Dark Energy as an Inverse Problem
Cristina Espana-Bonet, Pilar Ruiz-Lapuente
A model--independent approach to dark energy is here developed by considering the determination of its equation of state as an inverse problem. The reconstruction of w(z) as a non-…
The Nova Stella and its Observers
P. Ruiz-Lapuente
Views on mechanics and cosmology by the observers of the supernova of 1572
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…
Optical Photometry of GRB 021004: The First Month
Stephen T. Holland, Michael Weidinger, Johan P. U. Fynbo +17
We present U,B,V,R_C,and I_C photometry of the optical afterglow of the gamma-ray burst GRB 021004 taken at the Nordic Optical Telescope between approximately eight hours and 30 da…
The cosmic rate of supernovae and the range of stars ending as Type Ia SNe
P. Ruiz-Lapuente, R. Canal
The present cosmic rate of Type Ia supernovae (SNeIa) suggests that about 6% of all stars in binary systems with primaries in the initial mass range $3-9\ M\sun$ end up as SNeIa. I…
Cosmological Insights from Supernovae
P. Ruiz-Lapuente
While low-z Type Ia supernovae are used to measure the present rate of expansion of the Universe, high-z Type Ia measure its variation due to the cosmic matter-energy content. Resu…
