Abstract:
Type Ia Supernovae, thermonuclear explosions of White Dawrf stars, are
one of the building block of modern astrophysics and cosmology which
lead to the discovery of the Dark Energy which drives the Universe
apart. To decipher the nature of the Dark energy, we need a better
characterization of the spectra and the time evolution, so called light
curves.
The needed improvements boil down to increase the information by the
interplay of advanced physics models, high precision data from new
wavelength ranges by ground based and space based instruments such as
the Extremely Large Telescope, James Web Telescope (JWST), and data from
large surveys such as ZTP or the Large Synoptic Telescope (LSST) which
will provide an estimated 1,000,000 SNe or several petabyte/month but of
low quality. The future is promising but requires handling of Big Data,
advanced simulations and new AI methods to extract information between
well-defined but large and inhomogeneous data sets.
