    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...

    The evolution of compact supernova remnants in a strongly magnetized medium
    Two-dimensional simulations of the evolution of supernova remnants in a uniform, high-density medium are presented. The medium is magnetized, and its magnetic...
