    Despite decades of intense efforts, many fundamental aspects of Type Ia supernovae (SNe Ia) remain elusive. One of the major open questions is whether the mass of an exploding white dwarf (WD) is close to the Chandrasekhar ...
  • Chandrasekhar and sub-Chandrasekhar models for the x-ray emission of type Ia Supernova remnants. I. Bulk properties 

    Martinez Rodriguez, Hector; Badenes, Carles; Lee, Shiu-Hang; Patnaude, Daniel J.; Foster, Adam; Yamaguchi, Hiroya; Auchettl, Katie; Bravo Guil, Eduardo; Slane, Patrick O.; Piro, Anthony; Park, Sangwook; Nagataki, Shigehiro (Institute of Physics (IOP), 2018-10-03)
    Article
    Open Access
    Type Ia supernovae originate from the explosion of carbon–oxygen white dwarfs in binary systems, but the exact nature of their progenitors remains elusive. The bulk properties of Type Ia supernova remnants, such as the ...
  • Evidence for a sub-Chandrasekhar-mass type Ia supernova in the Ursa Minor dwarf galaxys 

    McWilliam, Andrew; Piro, Anthony; Badenes, Carles; Bravo Guil, Eduardo (2018-04-19)
    Article
    Open Access
    A long-standing problem is identifying the elusive progenitors of Type Ia supernovae (SNe Ia), which can roughly be split into Chandraksekhar and sub-Chandrasekhar-mass events. An important difference between these two ...
  • Gamma-ray emission from SN2014J near maximum optical light 

    Isern Vilaboy, Jordi; Jean, Pierre; Bravo Guil, Eduardo; Knodlseder, Jurgen; Lebrun, François; Churazov, Eugene; Sunyaev, Rashid; Domingo, Alberto; Badenes, Carles; Hartmann, Dieter, H; Hoeflich, Peter; Renaud, Matthieu; Soldi, Simona; Elias Rosa, Nancy; Hernanz Carbó, Margarita; Domínguez Aguilera, Inmaculada; García Senz, Domingo; Lichti, G.G.; Vedrenne, G.; Von Ballmoos, Peter (EDP Sciences, 2016-04)
    Article
    Open Access
    Context. The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the thermonuclear explosion of a C/O ...
  • The origin of the iron-rich knot in Tycho's supernova remnant 

    Yamaguchi, H; Hughes, John P.; Badenes, Carles; Bravo Guil, Eduardo; Seitenzahl, Ivo R.; Martinez Rodriguez, Hector; Park, Sangwook; Petre, Robert (2017-01-09)
    Article
    Open Access
    X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta, offering unique insight into the nucleosynthesis in supernova explosions. Here we present detailed imaging and ...
