Studying the Ultraviolet Spectrum of the First Spectroscopically Confirmed Supernova at redshift two

M. Smith, M. Sullivan, R. C. Nichol +87

We present observations of DES16C2nm, the first spectroscopically confirmed hydrogen-free superluminous supernova (SLSN-I) at redshift z~2. DES16C2nm was discovered by the Dark Ene…

Evidence for Dynamically Driven Formation of the GW170817 Neutron Star Binary in NGC 4993

A. Palmese, W. Hartley, F. Tarsitano +89

We present a study of NGC 4993, the host galaxy of the GW170817 gravitational wave event, the GRB170817A short gamma-ray burst (sGRB) and the AT2017gfo kilonova. We use Dark Energy…

Type II supernova spectral diversity I: Observations, sample characterization and spectral line evolution

Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +23

We present 888 visual-wavelength spectra of 122 nearby type II supernovae (SNe II) obtained between 1986 and 2009, and ranging between 3 and 363 days post explosion. In this first…
