (GC), which might be correlated with the events reported by Weber2,3. To discriminate against local interference w...
