Reducing the gravitational lensing scatter of Type Ia supernovae without introducing any extra bias
Jakob Jonsson, Edvard Mortsell, Jesper Sollerman
Magnification and de-magnification due to gravitational lensing will contribute to the brightness scatter of Type Ia supernovae (SNe Ia). The purpose of this paper is to investigat…
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…
Prospects for CDM sub-halo detection using high angular resolution observations
T. Riehm, E. Zackrisson, O. Moeller +2
In the CDM scenario, dark matter halos are assembled hierarchically from smaller subunits. A long-standing problem with this picture is that the number of sub-halos predicted by CD…
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…
Scrutinizing Exotic Cosmological Models Using ESSENCE Supernova Data Combined with Other Cosmological Probes
T. M. Davis, E. Mortsell, J. Sollerman +24
The first cosmological results from the ESSENCE supernova survey (Wood-Vasey et al. 2007) are extended to a wider range of cosmological models including dynamical dark energy and n…
Tentative detection of the gravitational magnification of type Ia supernovae
Jakob Jonsson, Tomas Dahlen, Ariel Goobar +2
The flux from distant type Ia supernovae (SN) is likely to be amplified or de-amplified by gravitational lensing due to matter distributions along the line-of-sight. A gravitationa…
