  • Search for outburst events in 1.4 million galaxies

    We present an analysis of 9yr of Catalina Surveys optical photometry for 1.4 million spectroscopically confirmed SDSS galaxies. We find 717 outburst events that were not...
  • Core-collapse supernovae ages and metallicities

    Massive stars are the main objects that illuminate HII regions and they evolve quickly to end their lives in core-collapse supernovae (CCSNe). Thus, it is important to...
  • Berkeley sample of stripped-envelope SNe

    We present the complete sample of stripped-envelope supernova (SN) spectra observed by the Lick Observatory Supernova Search (LOSS) collaboration over the last three decades:...
  • Properties of 333 SNe and their 269 hosts

    We present an analysis of the impact of spiral density waves (DWs) on the radial and surface density distributions of supernovae (SNe) in host galaxies with different arm...
  • Gaia Nuclear Transient (GNT) cand.

    The high spatial resolution and precise astrometry and photometry of the Gaia mission should make it particularly apt at discovering and resolving transients occurring in, or...
  • Rate of SNe Ia in galaxy clusters

    The observed delay-time distribution (DTD) of Type-Ia supernovae (SNe Ia) is a valuable probe of SN Ia progenitors and physics, and of the role of SNe Ia in cosmic metal...
  • ASAS-SN bright supernova catalogue 2016

    This catalogue summarizes information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) and all other bright (m_peak_ <=17),...
  • Properties of 102 SNe and their 100 hosts

    We present an analysis of the height distributions of the different types of supernovae (SNe) from the plane of their host galaxies. We use a well-defined sample of 102 nearby...
  • Abundance ratio in gamma-ray burst

    The distribution of the N/O element abundance ratios calculated by the detailed modelling of different galaxy spectra at z<4 is investigated. Supernova (SN) and long...
  • ASAS-SN bright supernova catalogue 2015

    This manuscript presents information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) during 2015, its second full year of operations. The...
  • Enhanced momentum feedback from clustered SN

    Young stars typically form in star clusters, so the supernovae (SNe) they produce are clustered in space and time. This clustering of SNe may alter the momentum per SN deposited...
  • SDSS-II SN Ia BVRI photometry

    We have analysed multiband light curves of 328 intermediate-redshift (0.05<=z<0.24) Type Ia supernovae (SNe Ia) observed by the Sloan Digital Sky Survey-II Supernova...
  • ASAS-SN bright supernova catalogue 2013-2014

    We present basic statistics for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) during its first year-and-a-half of operations, spanning 2013...
  • ASASSN-15oi UBVI M2W1W2 light curves

    We present ground-based and Swift photometric and spectroscopic observations of the tidal disruption event (TDE) ASASSN-15oi, discovered at the centre of 2MASX J20390918-3045201...
  • Long-term core-collapse supernova simulations

    The next Galactic supernova is expected to bring great opportunities for the direct detection of gravitational waves (GW), full flavour neutrinos, and multiwavelength photons....
  • SN 2013ej light curves 1 to 450d after explosion

    We present optical and near-infrared photometric and spectroscopic observations of SN 2013ej, in galaxy M74, from 1 to 450 d after the explosion. SN 2013ej is a hydrogen-rich...
  • Type II supernova light curves

    High-quality collections of Type II supernova (SN) light curves are scarce because they evolve for hundreds of days, making follow-up observations time consuming and often...
  • Lists of arm and interarm supernovae

    Using a sample of 215 supernovae (SNe), we analyse their positions relative to the spiral arms of their host galaxies, distinguishing grand-design (GD) spirals from non-GD (NGD)...
  • Host galaxies of Superluminous Supernovae

    We present Hubble Space Telescope (HST) Wide Field Camera 3 UV and near-IR (nIR) imaging of 21 Superluminous Supernovae (SLSNe) host galaxies, providing a sensitive probe of...
  • Galactic SNR ^44^Ti survey

    We report the results of the deepest Galactic plane (|b|<17.5{deg}) survey in the 67.9 and 78.4keV nuclear de-excitation lines of titanium-44 (^44^Ti) performed using the...
