The history of the cosmic supernova rate derived from the evolution of the host galaxies
Kobayashi, C; Tsujimoto, T; Nomoto, K; Kobayashi, Chiaki (2000-08-10)Ne make a prediction of the cosmic supernova rate history as a composite of the supernova rates in spiral and elliptical galaxies. Ne include the metallicity effect on the evolution of Type Ia supernova (SN Ia) progenitors ... -
The origin of elliptical galaxies inferred from their metallicity gradients
Kobayashi, C (2003-04)We simulate the chemodynamical evolution of elliptical galaxies using our GRAPE-SPH code. We succeed in reproducing the observed variety of the radial metallicity gradients, from which we discuss the origin of elliptical galaxies.
