We present the Pan-STARRS1 discovery of PS1-10afx, a unique hydrogen-deficient superluminous supernova (SLSN) at redshift z = 1.388. The light curve peaked at z P1 = 21.7 mag, making PS1-10afx comparable to the most luminous known SNe, with Mu = –22.3 mag. Our extensive optical and near-infrared observations indicate that the bolometric light curve of PS1-10afx rose on the unusually fast timescale of ~12 days to the extraordinary peak luminosity of 4.1 × 1044 erg s–1 (M bol = –22.8 mag) and… Expand

Selecting superluminous supernovae in faint galaxies from the first year of the Pan-STARRS1 medium deep survey
The Pan-STARRS1 (PS1) survey has obtained imaging in 5 bands (grizyP1) over 10 Medium Deep Survey (MDS) fields covering a total of 70 square degrees . This paper describes the search for apparentlyExpand
Spectra of Hydrogen-Poor Superluminous Supernovae from the Palomar Transient Factory
Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen. We demonstrate that these eventsExpand
Superluminous supernovae as standardizable candles and high-redshift distance probes
We investigate the use of type Ic superluminous supernovae (SLSN Ic) as standardizable candles and distance indicators. Their appeal as cosmological probes stems from their remarkable peakExpand
