The Mystery of Photometric Twins DES17X1boj and DES16E2bjy
M. Pursiainen, C. Gutierrez, P. Wiseman +80
We present an analysis of DES17X1boj and DES16E2bjy, two peculiar transients discovered by the Dark Energy Survey (DES). They exhibit nearly identical double-peaked light curves wh…
Superluminous Supernovae from the Dark Energy Survey
C. R. Angus, M. Smith, M. Sullivan +72
We present a sample of 21 hydrogen-free superluminous supernovae (SLSNe-I), and one hydrogen-rich SLSN (SLSN-II) detected during the five-year Dark Energy Survey (DES). These SNe,…
Probing type Ia supernova properties using bolometric light curves from the Carnegie Supernova Project and the CfA Supernova Group
Richard A. Scalzo, Emilie Parent, Christopher Burns +11
We present bolometric light curves constructed from multi-wavelength photometry of Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project and the CfA Supernova Group, usin…
SN 2012fr: Ultraviolet, Optical, and Near-Infrared Light Curves of a Type Ia Supernova Observed Within a Day of Explosion
Carlos Contreras, M. M. Phillips, Christopher R. Burns +32
We present detailed ultraviolet, optical and near-infrared light curves of the Type Ia supernova (SN) 2012fr, which exploded in the Fornax cluster member NGC 1365. These precise hi…
Rapidly evolving transients in the Dark Energy Survey
M. Pursiainen, M. Childress, M. Smith +79
We present the results of a search for rapidly evolving transients in the Dark Energy Survey Supernova Programme. These events are characterized by fast light curve evolution (rise…
Understanding Type Ia supernovae through their U-band spectra
J. Nordin, G. Aldering, P. Antilogus +39
Context. Observations of Type Ia supernovae (SNe Ia) can be used to derive accurate cosmological distances through empirical standardization techniques. Despite this success neithe…
The Superluminous Transient ASASSN-15lh as a Tidal Disruption Event from a Kerr Black Hole
G. Leloudas, M. Fraser, N. C. Stone +47
When a star passes within the tidal radius of a supermassive black hole, it will be torn apart. For a star with the mass of the Sun () and a non-spinning black hole with a…
The ANU WiFeS SuperNovA Program (AWSNAP)
Michael J. Childress, Brad E. Tucker, Fang Yuan +24
This paper presents the first major data release and survey description for the ANU WiFeS SuperNovA Program (AWSNAP). AWSNAP is an ongoing supernova spectroscopy campaign utilising…
On the nature of Hydrogen-rich Superluminous Supernovae
C. Inserra, S. J. Smartt, E. E. E. Gall +33
We present two hydrogen-rich superluminous supernovae (SLSNe), namely SN2013hx and PS15br. These objects, together with SN2008es are the only SLSNe showing a distinct, broad Halpha…
Supernova 2013by: A Type IIL Supernova with a IIP-like light curve drop
S. Valenti, D. Sand, M. Stritzinger +11
We present multi-band ultraviolet and optical light curves, as well as visual-wavelength and near-infrared spectroscopy of the Type II linear (IIL) supernova (SN) 2013by. We show t…
