Abstract:
We present light curves and classification spectra of 17 hydrogen-poor
superluminous supernovae (SLSNe) from the Pan-STARRS1 Medium Deep
Survey (PS1 MDS). Our sample contains all objects from the PS1 MDS
sample with spectroscopic classification that are similar to either of
the prototypes SN 2005ap or SN 2007bi, without an explicit limit on
luminosity. With a redshift range 0.3<z<1.6, PS1 MDS is the first SLSN
sample primarily probing the high-redshift population; our multifilter
PS1 light curves probe the rest- frame UV emission, and hence the peak
of the spectral energy distribution. We measure the temperature
evolution and construct bolometric light curves, and find peak
luminosities of (0.5-5)x1044erg/s and lower limits on the total
radiated energies of (0.3-2)x1051erg. The light curve shapes are
diverse, with both rise and decline times spanning a factor of ∼5 and
several examples of double-peaked light curves. When correcting for
the flux-limited nature of our survey, we find a median peak
luminosity at 4000Å of M4000=-21.1mag and a spread of σ=0.7mag.
Description:
The Pan-STARRS1 Medium Deep Survey (PS1 MDS) operated from late 2009
to early 2014. PS1 MDS consists of 10 fields, each with a single PS1
imager footprint. The stacked 3π survey data are publicly available
from the Space Telescope Science Institute archive.
A subset of targets was selected for spectroscopic follow-up, using
the Blue Channel spectrograph on the 6.5m MMT telescope, the Gemini
Multi-Object Spectrograph (GMOS) on the 8m Gemini telescopes, and the
Low Dispersion Survey Spectrograph (LDSS3) and Inamori-Magellan Areal
Camera and Spectrograph (IMACS) on the 6.5m Magellan telescopes.
In addition to the PS1 photometry, some objects have additional
follow-up imaging acquired with GMOS, LDSS, and IMACS. PS1-11bdn was
also observed with the Swift Ultra-Violet/Optical Telescope (UVOT).
