The early spectral evolution of SN 2004dt
G. Altavilla, M. Stehle, P. Ruiz-Lapuente +18
Aims. We study the optical spectroscopic properties of Type Ia Supernova (SN Ia) 2004dt, focusing our attention on the early epochs. Methods. Observation triggered soon after the S…
Type Ia SNe along redshift: the R(Si II) ratio and the expansion velocities in intermediate z supernovae
G. Altavilla, P. Ruiz-Lapuente, A. Balastegui +17
We study intermediate--z SNe Ia using the empirical physical diagrams which enable to learn about those SNe explosions. This information can be very useful to reduce systematic unc…
Supernova search at intermediate z. III. Expansion velocities of the ejecta
A. Balastegui, P. Ruiz-Lapuente, J. Mendez +6
We discuss the expansion velocities of different elements in the ejecta of the intermediate-z SNe Ia discovered as a part of the International Time Programme (ITP) project ``Omega…
Supernova search at intermediate z. II. Host galaxy morphology
J. Mendez, P. Ruiz-Lapuente, G. Altavilla +6
We discuss the host galaxy morphology of the 8 SNe discovered as a part of the International Time Programme (ITP) project ``Omega and Lambda from Supernovae, and the Physics of Sup…
Supernova search at intermediate z. I. Spectroscopic analysis
G. Altavilla, P. Ruiz-Lapuente, A. Balastegui +7
We study 8 supernovae discovered as part of the International Time Programme (ITP) project ``Omega and Lambda from Supernovae and the Physics of Supernova Explosions'' at the Europ…
