With peak luminosities in excess of 10^44 erg/s and total radiative outputs greater than 10^51 erg, these events push the limits of conventional supernova explosion theory. A few of these events have now been monitored by Swift, and these observations reveal high-UV luminosities as well. These super-luminous supernovae (SLSNe) are thus of great potential interest for probing the high redshift universe, but current constraints on their (time-variable) UV spectral energy distributions are weak. This leads to significant uncertainties as to the observational signatures of high-redshift SLSNe in optical or IR studies. To address this, we propose a ToO program for NUV spectroscopy to follow-up new SLSNe discoveries in Cycle 19 supplemented with Swift UV photometry and ground based optical imaging and spectroscopy from the Keck and Palomar observatories. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will acquire NUV spectra of one superluminous supernova (SLSN) with the UVIS G280 grism on WFC3 over four epochs to monitor its spectral evolution. Each observation will consist of a single orbit. The first observation should take place soon after the target is discovered and spectroscopically confirmed from the ground. Subsequent observations may be scheduled at 7 to 14 day intervals and are thus non-disruptive. 12524( 10) - 04-Jun-2012 14:02:22 - [ 2] Our targets will be supplied by PTF survey, although we could include discoveries from ROTSE-III or elsewhere in exceptional circumstances. Targets must have spectroscopically confirmed redshifts and be classified as SLSNe.
