    Article
    Open Access
    We have performed deep X-ray observations of the remnant of Kepler's supernova (SN 1604) as a Key Project of the Suzaku Observatory. Our main goal is to detect secondary Fe-peak elements in the supernova (SN) ejecta to ...

    Article
    Restricted access - publisher's policy
    We explore the relationship between the models for progenitor systems of Type Ia supernovae and the properties of the supernova remnants that evolve after the explosion. Most models for Type Ia progenitors in the ...

    Article
    Open Access
    We present the results of an ongoing project to use the X-ray observations of Type Ia Supernova Remnants to constrain the physical processes involved in Type Ia Supernova explosions. We use the Tycho Supernova Remnant (SN ...
  • Is the metallicity of their host galaxies a good measure of the metallicity of Type Ia supernovae? 

    Bravo Guil, Eduardo; Badenes Montoliu, Carles (2011-06)
    Article
    Open Access
    The efficient use of Type Ia supernovae (SNIa) for cosmological studies requires knowledge of any parameter that can affect their luminosity in either systematic or statistical ways. Observational samples of SNIa commonly ...
  • Is there a hidden hole in type la supernova remnants? 

    García Senz, Domingo; Badenes Montoliu, Carles; Serichol, N. (2012-01-20)
    Article
    Open Access
    In this paper, we report on the bulk features of the hole carved by the companion star in the material ejected during a Type Ia supernova (SN Ia) explosion. In particular we are interested in the long-term evolution of the ...
  • Metallicity as a Source of Dispersion in the SNIa Bolometric Light Curve Luminosity-width Relationship 

    Bravo Guil, Eduardo; Domínguez, Inmaculada; Badenes Montoliu, Carles; Piersanti, Luciano; Straniero, Oscar (2010-02-18)
    Article
    Restricted access - publisher's policy
    The recognition that the metallicity of Type Ia supernova (SNIa) progenitors might bias their use for cosmological applications has led to an increasing interest in its role in shaping SNIa light curves. We explore the ...
  • Observation of SN2011fe with INTEGRAL - I : pre-maximum phase 

    Isern Vilaboy, Jordi; Jean, Pierre; Bravo Guil, Eduardo; Diehl, Roland; Knödlseder, Jurgen; Domingo, A.; Hirschmann, Alina; Hoeflich, Peter; Lebrun, F.; Renaud, M.; Soldi, Simona; Elias-Rosa, Nancy; Hernanz Carbó, Margarita; Kulebi, Baybar; Zhang, X.; Badenes Montoliu, Carles; Domínguez, Inmaculada; García Senz, Domingo; Jordi, Carme; Lichti, G.; Vedrenne, G.; von Ballmoos, Peter (2013-04)
    Article
    Open Access
    Context. SN2011fe was detected by the Palomar Transient Factory in M101 on August 24, 2011, a few hours after the explosion. From the early optical spectra it was immediately realized that it was a Type Ia supernova, thus ...
  • Secondary fe-peak nuclei in the tycho supernova remnant 

    Badenes Montoliu, Carles; Bravo Guil, Eduardo; Hughes, J.P. (2008)
    Conference lecture
    Open Access
    The Mn to Cr mass ratio in supernova ejecta has recently been proposed as a tracer of Type Ia SN progenitor metallicity. We review the advantages and problems of this observable quantity, and discuss them in the framework ...

    Article
    Restricted access - publisher's policy
    We propose a new method to measure the metallicity of Type Ia supernova progenitors using Mn and Cr lines in the X-ray spectra of young supernova remnants. We show that the Mn-to-Cr mass ratio in Type Ia supernova ejecta ...

    Article
    Restricted access - publisher's policy
    The evolution of Type Ia supernova binary system progenitors is highly uncertain. Several evolutionary models predict that the accretion of mass onto the white dwarf is accompanied by mass ejection from the binary in the ...
