Nebular-Phase Spectra of Nearby Type Ia Supernovae

Melissa L. Graham, Sahana Kumar, Griffin Hosseinzadeh +8

We present late-time spectra of eight Type Ia supernovae (SNe Ia) obtained at >200 days after peak brightness using the Gemini South and Keck telescopes. All of the SNe Ia in our…

Gaia17biu/SN 2017egm in NGC 3191: The closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy

Subhash Bose, Subo Dong, A. Pastorello +55

Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I o…
