POLARIMETRY OF THE SUPERLUMINOUS SUPERNOVA LSQ14MO: NO EVIDENCE FOR SIGNIFICANT DEVIATIONS FROM SPHERICAL SYMMETRY

Leloudas, Giorgos; Patat, Ferdinando; Maund, Justyn R.; Hsiao, Eric; Malesani, Daniele; Schulze, Steve; Contreras, Carlos; D Ugarte Postigo, Antonio; Sollerman, Jesper; Stritzinger, Maximilian D.; Taddia, Francesco; Wheeler, J. Craig; Gorosabel, Javier (IOP PUBLISHING LTD, 2015)

We present the first polarimetric observations of a Type I superluminous supernova (SLSN). LSQ14mo was observed with VLT/FORS2 at five different epochs in the V band, with the observations starting before maximum light and ...

A comparative study of Type II-P and II-L supernova rise times as exemplified by the case of LSQ13cuw

Gall, H.; Polshaw, J.; Kotak, R.; Jerkstrand, A.; Leibundgut, B.; Rabinowitz, D.; Sollerman, J.; Sullivan, M.; Smartt, S.; Anderson, J.; Benetti, S.; Baltay, C.; Feindt, U.; Fraser, M.; González Gaitán, Santiago; Inserra, C.; Maguire, K.; McKinnon, R.; Valenti, S.; Young, D. (EDP Sciences, 2015)

We report on our findings based on the analysis of observations of the Type II-L supernova LSQ13cuw within the framework of currently accepted physical predictions of core-collapse supernova explosions. LSQ13cuw was ...

On the diversity of superluminous supernovae: ejected mass as the dominant factor

Nicholl, M.; Smartt, S. J.; Jerkstrand, A.; Inserra, C.; Sim, S. A.; Chen, T. W.; Benetti, S.; Fraser, M.; Gal Yam, Avishay; Kankare, E.; Maguire, K.; Smith, K.; Sullivan, M.; Valenti, S.; Young, D. R.; Baltay, C.; Bauer, F. E.; Baumont, S.; Bersier, D.; Botticella, M. T.; Childress, M.; Dennefeld, M.; Della Valle, Massimo; Elias Rosa, N.; Feindt, U.; Galbany, Lluis; Hadjiyska, E.; Le Guillou, L.; Leloudas, G.; Mazzali, P.; McKinnon, R.; Polshaw, J.; Rabinowitz, D.; Rostami, S.; Scalzo, R.; Schmidt, B. P.; Schulze, S.; Sollerman, J.; Taddia, F.; Yuan, F. (Oxford University Press, 2015)

We assemble a sample of 24 hydrogen-poor superluminous supernovae (SLSNe). Parameterizing the light-curve shape through rise and decline time-scales shows that the two are highly correlated. Magnetar-powered models can ...

LSQ13fn: A type II-Plateau supernova with a possibly low metallicity progenitor that breaks the standardised candle relation

Polshaw, J.; Kotak, R.; Dessart, L.; Fraser, M.; Gal Yam, Avishay; Inserra, C.; Sim, S. A.; Smartt, S. J.; Sollerman, J.; Baltay, C.; Rabinowitz, D.; Benetti, S.; Botticella, M. T.; Campbell, H.; Chen, T. W.; Galbany, Lluis; McKinnon, R.; Nicholl, M.; Smith, K. W.; Sullivan, M.; Takáts, K.; Valenti, S.; Young, D. R. (ESO, 2016)

We present optical imaging and spectroscopy of supernova (SN) LSQ13fn, a type II supernova with several hitherto-unseen properties. Although it initially showed strong symmetric spectral emission features attributable to ...
