“…Distinguishing between progenitors of ∼10-20 M and greater than 50 M is not easily achieved with the data. SLSNe are rare, and occur only at a rate of about 1 in 10,000 -20,000 of the core-collapse population (Quimby et al 2011(Quimby et al , 2013McCrum et al 2015). It may be that a combination of very high mass (as traced by high sSFR) and low metallicity is required.…”

Host galaxy properties provide strong constraints on the stellar progenitors of superluminous supernovae. By comparing a sample of 19 low-redshift (z < 0.3) superluminous supernova hosts to galaxy populations in the local Universe, we show that sub-solar metallicities seem to be a requirement. All superluminous supernovae in hosts with high measured gas-phase metallicities are found to explode at large galactocentric radii, indicating that the metallicity at the explosion site is likely lower than the integrated host value. We found that superluminous supernovae hosts do not always have star-formation rates higher than typical star-forming galaxies of the same mass. However, we confirm that high absolute specific star-formation rates are a feature of superluminous supernova host galaxies, but interpret this as simply a consequence of the anti-correlation between gas-phase metallicity and specific star-formation rate and the requirement of on-going star formation to produce young, massive stars greater than ∼10-20 M . Based on our sample, we propose an upper limit of ∼ 0.5 Z for forming superluminous supernova progenitors (assuming an N2 metallicity diagnostic and a solar oxygen abundance of 8.69). Finally, we show that if magnetar powering is the source of the extreme luminosity then the required initial spins appear to be correlated with metallicity of the host galaxy. This correlation needs further work, but if it holds it is a powerful link between the supernova parameters and nature of the progenitor population.

“…Given the varying coverage and quality of our light curves, we do not attempt to model the full set or make inferences about the underlying distributions of parameters assuming a magnetar model. Indeed, the objects from our sample that were previously published already have magnetar fits available in the literature (Chomiuk et al 2011;Lunnan et al 2013Lunnan et al , 2016McCrum et al 2014McCrum et al , 2015Nicholl et al 2017b). Our sample contains two previously unpublished objects, PS1-11aib and PS1-12bqf, with good coverage both on the rise and decline, however, and we explore magnetar model fits to these light curves here.…”

AbstractWe 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 z 0.3 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 10 44 ( -) ergs −1 and lower limits on the total radiated energies of 0.3 2 10 51 ( -) erg. 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 4000Å of M 21.1 mag 4000 = -and a spread of 0.7 mag s = .

“…However, McCrum et al (2015) estimate that the SLSN-I rate could be up to ten times lower, based on the Pan-STARRS Medium Deep Survey over the redshift range 0.3 < z < 1.4, while Cooke et al (2012) obtain an optimistic rate of ∼ 200 yr −1…”

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-free explosions (SLSNe-I) can be seen to z ∼ 4 and therefore, offer the possibility of probing the distant Universe. Aims. We aim to investigate the possibility of detecting SLSNe-I using ESA's Euclid satellite, scheduled for launch in 2020. In particular, we study the Euclid Deep Survey (EDS) which will provide a unique combination of area, depth and cadence over the mission. Methods. We estimated the redshift distribution of Euclid SLSNe-I using the latest information on their rates and spectral energy distribution, as well as known Euclid instrument and survey parameters, including the cadence and depth of the EDS. To estimate the uncertainties, we calculated their distribution with two different set-ups, namely optimistic and pessimistic, adopting different star formation densities and rates. We also applied a standardization method to the peak magnitudes to create a simulated Hubble diagram to explore possible cosmological constraints. Results. We show that Euclid should detect approximately 140 high-quality SLSNe-I to z ∼ 3.5 over the first five years of the mission (with an additional 70 if we lower our photometric classification criteria). This sample could revolutionize the study of SLSNe-I at z > 1 and open up their use as probes of star-formation rates, galaxy populations, the interstellar and intergalactic medium. In addition, a sample of such SLSNe-I could improve constraints on a time-dependent dark energy equation-of-state, namely w(a), when combined with local SLSNe-I and the expected SN Ia sample from the Dark Energy Survey. Conclusions. We show that Euclid will observe hundreds of SLSNe-I for free. These luminous transients will be in the Euclid data-stream and we should prepare now to identify them as they offer a new probe of the high-redshift Universe for both astrophysics and cosmology.
