Alternative Data Reduction Procedures for UVES: Wavelength Calibration and Spectrum Addition
Rodger I. Thompson, Jill Bechtold, John H. Black +1
This paper addresses alternative procedures to the ESO supplied pipeline procedures for the reduction of UVES spectra of two quasar spectra to determine the value of the fundamenta…
Dynamics of Biased Domain Walls and the Devaluation Mechanism
P. P. Avelino, C. J. A. P. Martins, L. Sousa
We study the evolution of biased domain walls in the early universe. We explicitly discuss the roles played by the surface tension and volume pressure in the evolution of the walls…
Clustering Properties of Dynamical Dark Energy Models
P. P. Avelino, L. M. G. Beca, C. J. A. P. Martins
We provide a generic but physically clear discussion of the clustering properties of dark energy models. We explicitly show that in quintessence-type models the dark energy fluctua…
Linear and non-Linear Instabilities in Unified Dark Energy Models
P. P. Avelino, L. M. G. beça, C. J. A. P. Martins
We revisit the paradigm of unified dark energy discussing in detail the averaging problem in this type of scenarios, highlighting the need for a full non-linear treatment. We also…
Scaling of cosmological domain wall networks with junctions
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We describe the results of the largest and most accurate three-dimensional field theory simulations of domain wall networks with junctions. We consider a previously introduced clas…
Reconstructing the dark energy equation of state with varying couplings
P. P. Avelino, C. J. A. P. Martins, N. J. Nunes +1
We revisit the idea of using varying couplings to probe the nature of dark energy, in particular by reconstructing its equation of state. We show that this method can be far superi…
