    Supernova Dust
    Until the advent in the late 1990’s of sensitive submillimetre arrays such as SCUBA, it was generally thought that the main sources for the interstellar dust...

    Supershells as probe particles for the study of the galactic spin orientation
    Here we describe a method that can be used to derive, with a high degree of confidence, the direction of the rotation axis of a galaxy. The method is based on...

    Survey for the Binary Progenitor in SN1006 and Update on SN1572
    We have completed a survey down to R = 15 mag of the stars within a circle of 4 arcmin radius around the nominal center of the remnant of SN 1006, one of the...

    The Center of the Andromeda Galaxy
    We report on sensitive high-resolution surveys of the central part of the Andromeda galaxy (M31) with Chandra at X-ray wavelengths and with the Very Large Array...

    The Cherenkov Telescope Array potential for the study of young supernova remnants
    Supernova remnants (SNRs) are among the most important targets for γ-ray observatories. Being prominent non-thermal sources, they are very likely responsible...

    The circumstellar medium of the peculiar supernova SN1997ab
    We report the detection of the slow-moving wind into which the compact supernova remnant SN 1997ab is expanding. Echelle spectroscopy provides clear evidence...

    The death and afterlife of massive stars
    Observations of supernovae and gamma-ray bursts show that massive stars end their lives with a wide variety of properties. For supernovae, mass loss plays a...

    The discovery of a supernova type Ia progenitor at the heart of a planetary nebula
    I will report on the results of our paper published in Nature this week, outlining the discovery of a super-Chandrasekhar double-degenerate binary system at the...

    The evolution of a supernova remnant in a strongly magnetized interstellar medium
    Several aspects of the evolution of an SNR into a low-beta ISM are investigated. The presence of a strong magnetic field in the unperturbed ISM is found to have...
