On the relationship between environment and galaxy properties in clusters of galaxies
Hector J. Martinez, Valeria Coenda, Hernan Muriel
We study the correlation between different properties of bright (L>L*) galaxies in clusters and the environment in the Sloan Digital Sky Survey (SDSS). Samples of clusters of galax…
Stability and mode analysis of solar coronal loops using thermodynamic irreversible energy principles II. Modes in twisted non--isothermal magnetic field configurations
A. Costa, R. Gonzalez
We study the stability and the modes of non -- isothermal coronal loop models with different intensity values of the equilibrium twisted magnetic field.We use an energy principle o…
Evolution of environment dependent galaxy properties in the Sloan Digital Sky Survey
Ana Laura O'Mill, Nelson Padilla, Diego Garcia Lambas
We use photometric redshifts to analyse the effect of local environment on galaxy colours at redshifts z < 0.63 in the SDSS data release 6. We construct mock SDSS-DR6 catalogues us…
Angular momentum-Large-scale structure alignments in LCDM models and the SDSS
Dante Paz, Federico Stasyszyn, Nelson Padilla
We study the alignments between the angular momentum of individual objects and the large-scale structure in cosmological numerical simulations and real data from the Sloan Digital…
What is the best way to measure baryonic acoustic oscillations?
Ariel G. Sanchez, Carlton M. Baugh, Raul Angulo
Oscillations in the baryon-photon fluid prior to recombination imprint different signatures on the power spectrum and correlation function of matter fluctuations. The measurement o…
The galaxy power spectrum: precision cosmology from large scale structure?
Ariel G. Sanchez, Shaun Cole
Published galaxy power spectra from the 2dFGRS and SDSS are not in good agreement. We revisit this issue by analyzing both the 2dFGRS and SDSS DR5 catalogues using essentially iden…
