Welcome to the website of the
International Time Programme (ITP)
$ \Omega$ and $ \Lambda$ from Supernovae,
and the Physics of Supernova Explosions,
This project has recently been completed at the telescopes of the European Northern Observatory (ENO) at La Palma (Canary Islands, Spain)

The two main objectives of the ITP project were:

  1. To significantly increase and intensively study the sample of intermediate-redshift (z between 0.15 abd 0.4) Type Ia supernovae (SNe Ia), which includes discovery, spectroscopic identification, and photometric follow-up.
  2. To study in detail the evolution of a number of nearby (z close to zero) SNeIa, that implying both spectroscopic and photometric follow-up.

As explained in the detailed description of the research goals, objective (1) aimed to fill the gap between the nearby SNeIa sample (as exemplified by the Calan-Tololo survey: Hamuy et al. 1996), used for SNeIa luminosity calibration, and the distant sample (z above 0.4) used to measure the cosmological parameters $ \Omega$ and $ \Lambda$. The goal of objective (2) was to provide empirical material that, when compared with the predictions of current physical models of SNeIa, could constrain them enough to discriminate among the different alternatives and thus allow a significant step forward in the way to the complete understanding of those explosions.
