    The Massive Progenitor of the Possible Type II-Linear Supernova 2009hd in Messier 66
    We present early- and late-time photometric and spectroscopic observations of supernova (SN) 2009hd in the nearby spiral galaxy NGC 3627 (M66). This SN is one...

    The nearest extreme starburst: bubbles, young star clusters and outflow in the merger NGC 3256
    We have studied the extreme starburst in the infrared merger NGC 3256. We detect four galactic bubbles (using ESO New Technology Telescope and Hubble Space...

    The optical SN 2012bz associated with the long GRB 120422A
    Aims: The association of Type Ic supernovae (SNe) with long-duration gamma-ray bursts (GRBs) is well established. We endeavor, through accurate ground-based...

    The Origin and Evolution of the Black Hole Binary XTE J1118+480
    Black hole X-ray binaries with large mass ratios and short orbital periods are expected to change their orbital period due to magnetic breaking, mass loss...

    The quest for axions
    We introduce the strong CP problem and the existence of the Axion as a possible solution. We discuss the possibility that axions are the dark matter of the...

    The relative role of AGB stars and SNe as the first cosmic dust polluters
    Far infrared and sub-millimeter observations of quasars and normal star forming galaxies at z>6 have revealed the presence of large amounts of dust. At such...

    The SN Ia runaway LP 398-9: detection of circumstellar material and surface rotation
    A promising progenitor scenario for Type Ia supernovae (SNeIa) is the thermonuclear detonation of a white dwarf in a close binary system with another white...
