PTF11rka: an interacting supernova at the crossroads of stripped-envelope and H-poor super-luminous stellar core collapses
Elena Pian, Paolo A. Mazzali, Takashi J. Moriya +17
The hydrogen-poor supernova PTF11rka (z = 0.0744), reported by the Palomar Transient Factory, was observed with various telescopes starting a few days after the estimated explosion…
The long-lived Type IIn SN 2015da: Infrared echoes and strong interaction within an extended massive shell
L. Tartaglia, A. Pastorello, J. Sollerman +41
In this paper we report the results of the first four years of spectroscopic and photometric monitoring of the Type IIn supernova SN 2015da (also known as PSN J13522411+39412…
SN 2018fif: The Explosion of a Large Red Supergiant Discovered in Its Infancy by the Zwicky Transient Facility
Maayane T. Soumagnac, Noam Ganot, Ido Irani +32
High cadence transient surveys are able to capture supernovae closer to their first light than before. Applying analytical models to such early emission, we can constrain the proge…
iPTF 16hgs: A double-peaked Ca-rich gap transient in a metal poor, star forming dwarf galaxy
Kishalay De, Mansi M. Kasliwal, Therese Cantwell +18
Calcium rich gap transients represent an intriguing new class of faint and fast evolving supernovae that exhibit strong [Ca II] emission in their nebular phase spectra. In this pap…
Light curves of hydrogen-poor Superluminous Supernovae from the Palomar Transient Factory
Annalisa De Cia, A. Gal-Yam, A. Rubin +24
We investigate the light-curve properties of a sample of 26 spectroscopically confirmed hydrogen-poor superluminous supernovae (SLSNe-I) in the Palomar Transient Factory (PTF) surv…
iPTF16asu: A Luminous, Rapidly-Evolving, and High-Velocity Supernova
L. Whitesides, R. Lunnan, M. M. Kasliwal +23
Wide-field surveys are discovering a growing number of rare transients whose physical origin is not yet well understood. Here, we present optical and UV data and analysis of iPTF16…
