TL;DR: In this article, the authors presented high-quality light curves of 127 SNe Ia discovered by the Zwicky Transient Facility (ZTF) in 2018, which can be used to study the shape and color evolution of the rising light curves in unprecedented detail.
Journal ArticleDOI
Far-ultraviolet to Near-infrared Spectroscopy of a Nearby Hydrogen-poor Superluminous Supernova Gaia16apd
