We show that the spectrum of the unusual transient SCP?06F6 is consistent with emission from a cool, optically thick and carbon-rich atmosphere if the transient is located at a redshift of z 0.14. The implied extragalactic nature of the transient rules out novae, shell flashes, and V838?Mon-like events as causes of the observed brightening. The distance to SCP?06F6 implies a peak magnitude of MI ?18, in the regime of supernovae (SNe). While the morphology of the light curve of SCP?06F6 around…

Modeling the Light Curve of the Transient SCP06F6
We consider simple models based on core collapse or pair-formation supernovae (SNe) to account for the light curve of the transient SCP06F6. A radioactive decay diffusion model provides estimates of
Results from a Systematic Survey of X-Ray Emission from Hydrogen-poor Superluminous SNe
We present the results from a sensitive X-ray survey of 26 nearby hydrogen-poor superluminous supernovae (SLSNe-I) with Swift, Chandra, and XMM. This data set constrains the SLSN evolution from a few
Jets in Hydrogen-poor Superluminous Supernovae: Constraints from a Comprehensive Analysis of Radio Observations
The energy source powering the extreme optical luminosity of hydrogen-stripped Superluminous Supernovae (SLSNe-I) is not known, but recent studies have highlighted the case for a central engine.
A Hubble Space Telescope survey of the host galaxies of Superluminous Supernovae
We present Hubble Space Telescope (HST) Wide Field Camera 3 UV and near-IR (nIR) imaging of 21 Superluminous Supernovae (SLSNe) host galaxies, providing a sensitive probe of star formation and
ANALYTICAL LIGHT CURVE MODELS OF SUPERLUMINOUS SUPERNOVAE: χ2-MINIMIZATION OF PARAMETER FITS
We present fits of generalized semi-analytic supernova (SN) light curve (LC) models for a variety of power inputs including 56Ni and 56Co radioactive decay, magnetar spin-down, and forward and
Late time multi wavelength observations of Swift J1644+5734: A luminous optical/IR bump and quiescent X-ray emission
We present late-time multi-wavelength observations of Swift J1644+57, suggested to be a relativistic tidal disruption flare (TDF). Our observations extend to >4 years from discovery, and show that
Broad-band emission properties of central engine-powered supernova ejecta interacting with a circumstellar medium
We investigate broad-band emission from supernova ejecta powered by a relativistic wind from a central compact object. A recent two-dimensional hydrodynamic simulation studying the dynamical
Hypercompact Stellar Systems Around Recoiling Supermassive Black Holes
A supermassive black hole ejected from the center of a galaxy by gravitational-wave recoil carries a retinue of bound stars—a hypercompact stellar system (HCSS). The numbers and properties of HCSSs

An unusually brilliant transient in the galaxy M85
TLDR
The discovery of an optical transient in the outskirts of the lenticular galaxy Messier 85 in the Virgo cluster is reported, distinctly brighter than novae, but fainter than type Ia supernovae (which is expected in a population of old stars in lenticular galaxies).

TLDR
Both the flux and color of the excess with supernova models are compared and it is shown that the data are best explained by the presence of a Type I b/c supernova at a redshift z approx.
