Supernova Ejecta with Crystalline Silicate Dust in the Supernova Remnant MSH 15–52
IRAS 15099-5856 in the young supernova remnant (SNR) MSH 15−52 is the first and only SNR-associated object with crystalline silicate dust detected so far, although its nature and the origin of the crystalline silicate are still unclear. In this paper, we

Searches for other vacua. Part I. Bubbles in our universe
We discuss models in which vacua other than our own can be directly observed in the present universe. Models with density-dependent vacuum structure can give rise to ‘non-lethal’-vacua: vacua with lower energy-density than our vacuum, but only in regions

Radioactivity in Supernova Remnants.
We calculate implications of the idea developed by Burbidge et al. that the nearly exponential decrease after the (irst 100 days of the light-curves of Type i supernovae is due to nuclear energy released by the spontaneous fission of Cf354. Uncertainty of the correctness of the Cf-hypothesis qualifies any interpretation of (1) supernovae light-curves, (

Distances to Recent Near-Earth Supernovae from Geological and Lunar 60Fe
Near-Earth supernova blasts which engulf the solar system have left traces of their ejecta in the geological and lunar records. There is now a wealth of data on live radioactive ^60 Fe pointing to a supernova at 3 Myr ago, as well as the recent discovery

Evidence of Gradients of Density and Magnetic Field in the Remnant of Tycho’s Supernova
By using surface brightness maps of Tycho’s supernova remnant (SNR) in radio and X-rays, along with the properties of thermal and synchrotron emission, we have derived the postshock density and magnetic field (MF) strength distributions over the ...
