The most luminous supernova to date Supernovae are exploding stars at the end of their lives, providing an input of heavy elements and energy into galaxies. Some types have near-identical peak brightness, but in recent years a new class of superluminous supernovae has been found. Dong et al.y report the discovery of ASASSN-15lh (SN 2015L), the most luminous supernova yet found by some margin. It appears to originate in a large quiescent galaxy, in contrast to most super-luminous supernovae… Expand

Extreme Supernova Models for the Super-luminous Transient ASASSN-15lh
The recent discovery of the unprecedentedly super-luminous transient ASASSN-15lh (or SN 2015L) with its UV-bright secondary peak challenges all the power-input models that have been proposed forExpand
The Unusual Super-Luminous Supernovae SN 2011kl and ASASSN-15lh
Two recently discovered very luminous supernovae (SNe) present stimulating cases to explore the extents of the available theoretical models. SN 2011kl represents the first detection of a supernovaExpand
HOST-GALAXY PROPERTIES of 32 LOW-REDSHIFT SUPERLUMINOUS SUPERNOVAE from the PALOMAR TRANSIENT FACTORY
We present ultraviolet through near-infrared photometry and spectroscopy of the host galaxies of all superluminous supernovae (SLSNe) discovered by the Palomar Transient Factory prior to 2013 andExpand
An extremely energetic supernova from a very massive star in a dense medium
The interaction of a supernova with a circumstellar medium (CSM) can dramatically increase the emitted luminosity by converting kinetic energy to thermal energy. In ‘superluminous’ supernovae of typeExpand
The supermassive black hole coincident with the luminous transient ASASSN-15lh
The progenitors of astronomical transients are linked to a specific stellar population and galactic environment, and observing their host galaxies hence constrains the physical nature of theExpand
ASASSN-15nx: A Luminous Type II Supernova with a “Perfect” Linear Decline
We present optical observations of an exceptional Type II supernova, ASASSN-15nx. Its peak luminosity at M_V = -20 mag is between those of typical core-collapse supernovae (CCSNe) and super-luminousExpand
The Most Luminous Supernovae
Recent observations have revealed an amazing diversity of extremely luminous supernovae, seemingly increasing in radiant energy without bound. We consider here the physical limits of what existingExpand
Euclid: Superluminous supernovae in the Deep Survey
Context. In the last decade, astronomers have found a new type of supernova called ‘superluminous supernovae’ (SLSNe) due to their high peak luminosity and long light-curves. These hydrogen-freeExpand
How much radioactive nickel does ASASSN-15lh require?
The discovery of the most luminous supernova ASASSN-15lh triggered a shock-wave in the supernova community. The three possible mechanisms proposed for the majority of other superluminous supernovaeExpand
ASASSN-15lh: A Superluminous Ultraviolet Rebrightening Observed by Swift and Hubble

Luminous Supernovae
TLDR
High-resolution spectroscopy of the supernova PTF 11kx is reported, which was detected on 26 January 2011 by the Palomar Transient Factory survey, and the data suggest a red giant star companion whose material got transferred to the white dwarf. Expand

Hydrogen-poor superluminous stellar explosions
TLDR
Observations of a class of luminous supernovae whose properties cannot be explained by any of the following processes: radioactive decay of freshly synthesized elements, explosion shock in the envelope of a supergiant star, and interaction between the debris and slowly moving, hydrogen-rich circumstellar material.
