Magnetized LambdaCDM inhomogeneities and the cosmic dark ages
Magnetized inhomogeneities cosmic dark ages
2011/10/13
Exact solutions of the perturbations equations in the magnetized LambdaCDM scenario are presented. They apply during the dark ages and, more specifically, after the baryons are freed from the drag of ...
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...
Average Inhomogeneities in Milky Way SNII and The PAMELA Anomaly
PAMELA Anomaly Supernova Remnant
2011/9/29
A model is presented to estimate the fraction of Supernova Type-II events (SNII) occurring inside vs. outside a spiral arm for a given star formation episode. The probability distribution function (PD...
Inhomogeneities in molecular layers of Mira atmospheres
Techniques: interferometric – Techniques: photometric – Stars: AGB and post-AGB – Stars: atmospheres – Stars: fun- damental parameters – Stars: mass-loss
2011/9/28
We obtained K-band spectro-interferometric observations of the Miras R Cnc, X Hya, W Vel, and RW Vel with a spectral resolution of 1500 using the VLTI/AMBER instrument. We obtained concurrent JHKL pho...
The influence of inhomogeneities on the large-scale expansion of the universe
influence of inhomogeneities large-scale expansion of the universe
2010/11/12
The evolution of an inhomogeneous universe composed entirely of matter is followed from an early, nearly uniform state until the time when the inhomogeneities have begun to grow large. The particular ...
