    The Canarias Database of Nearby Type II Supernovae
    Our aim is to present an atlas containing 35 low-resolution spectra that correspond to 19 Type II supernovae. These spectra cover different phases of...

    The Chemical Abundances of Tycho G in Supernova Remnant 1572
    We present an analysis of the chemical abundances of the star Tycho G in the direction of the remnant of supernova (SN) 1572, based on Keck high-resolution...

    The CHilean Automatic Supernova sEarch
    The CHilean Automatic Supernova sEarch (CHASE) project began in 2007 with the goal to discover young, nearby southern supernovae in order to (1) better...

    The dark energy survey 5-yr photometrically identified type Ia supernovae
    As part of the cosmology analysis using Type Ia Supernovae (SN Ia) in the Dark Energy Survey (DES), we present photometrically identified SN Ia samples using...

    The Dark Energy Survey supernova programme: modelling selection efficiency and observed core-collapse supernova contamination
    The analysis of current and future cosmological surveys of Type Ia supernovae (SNe Ia) at high redshift depends on the accurate photometric classification of...

    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 early nucleosynthesis of O and Fe
    The new observational O/Fe vs Fe/H relationship in halo dwarfs is analyzed in terms of a model of chemical evolution for the solar neighborhood. The role of...
