Article
Accés obertContext. 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 ... -
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
Accés obertThe 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?
