    • Pan-STARRS1 Discovery of Two Ultraluminous Supernovae at z ≈ 0.9 

      Chomiuk, Laura B; Chornock, Ryan T.; Soderberg, Alicia M.; Berger, Edo; Chevalier, R. A.; Foley, R. J.; Huber, M. E.; Narayan, Gautham Siddharth; Rest, A.; Gezari, S.; Kirshner, Robert P.; Riess, A.; Rodney, S. A.; Smartt, S. J.; Stubbs, Christopher William; Tonry, J. L.; Wood-Vasey, W. M.; Burgett, W. S.; Chambers, K. C.; Czekala, Ian Philip; Flewelling, H.; Forster, K.; Kaiser, N.; Kudritzki, R.-P.; Magnier, E. A.; Martin, D. C.; Morgan, J. S.; Neill, J. D.; Price, P. A.; Roth, K. C.; Sanders, Nathan Edward; Wainscoat, R. J. (IOP Publishing, 2011)
      We present the discovery of two ultraluminous supernovae (SNe) at z ≈ 0.9 with the Pan-STARRS1 Medium Deep Survey. These SNe, PS1-10ky and PS1-10awh, are among the most luminous SNe ever discovered, comparable to the unusual ...

    • Sn 2010ay Is a Luminous and Broad-Lined Type Ic Supernova Within a Low-Metallicity Host Galaxy 

      Sanders, Nathan Edward; Soderberg, Alicia M.; Valenti, S.; Foley, R. J.; Chornock, R; Chomiuk, L; Berger, Edo; Smartt, S.; Hurley, K.; Barthelmy, S. D.; Levesque, E. M.; Narayan, G.; Botticella, M. T.; Briggs, M. S.; Connaughton, V.; Terada, Y.; Gehrels, N.; Golenetskii, S.; Mazets, E.; Cline, T.; von Kienlin, A.; Boynton, W.; Chambers, K. C.; Grav, T.; Heasley, J. N.; Hodapp, K. W.; Jedicke, R.; Kaiser, N.; Kirshner, Robert P.; Kudritzki, R.-P.; Luppino, G. A.; Lupton, R. H.; Magnier, E. A.; Monet, D. G.; Morgan, J. S.; Onaka, P. M.; Price, P. A.; Stubbs, Christopher William; Tonry, J. L.; Wainscoat, R. J.; Waterson, M. F. (IOP Publishing, 2012)
      We report on our serendipitous pre-discovery detection and detailed follow-up of the broad-lined Type Ic supernova (SN) 2010ay at z = 0.067 imaged by the Pan-STARRS1 3π survey just ∼ 4 days after explosion. The SN had a ...

    • An Ultraviolet–Optical Flare from the Tidal Disruption of a Helium-Rich Stellar Core

C.; Heckman, T.; Lawrence, A.; Norman, C.; Narayan, Gautham Siddharth; Foley, R. J.; Marion, G. H.; Scolnic, D.; Chomiuk, Laura B; Soderberg, Alicia M.; Smith, K.; Kirshner, Robert P.; Riess, A. G.; Smartt, S. J.; Stubbs, Christopher William; Tonry, J. L.; Wood-Vasey, W. M.; Burgett, W. S.; Chambers, K. C.; Grav, T.; Heasley, J. N.; Kaiser, N.; Kudritzki, R.-P.; Magnier, E. A.; Morgan, J. S.; Price, P. A. (Nature Publishing Group, 2012)
      The flare of radiation from the tidal disruption and accretion of a star can be used as a marker for supermassive black holes that otherwise lie dormant and undetected in the centres of distant galaxies1. Previous candidate ...
