The Berkeley Supernova Ia Program (BSNIP) has released a dataset containing over 600 spectra of 242 Type Ia supernovae (SNe Ia). The new data release, available for astronomers worldwide, was presented in a paper published ...
The most direct and strongest evidence for the accelerating universe with dark energy is provided by the distance measurements using type Ia supernovae (SN Ia) for the galaxies at high redshift. This result is based on the ...
