    • Environment-derived constraints on the progenitors of low-luminosity Type I supernovae 
      Lyman, J. D.; James, P. A.; Perets, Hagai B.; Anderson, J. P.; Gal Yam, Avishay; Mazzali, Paolo; Percival, S. M. (Oxford University Press on behalf of the Royal Astronomical Society, 2013)
      We present a study of the properties of the host galaxies of unusual transient objects of two types, both being subluminous compared with the major classes of supernovae. Those of one type exhibit unusually strong calcium ...
    • A faint type of supernova from a white dwarf with a helium-rich companion 
      Perets, Hagai B.; Gal Yam, Avishay; Mazzali, Paolo; Arnett, D.; Kagan, D.; Filippenko, Alexei V.; Li, Weidong; Arcavi, I.; Cenko, S. Bradley; Fox, D. B.; Leonard, D. C.; Moon, D.-S.; Sand, D. J.; Soderberg, A. M.; Anderson, Joseph P.; James, P. A.; Foley, Ryan J.; Ganeshalingam, Mohan; Ofek, E. O.; Bildsten, L.; Nelemans, G.; Shen, K. J.; Weinberg, N. N.; Metzger, B. D.; Piro, A. L.; Quataert, E.; Kiewe, M.; Poznanski, Dovi (Macmillan Publishers Limited, 2010-05-20)
    • Observational constraints on the progenitor metallicities of core-collapse supernovae 
      Anderson, Joseph P.; Covarrubias, R. A.; James, P. A.; Hamuy Wackenhut, Mario; Habergham, S. M. (Royal Astronomical Society, 2010)
      We present constraints on the progenitor metallicities of core-collapse supernovae. To date, nearly all metallicity constraints have been inferred from indirect methods such as metallicity gradients in host galaxies, ...
    • On the environments of Type Ia supernovae within host galaxies 
      Anderson, J. P.; James, P. A.; Förster Burón, Francisco; González Gaitán, Santiago; Habergham, Stacey; Hamuy Wackenhut, Mario; Lyman, D. (2015)
      We present constraints on Type Ia supernovae (SNe Ia) progenitors through an analysis of the environments found at the explosion sites of 102 events within star-forming host galaxies. Hα and Galaxy Evolution Explorer ...
    • Progenitor mass constraints for core-collapse supernovae from correlations with host galaxy star formation 
      Anderson, Joseph P.; Habergham, S. M.; James, P. A.; Hamuy Wackenhut, Mario (WILEY-BLACKWELL, 2012-08)
      Using Ha emission as a tracer of ongoing (<16 Myr old) and near-ultraviolet (UV) emission as a tracer of recent (16100 Myr old) star formation, we present constraints on the properties of core-collapse (CC) supernova (SN) ...
