Near-IR Search for Lensed Supernovae Behind Galaxy Clusters - II. First Detection and Future Prospects
A. Goobar, K. Paech, V. Stanishev +11
Powerful gravitational telescopes in the form of massive galaxy clusters can be used to enhance the light collecting power over a limited field of view by about an order of magnitu…
Looking Beyond Lambda with the Union Supernova Compilation
D. Rubin, E. V. Linder, M. Kowalski +21
The recent robust and homogeneous analysis of the world's supernova distance-redshift data, together with cosmic microwave background and baryon acoustic oscillation data, provides…
Probing Dark Energy Inhomogeneities with Supernovae
Michael Blomqvist, Edvard Mortsell, Serena Nobili
We discuss the possibility to identify anisotropic and/or inhomogeneous cosmological models using type Ia supernova data. A search for correlations in current type Ia peak magnitud…
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…
The colour-lightcurve shape relation of Type Ia supernovae and the reddening law
Serena Nobili, Ariel Goobar
A study of the time sequence of optical colours of a large sample of nearby Type Ia supernovae (SNe Ia) is presented. We study the dependence of the colour time evolution with resp…
SN 2003du: 480 days in the Life of a Normal Type Ia Supernova
V. Stanishev, A. Goobar, S. Benetti +29
An extensive set of optical and NIR photometry and low-resolution spectra the Type Ia supernova (SN Ia) 2003du was obtained using a number of facilities. The observations started 1…
