Diversity of supernovae Ia determined using equivalent widths of Si II 4000
V. Arsenijevic, S. Fabbro, A. M. Mourao +1
Spectroscopic and photometric properties of low and high-z supernovae Ia (SNe Ia) have been analyzed in order to achieve a better understanding of their diversity and to identify p…
Improved Cosmological Constraints from New, Old and Combined Supernova Datasets
M. Kowalski, D. Rubin, G. Aldering +67
We present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compi…
Light curves of five type Ia supernovae at intermediate redshift
R. Amanullah, V. Stanishev, A. Goobar +14
We present multi-band light curves and distances for five type Ia supernovae at intermediate redshifts, 0.18<z<0.27. Three telescopes on the Canary Island of La Palma, INT, NOT and…
