2011/10/13
A critical analysis of three methods of estimating distances to cataclysmic variables (CVs) is performed. These methods, by Ak et al., Beuermann, and Knigge, all use near-infrared (JHK or Ks) magnitud...
Redshift and distances in a ΛCDM cosmology with non-linear inhomogeneities
cosmology: theory, relativity, large-scale structure of Universe, super- novae: general
2011/10/13
In this paper we study the effects of inhomogeneities on light propagation in a flat {\Lambda}CDM background. To this end we use exact solutions of Einstein's equations (Meures & Bruni 2011) where, st...
