    • Design and Operation of the ATLAS Transient Science Server 
      Smith, K.W.; Smartt, S. J.; Young, D. R.; Tonry, J. L.; Denneau, L.; Flewelling, H.; Heinze, A. N.; Weiland, H. J.; Stalder, B.; Rest, A.; Stubbs, C. W.; Anderson, J. P.; Chen, T. -W; Clark, P.; Do, A.; Forster Burón, Francisco; Fulton, M.; Gillanders, J.; McBrien, O. R.; O'Neill, D.; Srivastav, S.; Wright, D. E. (IOP, 2020)
      The Asteroid Terrestrial impact Last Alert System (ATLAS) system consists of two 0.5 m Schmidt telescopes with cameras covering 29 square degrees at plate scale of 1.86 arcsec per pixel. Working in tandem, the telescopes ...
    • Hydrogen rich supernovae beyond the neutrino driven core collapse paradigm 
      Terreran, G.; Pumo, M. L.; Chen, T. W.; Dessart, L. (Nature Publishing Group, 2017)
      Type II supernovae are the final stage of massive stars (above 8 M-circle dot) which retain part of their hydrogen-rich envelope at the moment of explosion. They typically eject up to 15 M-circle dot of material, with peak ...
    • Investigating the properties of stripped-envelope supernovae; what are the implications for their progenitors? 
      Prentice, S. J.; Ashall, C.; James, P. A.; Short, L.; Mazzali, P. A.; Bersier, D.; Crowther, P. A.; Barbarino, C.; Chen, T.-W.; Copperwheat, C. M.; Darnley, M.

J.; Smith, K. W.; Sollerman, J.; Stalder, B.; Sullivan, M.; Taddia, F.; Valenti, S.; Vergani, S. D.; Williams, S. C.; Young, D. R. (Oxford University Press, 2019)
      We present observations and analysis of 18 stripped-envelope supernovae observed during 2013-2018. This sample consists of five H/He-rich SNe, sixH-poor/He-rich SNe, three narrow lined SNe Ic, and four broad lined SNe Ic. ...
    • LSQ13fn: A type II-Plateau supernova with a possibly low metallicity progenitor that breaks the standardised ... 
      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 ...
    • SN 2015bn: a detailed multi-wavelength view of a nearbysuperluminous supernova

      We present observations of SN 2015bn (=PS15ae = CSS141223-113342+004332 = MLS150211-113342+004333), a Type I superluminous supernova (SLSN) at redshift z = 0.1136. As well as being one of the closest SLSNe I yet discovered, ...
    • The lowest-metallicity type II supernova from the highest-mass red supergiant progenitor 
      Anderson, P.; Dessart, L.; Gutierrez, C.; Kruhler, T.; Galbany, Lluis; Jerkstrand, A.; Smartt, S.; Contreras, C.; Morrell, N.; Phillips, M.; Stritzinger, M.; Hsiao, E.; González Gaitán, Santiago; Agliozzo, C.; Castellon, Sergio; Chambers, K.; Chen, T.; Flewelling, H.; González, C.; Hosseinzadeh, G.; Huber, M.; Fraser, M.; Inserra, C.; Kankare, E.; Mattila, S.; Magnier, E.; Maguire, K.; Lowe, T.; Sollerman, J.; Sullivan, M.; Young, D.; Valenti, S. (Nature Publishing Group, 2018-07)
      Red supergiants have been confirmed as the progenitor stars of the majority of hydrogen-rich type II supernovae(1). However, while such stars are observed with masses > 25 M-circle dot (ref. (2)), detections of > 18 M-circle ...
    • The type Iax supernova, SN 2015H A white dwarf deflagration candidate
