The magnetar model for type I superluminous supernovae. I. Bayesian analysis of the full multicolor light-curve sample with MOSFiT
We use the new Modular Open Source Fitter for Transients to model 38 hydrogen-poor
superluminous supernovae (SLSNe). We fit their multicolor light curves with a magnetar spin …

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

SN 2020wnt: a slow-evolving carbon-rich superluminous supernova with no O ii lines and a bumpy light curve
We present the analysis of SN 2020wnt, an unusual hydrogen-poor superluminous
supernova (SLSN-I), at a redshift of 0.032. The light curves of SN 2020wnt are characterized …
