SNOC: a Monte-Carlo simulation package for high-z supernova observations
A. Goobar, E. Mortsell, R. Amanullah +3
We present a Monte-Carlo package for simulation of high-redshift supernova data, SNOC. Optical and near-infrared photons from supernovae are ray-traced over cosmological distances…
Closed cosmologies with a perfect fluid and a scalar field
Alan Coley, Martin Goliath
Closed, spatially homogeneous cosmological models with a perfect fluid and a scalar field with exponential potential are investigated, using dynamical systems methods. First, we co…
Isotropization of two-component fluids
Martin Goliath, Ulf S. Nilsson
We consider the problem of late-time isotropization in spatially homogeneous but anisotropic cosmological models when the source of the gravitational field consists of two non-inte…
Self-similar spherically symmetric cosmological models with a perfect fluid and a scalar field
Alan Coley, Martin Goliath
Self-similar, spherically symmetric cosmological models with a perfect fluid and a scalar field with an exponential potential are investigated. New variables are defined which lead…
Gravitational lensing of Type Ia supernovae
M. Goliath, E. Moertsell
Recently, Holz and Wald (1998) have presented a method for determining gravitational lensing effects in inhomogeneous universes. Their use of realistic galaxy models has been limit…
Lensing effects in an inhomogeneous universe
Lars Bergstrom, Martin Goliath, Ariel Goobar +1
Recently, Holz & Wald have presented a new method for determining gravitational lensing effects on, e.g., supernova luminosity versus redshift measurements in inhomogeneous univers…
