    OSIRIS Hα imaging of the NGC 2770 supernova factory and its satellite NGC 2770B
    In the last 12 years NGC 2770 hosted 2 standard supernovae (SNe) and one X-ray transient event (SN2008D) similar to a Gamma-Ray Burst (GRB). Given the close (27...

    Pair production of helicity-flipped neutrinos in supernovae
    The emissivity was calculated for the pair production of helicity-flipped neutrinos, in a way that can be used in supernova calculations. Also presented are...

    Part 1: A supernova search in starburst galaxies & Part 2: Starbursts and EMIR project
    With the aim of testing the relation between supernova (SN) rate and star formation rate, we conducted a SN search in a sample of local starburst galaxies (SBs)...

    Photometry of SN 2002bo with template image subtraction
    VRI photometry of the type Ia supernova 2002bo is presented. This SN exploded in a dusty region of the host galaxy NGC 3190, thus, subtraction of a template...

    Position-dependent infrared spectroscopy of M82 - 100,000 Orion nebulae?
    It is reported that 8-13-micron spectra have been obtained at several positions across the extended emission region of M82. No major differences among the...
